Publicity photographs of musicians and entertainers, mostly jazz musicians, such as Duke Ellington, Louis Armstrong, Miles Davis, and Dizzy Gillespie, but including many rock and even a few classical performers. The collection also contains tape recorded radio interviews conducted between 1970 and 2003. In addition there are posters relating to musical performances.
Scope and Contents:
This collection was formed by W. Royal Stokes in the course of his professional work as a music and arts critic. It is composed primarily of publicity portraits of musical performers, both single acts and groups. The emphasis is on jazz musicians and singers, although many rock stars and groups, and other popular musical performers are included. Even a few classical musicians are represented. The pictures are primarily mass-produced black and white publicity photographs distributed to newspapers, writers, etc., by agents for entertainment personalities. Some prints were made from the original negatives, while others clearly were made from copy negatives after typography was stripped together with a print and re-photographed. However, there are some rarer original photographs included in the collection, such as personal color snapshots, higher quality prints by art photographers, etc. Nearly all the prints are unmounted, and are 8 x 10 inches or smaller in size. The bulk of the photographs date from circa 1970 to 2000, however, a number of the earlier photographs are included as well as slightly later examples.
Arrangement:
The collection is divided into nine series.

Arthur Ehrat invented and patented a breakaway basketball rim, fashioning his prototypes from bolts, metal braces and one key part: a piece of the heavy-duty coil spring on a John Deere cultivator. His invention helped to revolutionize the way basketball is played because players could slam dunk the ball with fewer injuries and without bending the rims or breaking backboards. This collection includes correspondence, legal documents --such as patent papers, litigation files and licensing agreements --photographs and sketches that relate to the basketball invention, as well as materials regarding his two field spreader patents and other invention ideas.
Scope and Contents:
The collection is divided into five series and consists of approximately seven cubic feet.
This collection includes correspondence and legal documents--such as patent papers, litigation files and licensing agreements--that relate to Arthur Ehrat's basketball goal, as well as materials regarding his field spreader patents and other invention ideas. The bulk of the collection is made up of attorney correspondence, patent infringement documents, and patent licensing documents. The collection also contains handwritten notes by Arthur Ehrat and his attorneys, sketches of his inventions, an oral history interview, and photographs.
Attorney McPherson Moore sent many of the legal documents and correspondence to Ehrat. These documents were assembled by the law firms for which Moore worked. The original order has been preserved.
The correspondence consists of letters from attorney McPherson Moore to Ehrat and from Moore or his associates to other attorneys regarding litigation, pending licensing agreements, and other actions. The correspondence contains handwritten notes, promotional materials for sporting goods companies, drafts of legal documents, copies of patents and other enclosures. The majority of the correspondence is copies.
Correspondence found throughout the collection is key to understanding the legal documents because it provides insight into the legal negotiations behind the settlement and licensing process, and the diligence necessary to protect a viable patent from infringement. Correspondence should be read in conjunction with litigation and licensing documents to gain a better sense of the negotiations between attorneys and how and why the legal documents were created.
Throughout this collection, reference is made to legal terms, including pleadings, production documents, discovery, patent infringement, file histories, and Bates numbers. Series 3, Civil Action and Settlement Records has numerous sets of pleadings, which are the legal documents filed in a lawsuit. These documents encompass complaints, petitions, answers, motions, declarations, and memoranda.
The discovery process is the effort of one party to a lawsuit to get information from the other party prior to a trial. This is done through depositions, requests for or production of documents, and interrogatories (written questions to the other party).6
Bates numbers --named after the Bates Automatic Numbering Machine patented in the late 1800s --are used to identify documents with a unique number. The parties to a lawsuit use these numbers to keep papers in order when they are sent to the other party during discovery. This collection contains sets of production documents stamped with Bates numbers. (See Series 3, Subseries 8: Ehrat v. Icon, Proform and K's Merchandise, 1984-1996)7
Patent infringement is "the manufacture and/or use of an invention or improvement for which someone else owns a patent issued by the government, without obtaining permission of the owner of the patent by contract, license or waiver."8
A patent file history (also called a file wrapper) is a folder maintained by the United States Patent and Trademark Office. It contains all of the correspondence and documents from a patent application.9 See Series 2, Subseries 2 for the file history of Ehrat's United States Patent No. 4,365,802.
Series 1: Background Materials, 1968-2005, 2011
This series, which is further divided into three subseries, comprises oral history interviews, early sketches of Ehrat's basketball goal, articles about slam dunking, Ehrat's breakaway rim, correspondence and notes, income and expense records (including legal expenses), photographs and facsimiles of photographs, and invoices from the components Ehrat purchased when he created prototypes. One receipt documents the heater Bob Copelin purchased for his new shed in 1975, around the time Ehrat began inventing. This was significant when Ehrat was trying to prove to the United States Patent Office that he had his idea before Frederick Tyner.
Subseries 1: Ehrat History, 1968-2005
Correspondence in this subseries includes a handwritten list of possible names for the basketball rim, one which Ehrat titled, "The Rebounder Has Been Tested." The correspondence also contains copies of letters sent to the United States Patent Office intended to prove that Ehrat's rim was unique; a letter from National Basketball Association saying that, after testing, it is going to use Kenneth Mahoney's (Toss Back) rim instead of Ehrat's; letters from basketball halls of fame; and copies of e-mail from the Smithsonian. This subseries has an original sketch of Ehrat's basketball goal with annotations. Also included is a 1 D2" VHS tape of Ehrat explaining the components he used to fashion his first breakaway rim prototypes and a news segment in which Ehrat was interviewed about his invention at the Chicago Board of Trade. The audio and video recordings contain some repetition of information.
Subseries 2: Photographs and Clippings, 1973-2005
Color photocopies of photographs depicting early rims; a birthday gathering for Ehrat's father, William Ehrat, circa 1974-1975 (used to help prove that he was working on the rim before Frederick Tyner); Ehrat giving a rim to Virden High School; Ehrat with sportscaster Dick Vitale; and a studio shot of his daughters, Rose, Jo, Sharon, Jane, and Linda.
Three photographs in this subseries show prototype rims with coil springs. Ehrat holds up one of these photographs in the video history, but he does not discuss the photographs' origin. There are no markings of any kind on the photographs.
Subseries 2 also contains field photographs taken by John Fleckner, National Museum of American History staff, in May 2005. Field photographs include: the grain elevator Ehrat managed; rim prototypes; and a donated rim hanging on the gym wall at Virden High School.
Articles in this subseries are from the Virden Recorder, The State Journal-Register, Chicago Tribune, The Wall Street Journal, and Kentucky Living. The topics covered include collapsible rims and breakaway rims; Ehrat and his invention; and the Smithsonian Institution's interest in the breakaway rim. Also included is a clipping from Farmers Elevator Co.'s meeting minutes from December 15, 1973, in which the board voted to relinquish rights to any patent or product created by Ehrat.
Subseries 3: Oral History Interview, 2005
A May, 2005, interview of Ehrat by John Fleckner at Ehrat's home in Virden, IL. Ehrat discusses his background, attorney Ralph Staubly, basketball rims he built, and a slam dunk contest that his nephew Randy Albrecht helped organize in the early 1980s at St. Louis Community College. Subseries 3 also contains Digital video disks (DVD) in which Ehrat discusses the documents he sent to the Archives Center, National Museum of American History. There is some repetition of topics discussed in the audio and video recordings.
Series 2: Patent Records for Basketball Rim, 1865-1984 (bulk 1970s-1984)
This series, divided into four subseries, contains copies of patents used as research or as prior art for Ehrat's patent application, a file history of the patent, correspondence/notes from Ehrat and his attorneys, and legal papers sent from Ehrat's first attorney, Ralph Staubly, to McPherson Moore.
Subseries 1: Ehrat and Dittrich Patents, 1979-1984
Copies of Ehrat's United States Patent No. 4,365,802, deformation-preventing swingable mount for basketball goals and William Dittrich's two patents, United States Patent No. 4,151,989, basketball practice device and United States Patent No. 4,465,277, basketball goal structure.
Subseries 2: Research and File History, 1865-1984
The complete patent file history consists of a list of actions taken (rejections, appeals, civil action filed) on the patent application for United States Patent No. 4,365,802. Pages 19-23 are copies of letters sent to United States Patent Office to establish the rim's unique qualities after the examiner's interference search found Frederick Tyner's patent (United States Patent No. 4,111, 420, Energy-absorbing basketball goal/backboard unit) and ruled Ehrat's invention was too similar.
Subseries 3: Correspondence and Notes, 1976-1984
Two sets of letters from acquaintances. The first set, 1977-1978, was sent to the United States Patent Office and provide a sense of the invention's unique quality. The second set, 1983-1984, consists of letters written by Ehrat's friends and was used in Basketball Products International and Ehrat v. Mt. Vernon School District and Porter (Series 3, Subseries 1) to establish that Ehrat had his breakaway rim idea before Frederick Tyner. A letter in the correspondence folder for this litigation, dated February 23, 1984, mentions that copies of these letters were sent to Basketball Products International. Also in this subseries is a transcript of a phone conversation between Ehrat and attorney McPherson Moore about when Ehrat had the idea for a breakaway rim and who knew about it.
Subseries 4: Files from Ehrat's First Attorney, Ralph Staubly, 1976-1982
Includes the file about Ehrat sent from Ralph Staubly to McPherson Moore when Ehrat changed legal representation in 1983. The folder contains originals, copies, and drafts of documents sent to the United States Patent Office, some with annotations. Also included is a high school basketball rulebook, 1977-1978, and the notes Ralph Staubly used to write an affidavit for Ehrat's patent application in which Ehrat swears he invented before Frederick Tyner.
Series 3: Civil Action and Settlement Records, 1984-1996
This series is divided into eight subseries. It contains full and partial sets of case pleadings, with pleadings indices, from eight court cases, attorney correspondence and notes, depositions of Ehrat and Frederick Tyner, case judgments, and signed settlements.
In 1984, Ehrat and Basketball Products International were plaintiffs or defendants together in five civil action lawsuits that involved sporting goods companies, including Porter Equipment Company, Gared Company, and Toss Back. These lawsuits and their correspondence should be consulted in conjunction with one another.
Subseries 1: Basketball Products International and Ehrat v. Mt. Vernon School District and Porter, 1984
Civil action, February 1984-June 1984: The complaint alleges patent infringement by sporting goods company Porter for manufacturing products embodying the invention, and infringement by Mt. Vernon School District (WA) for purchasing Porter basketball goals. Action dismissed June 11, 1984. This subseries contains the subpoena and deposition of Frederick Tyner regarding United States Patent No. 4,111, 420, Energy-absorbing basketball goal/backboard unit. It also contains plaintiff's exhibits, numbered 1-31, which include Tyner's notes, documents, and facsimiles of photographs related to his patented basketball goal.
Subseries 2: Porter Equipment Company v. Basketball Products International and Ehrat, 1984
Civil action, April 1984-June 1984: The complaint alleges that Ehrat's and Basketball Products International's patents are invalid and unenforceable and that Porter and Mt. Vernon School District did not infringe. Porter calls for dismissal or transfer of the case. The pleadings index for Vol. 1 has a note at the bottom that says "Start Vol. 2," but Vol. 2 is not in the collection.
Subseries 3: Gared Company v. Basketball Products International and Ehrat, 1984-1988
Civil action, March 1984-October 1984: This action is in response to letters sent by attorney McPherson Moore threatening a lawsuit if Gared Company does not cease manufacture of infringing goals. Gared Company files a complaint for declaratory judgment, calling the patent invalid and alleging unfair competition. A stipulated dismissal of complaint was signed by Moore and Ralph Kalish, Gared Company's legal counsel. Declaratory judgment is the judgment of a court which determines the rights of parties without ordering anything be done or awarding damages.
Of note in this subseries is the deposition of Ehrat regarding his involvement with Gared Company and the city of St. Louis, where the company is based. Gared Company's counsel, Ralph Kalish, asks Ehrat questions about his nephew, Randy Albrecht. Ehrat purchased 12 rims from Gared Company, on the advice of his nephew, for the purpose of building and testing his releasable basketball goals. Kalish tries to assess whether there was a profit motive and how Gared Company's goals factored into that.
Subseries 4: Basketball Products International and Ehrat v. Gared Company, 1984
Civil action, April 1984-June 1984: Complaint filed against Gared Company and Athletic Supply (which purchased Gared Company goals) for patent infringement. The case was dismissed.
Subseries 5: Basketball Products International and Ehrat v. Toss Back
Civil action, May 1984-June 1984: Complaint filed against Toss Back and the cities of Seattle and Tacoma (which purchased Toss Back basketball goals) for patent infringement. There is no evidence of a settlement or of court action. Toss Back signed a licensing agreement with Ehrat in 1985 (See Series 4, Licensing Agreements).
Subseries 6: Ehrat v. Gared Company and Nixdorff-Krein Industries, 1982-1990 (bulk 1987-1990)
Civil action, 1988-1990: Complaint filed against sports equipment company Gared and its parent company, Nixdorff-Krein Industries, for patent infringement. Request for passing case for settlement filed by Ehrat's attorney, McPherson Moore, and granted by the court. The signed settlement is in this subseries. This subseries has file histories of Gared Company patents. A file history (or file wrapper) is a folder kept at the United States Patent and Trademark Office that has all of the correspondence and documents from a patent application
Subseries 7: Ehrat v. Diversified Products, 1989-1994
Civil action, 1993: A complaint was filed against Diversified Products after a series of letters calling for the company to cease manufacture and sales of infringing basketball goals went unheeded. The parties were granted a consent judgment to settle out of court. The signed settlement is in this subseries.
Subseries 8: Ehrat v. Icon Health & Fitness Inc., Pro Form Fitness Products Inc., and K's Merchandise Mart, 1984-1996 (bulk 1994-1996)
The Icon Health & Fitness Inc. (hereinafter Icon) pleadings consist of two volumes, Vols. 2 and 3. Vol. 1 is missing. There is a draft of the first page of Ehrat's complaint against Icon in Box 9, Folder 3. A consent judgment was entered, and the parties settled out of court. The signed settlement is in this subseries.
There are two categories of production documents in this subseries, those for the plaintiff (three folders) and those for the defendant (seven folders), that have Bates numbers affixed to or printed on the bottom of the pages. Bates numbers are used to identify documents with a unique number. The parties to a lawsuit use these numbers to keep papers in order when they are sent to the other party during discovery.
The plaintiff's production documents include Bates numbers 1-205. Numbers 1-105 contain Ehrat's patent file history; numbers 107-205 are copies of Ehrat's licensing agreements through 1993.
In the defendant's production documents, one folder has Bates # I10001 and other numbered pages that are not in a particular order. Bates numbers I10068- I10882 include the file history for United States Patent No. 4,365,802, deformation-preventing swingable mount for basketball goals; correspondence among defendant's attorneys; copies of patents; and copies of licensing agreements through 1993.
Series 4: Licensing Agreements, 1982-2000 (bulk 1980s-1990s)
This series is divided into twenty-six subseries and encompasses materials pertaining to Ehrat's relationships with numerous companies that manufacture or sell sports equipment. These materials include correspondence and notes, licensing agreements and drafts of agreements, Dun and Bradstreet financial reports, catalogs, pamphlets, and other promotional materials. Ehrat and attorney McPherson Moore used the promotional materials to determine whether the companies were marketing or selling basketball goals that infringed on Ehrat's patent, then contacted the companies about licensing Ehrat's patent. With the exception of Subseries 1: Correspondence and Subseries 6: William Dittrich Patents, each subseries represents a different company.
To better understand Ehrat's relationships with these companies, researchers should consult Subseries 1: Correspondence, as well as the correspondence within specific subseries, in conjunction with licensing agreements and other documents in this series.
There are thirteen signed licensing agreements in this series, some of which bear original signatures. Ehrat's first licensee was with Basketball Products International, which signed an exclusive agreement in 1983. In November, 1984, after five civil action lawsuits in which Ehrat and Basketball Products International were either co-plaintiffs or co-defendants, the company signed a nonexclusive licensing agreement. Drafts of the agreements exist for some companies, but there is no evidence that the agreements were signed. In some cases, correspondence indicates which companies were not interested in entering into an agreement.
Ehrat's licensees include Huffy (signed May 1988); Basketball Products International, exclusive license (signed July 1983), nonexclusive license (signed November 1984); Toss Back (signed January 1985); Porter Equipment Company (signed 1985 and 1989); RDH Enterprises/Schutt (signed August 1991); Industrial Machine Specialties/Bison (signed January 1987); Lifetime Products (signed March 1989); Fisher-Price (owned by Quaker Oats, signed April 1988); Indian Industries/Harvard Sports (signed June 1991); McCullough (signed April 1990); and Sure Shot (signed March 1991).
Companies in this series without signed licensing agreements include Medart; Blazon-Flexible Flyer; Spang/Today's Kids; Sports and Leisure/Ideas That Sell; Wilson Sporting Goods; Hutch Sporting Goods; Aalco; Bergfeld Recreation; Future Pro; MacGregor; Pro-Bound; Architectural Design Products; and Hyland Engineering.
Settlements and licensing agreements that Ehrat signed with Gared Company, Diversified Products, and Icon appear only in Series 3, Civil Action and Settlement Records.
Subseries 6, William Dittrich Patents, contains correspondence and documents relating to the patent and royalty agreement Dittrich made with Ehrat in 1987. Dittrich had two basketball-related patents but had difficulty getting companies to license with him because there was confusion about his patents and those of Ehrat and Frederick Tyner. Dittrich contacted Ehrat's attorney, McPherson Moore, and they worked out an agreement. Ehrat acquired Dittrich's patents and they joined forces to attract licensing agreements and to split royalties and litigation settlements. Subseries 6 also has the transcript of a 1986 phone conference between William Dittrich and McPherson Moore regarding a possible joint agreement with Ehrat and the patent file history for United States Patent No. 4,151,989, basketball practice device. There is no file history for Dittrich's other patent, United States Patent No. 4,465,277, basketball goal structure, but there are pieces of the file history in this subseries. Subseries 6 also includes drafts and signed patent assignment papers and a signed licensing agreement between Ehrat and Dittrich, 1987.
Subseries 9, Lifetime Products, consists of itemized lists of attorney's fees from McPherson Moore for November 30, 1987, to February 28, 1989. The fees are for research, phone calls, photocopies, correspondence, and litigation documents for Ehrat v. Gared Company. The companies listed in these papers include Gared Company, Lifetime, Huffy, Fisher-Price, Sports and Leisure, Today's Kids, Toss Back, and Blazon.
Subseries 16, McCullough contains a Dunk-Kit (see Box 18), which Ehrat purchased in 1989. The Dunk-Kit is a set of springs and bolts that turn a set basketball goal into a breakaway goal. According to attorney McPherson Moore, the springs and bolts constituted an infringement of Ehrat's patent. McCullough disagreed with this assessment but eventually agreed to a monetary settlement.
Series 5: Field Spreader Patents and Other Ideas, 1977-2003
Subseries 1: Field Spreader Patents, 1977-2003
This subseries contains copies of Ehrat's two field spreader patents: United States Patent No. 4,358,054, field-sprayer tank-vehicle having means for on-site metering and mixing of soil-treating chemicals and United States Patent No. 4,588,127, material-spreading field vehicle having means for on-site metering and mixing of soil-treating chemicals. It also contains magazines, articles, and pamphlets on agricultural equipment and litigation documents between SoilTeq and Ag-Chem.
Subseries 2: Other Ideas, 1971-1998
In the late 1980s and early 1990s, Ehrat came up with ideas for other inventions, but none of them were patentable. This subseries has original sketches for "electric clippers with box for holding clippings;" a beverage can with multiple containers; and an "automobile refreshment temperature control." Included in the folders are letters that outline the ideas behind the inventions and the reasons they were not patented. Also included are copies of patents that relate to Ehrat's ideas.
Series 6: Toby Dittrich Files, 1889-1997
This series, which is further divided into five subseries, contains administrative records, prior art, patent records, correspondence, litigation materials, financial records, marketing and sales materials, photographs, and newspaper clippings from William A. (Toby) Dittrich. Dittrich invented the "Dunk King" break-away basketball rim in the mid 1970s while he was a physics professor at Pacific Lutheran University in Washington State. Dittrich patented and marketed his rim with mixed success before selling the rights to his patents to Arthur Ehrat in the mid 1980s. The two agreed to market and license their products independently, and cooperatively share royalties and settlements from patent infringement cases.

Biographical / Historical:
Arthur Henry Ehrat was born December 20, 1924. He grew up on a farm near Shobonier, IL, east of St. Louis. Ehrat had four sisters and a brother: Dorothea, Ruth, Bernice, Grace and Walter. Growing up on a farm during the Great Depression, Ehrat learned farming skills, including milking, baling, and operating heavy equipment such as threshing machines. After graduating from Vandalia High School he moved to Wheaton, IL, to work on a farm. From the latter part of 1945 until 1947, Ehrat was an Army medic, stationed in Fort Sheridan, IL; Camp Atterbury, IN; Fort Meade, MD; and Manila, Philippines. After his Army service, Ehrat moved back to Illinois and spent a few years farming with his brother.
In the early 1950s Ehrat lived with his sister Bernice and her family in Minneapolis while attending a two-year course at Minneapolis Business College. Upon completion of the course, he returned to Virden, IL and worked at a grain elevator. Ehrat met Mary Mardell Worth in Virden. They were married June 27, 1954, and had five daughters: Rose, Jo, Sharon, Jane and Linda. Ehrat managed the grain elevator at Farmers Elevator Co. in Lowder, IL for nearly 30 years.
In the mid-1970s, Ehrat's nephew, Randy Albrecht, a coach at St. Louis University, mentioned that basketball players were slamming the basketball ball through the rim and hurting themselves, as well as bending or breaking the rims, which were affixed directly to the backboard. The bent rims had to be straightened, causing a delay of game. While Ehrat never had a strong interest in the game of basketball, Albrecht suggested his uncle, who was known as a tinkerer, come up with a safer basketball rim. The conversation sparked a few ideas. Ehrat bought a flimsy $20 basketball rim and began building a prototype.
Basketball fans during the 1940s and 1950s didn't see many slam dunks. Despite the leaping ability of stars Bob Kurland, George Mikan, and James Clifford Pollard, aka "the Kangaroo Kid," the dunk shot was considered showboating and was often done only in practice. Basketball players, whose average size was smaller in the mid-20th century, viewed the dunk as a low-percentage shot compared with the ubiquitous jump-shot.
In 1967, the National Collegiate Athletic Association (NCAA) outlawed dunking. A few years later, Julius "Dr. J" Erving, who played professionally for the American Basketball Association's Virginia Squires, re-ignited excitement about basketball with his high-flying slams. In the first half of 1976, a few months before Ehrat first applied for a patent, the dunk was reinstated in college basketball.
At the professional level, flamboyant hoops star Darryl "Dr. Dunk" Dawkins shattered some glass backboards in the late 1970s and early 1980s, which prompted the National Basketball Association (NBA) to ban the shattering of backboards and make collapsible rims mandatory. The NBA's call for collapsible rims, along with the NCAA's reinstatement of the dunk, opened the door for innovations in basketball rims.
Collapsible rims, which folded down when pressure was applied to them, were the precursor to breakaway rims and had to be manually put back in place. Ehrat created a safer basketball rim that automatically snapped back after a slam dunk.
Ehrat's first rim, used a door spring. It was bolted to two plates, one that remained fastened while the other flexed down under pressure. The hinge was not strong enough, so he focused on creating a detent. A detent is a device that holds one mechanical part in relation to another so the device can be released when force is applied. If someone slam dunks a basketball and pulls on the rim, a detent would allow the rim to flex downward with minimal pressure on the backboard. Ehrat fitted some heavy-duty magnets between metal plates on the rim, but this did not work as he envisioned.
The turning point came when Ehrat decided to use a spring mechanism. Drawing upon his agricultural background, he pulled a spring from a John Deere cultivator, cutting it to fit the basketball rim. The thick, sturdy coil was able to withstand more than a hundred pounds of pressure before yielding downward and would push the rim back into place. In addition to the spring, he tested ball bearings, bolts, and corner braces before finding the right combination that would hold at least 150 pounds of pressure.
Once he had viable prototypes, Ehrat tested their durability. He sent one to Virden High School and enlisted Randy Albrecht, to test the other prototypes. Albrecht used his connections as a basketball coach at St. Louis Community College at Meramec to have prototypes installed at the schools where he worked. The rims were sent to other high schools and colleges by Ehrat. For more information on where the prototypes went, see his deposition in Series 3, Subseries 3. Ehrat estimated in his deposition that he built approximately 36-40 prototype rims.
It took six years, from July 1976 to December 1982, for Ehrat to receive the patent on his basketball goal (United States Patent No. 4,365,802, Deformation-preventing swingable mount for basketball goals). His application was rejected twice, with patent examiner Paul Shapiro noting that Frederick C. Tyner held a patent for a similar basketball goal (United States Patent No. 4,111, 420, energy-absorbing basketball goal/backboard unit).
Ehrat and his attorney, Ralph Staubly, pursued an appeal of the rejection. Staubly, a retired patent examiner had moved to Springfield, IL, in the 1970s to open a private practice. A major part of the appeal involved notarized letters from acquaintances who said that Ehrat's invention was unique and would be an asset to the sport of basketball. He also proved, through copies of canceled checks and a rough sketch of his invention, that he was working on his breakaway basketball goal in 1975 before Frederick Tyner conceived of his. In a 1984 deposition (Series 3, Subseries 1), Tyner placed the date of his invention near the last week of March or first week of April 1976, not long after he heard that the NCAA had reinstated dunking.
Ehrat won the appeal, effectively rendering the Tyner patent invalid. After Staubly fell ill and moved to Texas, and in early 1983, Ehrat found a new patent attorney,McPherson Moore of the St. Louis firm Rogers, Eilers and Howell, who became Ehrat's main legal counsel for approximately 20 years.
In February, 1983, two months after Ehrat received his patent, his attorney McPherson Moore sent certified letters to more than 60 sporting goods companies to announce the patent. The letters were sent to alert companies of possible infringement and to garner interest in licensing agreements.
During the basketball goal patent's 17-year lifespan, Ehrat obtained a dozen companies as licensees. Only Fisher-Price and Schutt Manufacturing signed without much difficulty. Ehrat worked to get the other companies licensed, in some cases filing patent infringement lawsuits or threatening to file them. Ehrat's first licensing agreement, signed in 1983, was with Basketball Products International.
Ehrat was involved in eight civil action lawsuits, five of which took place in 1984, when he had to prove for a second time that he had his idea for a breakaway goal before Tyner. Ehrat also defended his patent against other, similar patents issued to sporting goods companies in the early 1980s. Kenneth Mahoney of Toss Back, Charles Engle of Gared Company, and the Porter Equipment Co. all received patents for basketball goal devices, citing Ehrat's patent as prior art. Ehrat was involved in lawsuits with all three companies.
In 1986, Ehrat and attorney McPherson Moore were contacted by William "Toby" Dittrich, who held two patents --United States Patent No. 4,151,989, basketball practice device and United States Patent No. 4,465,277, basketball goal structure. Dittrich was having difficulty licensing his patents to companies because of the confusion over Ehrat's and Tyner's patents. Dittrich assigned his patents to Ehrat in 1987 and they signed a joint licensing agreement to split royalties and settlement money.
In addition to his basketball goal patent, Ehrat also holds two patents for agricultural inventions: United States Patent No. 4,358,054, field-sprayer tank-vehicle having means for on-site metering and mixing of soil-treating chemicals; and United States Patent No. 4,588,127, material-spreading field vehicle having means for on-site metering and mixing of soil-treating chemicals.
Arthur Ehrat died on July 9, 2015.

Biographical / Historical:
William Russo, renowned American jazz composer, arranger, and founder of the Chicago Jazz Ensemble, had a music career that spanned five decades and included performance, conducting and composition. During his career he worked with such diverse talents as Duke Ellington, Billy Strayhorn, Leonard Bernstein, Cannonball Adderly, Yehuidi Menuhin, Dizzy Gillespie, Seiji Ozawa, and Billie Holiday. Although critics acknowledged Russo mainly for his pioneering contributions to the big-band jazz canon, his talents extended to a far wider range of musical styles, creating groundbreaking jazz scores, rock operas, classical works, film scores, and educational textbooks on jazz orchestration and arrangement. In all, he composed over 200 pieces for jazz orchestra with more than 25 recordings of his work. In 1990, Russo received a Lifetime Achievement award from NARAS, the organization that presents the Grammy Awards.
As a young trombonist, Russo studied with Lennie Tristano, the pianist and theorist who became a leader in the progressive jazz movement. During the late 1940s, Russo led the revolutionary Experiment in Jazz band. At age 21, he became one of the chief composers/arrangers for the Stan Kenton Orchestra, one of the most innovative and influential jazz orchestras of the postwar era. In his four years with Kenton, Russo penned such classic Kenton works as "23° North – 82° West," and "Frank Speaking."
Russo made several major jazz recordings under his own name before his classical "Symphony No. 2 in C (TITANS)" received a Koussevitsky award in 1959; it was performed by the New York Philharmonic that same year under Leonard Bernstein, who had commissioned the work. This award marked Russo's "official" entry into the world of classical music. Russo continued to write major symphonic works throughout his career, including his 1992 grand opera, "Dubrovsky."
After his tenure with Kenton, in the early 1950s, Russo led his own successful bands, The Russo Orchestra in New York, and the London Jazz Orchestra, before returning to Chicago to form the Chicago Jazz Ensemble in 1065. With the Ensemble, he presented Duke Ellington's "First Concert of Sacred Music" in 1967. This was one of the rare times when Ellington allowed one of his compositions to be arranged and performed by a jazz orchestra other than his own, and was a reflection of Ellington's respect for Russo. Shortly after this performance, Russo composed a rock cantata, "The Civil War," that led him into the field of rock opera. After concentrating on classical music again in the 1970s, in the late 1980s, Russo began to re-explore the history of jazz through his revived Chicago Jazz Ensemble. In 1995, the Chicago Jazz Ensemble made history with the first-ever complete live performance of Gil Evans' and Miles Davis' "Sketches of Spain" in its original form. Recent Russo works that premiered in Chicago included "Chicago Suite No. 1," and "Chicago Suite No. 2," a recording that was published posthumously in the spring of 2003.

Scope and Contents:
The materials accumulated in this collection represent the overriding collecting passion of one individual, George H. Clark. The collection forms a documentary record of over half a century of the history of radio, with the greatest emphasis on the period 1900-1935.
The collection includes materials that span the entire history of the growth of the radio industry. It is useful for those historians and other researchers interested in technological development, economic history, and the impact of applications of technology on American life.
In particular, the collection is rich in biographical information on the men who developed the technical aspects of radio and the industry; information on the inception, growth, and activities of radio companies, most notably the National Electric Signaling Company and RCA; and in photographs of all aspects of Radioana.
While most materials document technical aspects of radio, there is much information (e.g. Series 109, 134) on broadcasting and on the early history of television.
The collection, housed in over 700 boxes (about 276 linear feet), was organized into 259 numbered "classes" or series by Clark. Sixty series numbers were never used or were eliminated by Clark and combined with other series. The unused numbers are scattered throughout the filing system. The collection also includes material from series that were eliminated. These materials were never reclassified and are included as an unprocessed series at the end of the series descriptions. The collection also contains material that was never assigned a "class" designation by Clark (Lettered Series: D, E, F, G, H).
The arrangement of the collection is Clark's own; his adaptation of the Navy filing system he helped devise in 1915. Clark periodically revised the filing system and reclassified items within it.
Clark assigned class numbers to types of equipment (e.g. broadcast receivers), systems (impulse-excited transmitters and systems), scientific theories (circuit theory), and topics (company history, biography). Box 1 contains descriptions of the classification system.
When Clark classified an item and filed it he also assigned a serial number. This classification begins with 1 (or 1A) for the first item in the class and continues with successive numbers as items were added. As a consequence, the order of individual items within a series reflects the order in which Clark filed them, not any logical relationship between the items. Clark created cross references for items dealing with more than one subject by making notations on blank sheets of paper placed in related series.
Clark made cross references between series when there was no logical relationship between them; that is, when a person using the collection would not normally look in the series. For example no cross reference would be made of an engineer from series 87 (portraits) to series 4 (biography), but one would be made from series 87 to series 142 (history of television) if the item showed the engineer, say, working on a television installation.
Clark created the insignia "SRM" as the sign on the bottom of all sheets of paper numbered by him for binding. SRM stood for Smithsonian Radio Museum. This replaced the earlier though not greatly used sign "CGM." For a time about 1930, the class number on each sheet was preceded by these: "C.G.M.", for Clark, Martin, and Goldsmith, the earliest contributors to what would become the Clark Radioana Collection. After about 1933-34 Clark used C.W.C. for Clark Wireless Collection.
There are many photographs located in most series throughout the collection. But there are also three exclusive photographic series. Lettered series A, B, C. See index; and also series descriptions under lettered series.

Biographical / Historical:
George Howard Clark, born February 15, 1881, at Alberton, Prince Edward Island, Canada, emigrated to the United States at the age of fourteen. He worked as a railroad telegraph operator for the Boston and Maine Railroad during high school and college. In his unpublished autobiography he wrote:
In 1888, when I was a lad of seven, I suddenly blossomed out as a scrapbook addict, and for years I gave up boyhood games for the pleasure of sitting in a lonely attic and 'pasting up' my books ... By 1897, in high school, I graduated to beautiful pictures, and made many large size scrapbooks ... Around that time, too, I became infatuated with things electrical, and spent many evenings copying in pen and ink the various electrical text books in the Everett, Mass., Public Library. Clark began collecting material pertaining to wireless or radio in 1902. In 1903 he graduated from the Massachusetts Institute of Technology with a Bachelor of Science degree in Electrical Engineering. During his last year of college he specialized in radio work under the instruction of Professor John Stone Stone and after graduation went to work for Stone's radio company, the Stone Telegraph and Telephone Company, of Boston.
In 1908 Clark took a competitive examination open to all wireless engineers in the United States and entered the civilian service of the Navy. He was stationed at the Washington Navy Yard, with special additional duty at the Navy's Bureau of Steam Engineering and at the National Bureau of Standards.
In 1915 Clark helped devise a classification system for Navy equipment, assigning a code number to each item. This system of classification for blueprints, photographs, reports, and general data, was prepared by Arthur Trogner, Guy Hill, and Clark, all civilian radio experts with the US Navy Department in Washington. In 1918 Clark adopted the 1915 Navy classification system for organizing the radio data he was accumulating. Clark created the term "Radioana" at this time. He began spending his evenings and weekends pasting up his collection and numbering pages. At this time he bound the accumulated material. It totaled 100 volumes.
In July 1919, after resigning from the Navy, Clark joined the engineering staff of the Marconi Telegraph Company of America, which became part of the Radio Corporation of America (RCA) later the same year. His first work was at Belmar and Lakewood, New Jersey, assisting the chief engineer, Roy A. Weagant, in his development of circuits to reduce the interference caused by static (static reduction). Clark and his wife were assigned to the unheated Engineer's Cottage. His wife decided not to stay and left for Florida. Clark moved his trunks of wireless material to the heated RCA hotel at Belmar and spent most of the winter "pasting." As Clark mentions, "From that time on I was wedded to scraps."
After a year of work in New Jersey, Clark was assigned to the sales department in New York, where he devised the "type number system" used by RCA. This type number system, for example, gave the designation UV 201 to the company's first amplifier tube.
From 1922 to 1934 Clark was in charge of RCA's newly created Show Division, which held exhibits of new and old radio apparatus at state fairs, department stores, and radio shows. About 1928 Clark started an antique radio apparatus museum for RCA. RCA's board of directors announced:
Recognizing the importance of providing a Museum for the Radio Art to house the rapidly disappearing relics of earlier days, and the desirability of collecting for it without further delay examples of apparatus in use since the inception of radio, the Board of Directors of RCA has made an initial appropriation of $100,000, as the nucleus of a fund for the establishment of a National Radio Museum. A plan for ultimately placing the museum under the wing of the Smithsonian Institution was coupled with the goal of the Institution's gathering the largest possible library of wireless data.
Around 1933 the RCA traveling exhibition program ended and Clark started classifying his collected "radioana" material. The objects of the museum were eventually turned over for exhibit purposes to the Rosenwald Museum in Chicago and the Henry Ford Museum in Dearborn, Michigan, when space was not forthcoming at the Smithsonian. A list of objects sent to the two museums (with tag and case numbers) is in Series 1, Box A. The "radioana" collection remained under Clark's care during the 1930s, and became of increasing use to RCA. Clark continued to add to the material.
Between 1934 and 1942 Clark was in court many times regarding patent infringements. Clark's wireless data was useful and he testified frequently, for example, in RCA's suit against the United States in the Court of Claims over the Marconi tuning patents and in the Westinghouse Company's suit against the United States over the heterodyne. Patent specifications and material regarding these and other radio industry suits are found throughout this collection.
In 1946 RCA retired George Clark and denied him space to house his "radioana" collection. Clark wished to remain in New York and house the collection somewhere in the city where it would be open at all times to the public and where it would be maintained. He hoped to continue cataloguing the collection and writing books from its information. He wanted to keep the collection under his control for as long as he was capable of using it.
George H. Clark died in 1956 and his collection was subsequently given to the Massachusetts Institute of Technology. In 1959 the collection was given to the Smithsonian's new Museum of History and Technology, where space was available to house it. The collection remained in the Division of Electricity until the spring of 1983 when it was transferred to the Archives Center.
Brief Company Histories From The Radio Industry, 1900-1930s:
Introduction
At the end of the nineteenth century, when Guglielmo Marconi began his first wireless company, Western Union, Postal Telegraph, and the American Telephone and Telegraph Company (AT&T) were the major enterprises in electrical communications. General Electric, Western Electric, and Westinghouse were the major producers of electrical equipment. All these earlier developments set the stage for the expansion of the radio industry.
General Electric, which dominated the lighting industry, was formed in 1892 as a merger of the Edison and Thomson-Houston companies. It was active in building central power station equipment; controlled nearly all the important early patents in electric railways; took a leading part in the introduction of trolley systems; and was the principal supplier of electric motors. Westinghouse promoted the alternating current system and installed the first AC central station in Buffalo, NY, during the winter of 1866-1867. After years of patent litigation, in 1896 GE and Westinghouse agreed to share their patents on electrical apparatus.
American Bell Telephone Company purchased Western Electric in 1881. Western Electric had a strong patent position in telephone equipment and in industrial power apparatus, such as arc lamps, generators, motors, and switchboard equipment.
Until RCA was formed in 1919, these established electrical companies played no active part in the early development of the American radio industry. They were in difficult financial positions, reorganizing, or concentrating their efforts and resources on improving their existing products.
The revolution in "wireless" technology, which began in earnest after 1900, centered in New York City, home of the Lee de Forest and American Marconi companies, and in Boston, headquarters of John Stone Stone and Reginald Fessenden.

The De Forest Companies
Lee De Forest (1873-1961), inventor of the three-element vacuum tube or triode (1906) and the feedback circuit, was one of the first Americans to write a doctoral thesis on wireless telegraphy: "The Reflection of Short Hertzian Waves from the Ends of Parallel Wires," Yale University, 1899. The grid-controlled tube or audion of De Forest was first a radio detector, 1906-1907; in 1912 was adapted to an amplifier; and later to an oscillator. When it was perfected as a high vacuum tube, it became the great electronic instrument of electrical communications.
De Forest began work in the Dynamo Department at the Western Electric Company in 1899. Six months later he was promoted to the telephone laboratory. In 1900 De Forest went to work for the American Wireless Telegraph Company where he was able to carry out work on his "responder." However, after three months when De Forest refused to turn over the responder to the company, he was fired.
In the following year De Forest had a number of jobs, was active as an inventor, and created numerous firms to manufacture his inventions. In 1901 De Forest joined with Ed Smythe, a former Western Electric colleague and a collaborator in his research, to found the firm of De Forest, Smythe, and Freeman. Between 1902 and 1906 De Forest took out thirty-four patents on all phases of wireless telegraphy. The responder that he had been working on for so long never proved satisfactory.
The numerous De Forest companies, reflected his many interests and his inability to carry one project through to a conclusion. Unlike Marconi, but similar to Fessenden, De Forest had great inventive skill which resulted in a great number of companies; but none lasted long. The original partnership of 1901 led to the Wireless Telegraph Co. of America (1901), the De Forest Wireless Telegraph Company (Maine) (1902), and the American De Forest Wireless Telegraph Company (1903), to name a few.
The American De Forest Wireless Telegraph Company was incorporated after De Forest met a stock promoter, Abraham White. While many stations were built by this company, many never sent a message due to static interference. In 1907 two speculators from Denver with large holdings of company stock put the company out of business. The assets were sold to a new company that these speculators organized, the United Wireless Telephone Company. De Forest was forced to resign. He took the triode patents with him.
De Forest joined with one of White's stock salesmen, James Dunlop Smith, and together with De Forest's patent attorney, Samuel E. Darby, they formed a new corporation, the De Forest Radio Telephone Company in 1907. This company set out to develop wireless communication by means of the radio telephone.
In January 1910 De Forest staged the first opera broadcast, with Enrico Caruso singing. The Radio Telephone Company went bankrupt in 1911 following an aborted merger with North American Wireless Corporation. In 1913 he reorganized the company as the Radio Telephone and Telegraph Company and began producing the triode.
The Marconi Company brought a patent suit, claiming the triode infringed on the Fleming valve to which it had rights. In 1916 the court decided that Marconi had infringed the three element De Forest patent and that De Forest had infringed the two element Fleming valve. The result was that neither company could manufacture the triode.
In 1920 RCA acquired the De Forest triode rights through cross-licensing agreements with AT&T which had recently purchased the rights to it. De Forest's company was no match for GE, Westinghouse, and RCA. The De Forest Radio Company (1923) went bankrupt in 1928, was reorganized in 1930, and went into receivership in 1933. RCA eventually purchased its assets.
Marconi Companies
Guglielmo Marconi (1874-1937) came from a wealthy and well connected Italian family. He was able to spend his time developing his inventions and following his own course of action. Marconi spent his entire life developing wireless communication into a "practical" reality. In 1905 Marconi invented a directional antenna. In 1909 he shared with Karl Ferdinand Braun the Nobel prize in physics. And in 1912 he invented the time spark system for the generation of continuous waves. The principal patents in his name were improved types of vertical antennas; improved coherer; magnetic detector for the detection of wireless signals; and improvements on methods of selective tuning. Two other inventions of great importance to the Marconi companies' patent structure were the Oliver Lodge tuning patent and the Ambrose Fleming valve.
In 1895 Marconi made the first successful transmission of long wave signals. The following year he met William Preece, engineer-in-chief of the British Post Office, who was interested in inductive wireless telegraphy. This meeting led to the formation in 1897 of the Marconi Wireless Telegraph Company Ltd. In 1898 he transmitted signals across the English Channel. In 1899 an American subsidiary was formed. The various Marconi companies were the dominant enterprises in both British and American wireless until 1919 when RCA was formed.
From a business standpoint, wireless did not become profitable until long distance communications were accomplished. On December 12, 1901 in St. John's, Newfoundland, Marconi received a telegraph signal in the form of repetitions of the Morse telegraphic letter "S" transmitted from the Marconi station at Poldhu, Cornwall, England. This success, however, was met by opposition from vested interests, particularly the Anglo-American Telegraph Company whose cables terminated in Newfoundland.
So as not to restrict his company's future to one front alone, Marconi decided to exploit the field of communication with ships at sea. In order to control this field he decided in 1900 to lease his apparatus rather than sell it outright. This strategy did not work. Competition developed in Germany (Telefunken Corporation) and the United States (American De Forest and its successor, United Wireless) and Marconi was forced to sell rather than lease apparatus to the navies of various countries. He nevertheless retained numerous restrictions. This led to further friction. At the height of this debacle English stations worldwide refused to communicate with ships without Marconi equipment. This absurd and dangerous situation had to change and coastal stations opened up to all senders in 1908.
Marconi's system was based on spark technology. He saw no need for voice transmission. He felt the Morse code adequate for communication between ships and across oceans. He, along with most others, did not foresee the development of the radio and the broadcasting industry. He was a pragmatist and uninterested in scientific inquiry in a field where commercial viability was unknown.
For these reasons Marconi left the early experimentation with the radio telephone to others, particularly Lee De Forest and Reginald Fessenden.
National Electric Signaling Company
Canadian-born Reginald Fessenden (1866-1932), one of the principal early radio inventors and the first important inventor to experiment with wireless, left the University of Pittsburgh in 1900 to work for the U.S. Weather Bureau. There he invented the liquid barretter, an early radio receiver, and attempted to work out a means for wireless transmission of weather forecasts. After a squabble over patent rights, Fessenden resigned in 1902.
The National Electric Signaling Company (NESCO), primarily intended to support Fessenden's work on wireless, telegraphy, and telephony, was formed by Fessenden and two Pittsburgh capitalists, Hay Walker, Jr. and Thomas H. Given. It began as an inventor's laboratory and never proved successful as a business venture.
Fessenden recognized that a continuous wave transmission was required for speech and he continued the work of Nikola Tesla, John Stone Stone, and Elihu Thomson on this subject. Fessenden felt he could also transmit and receive Morse code better by the continuous wave method than with a spark-apparatus as Marconi was using.
In 1903 Fessenden's first high-frequency alternator needed for continuous wave transmission was built to his specifications by Charles Steinmetz of GE. In 1906 Fessenden obtained a second alternator of greater power from GE and on Christmas Eve broadcast a program of speech and music. The work on this alternator was given to Ernst F. W. Alexanderson. It took years for Alexanderson to develop an alternator capable of transmitting regular voice transmissions over the Atlantic. But by 1916 the Fessenden-Alexanderson alternator was more reliable for transatlantic communication than the spark apparatus.
Fessenden also worked on continuous-wave reception. This work arose out of his desire for a more effective type of receiver than the coherer, a delicate device that was limited by its sensitivity on a rolling ship at sea. In 1903 he developed a new receiving mechanism - the electrolytic detector.
As his work progressed Fessenden evolved the heterodyne system. However, due to faulty construction and the fact that it was ahead of its time, heterodyne reception was not fully appreciated until the oscillating triode was devised, thus allowing a practical means of generating the local frequency.
Between 1905 and 1913 Fessenden developed a completely self-sustaining wireless system. However, constant quarrels between Fessenden, Walker, and Given culminated in Fessenden's forming the Fessenden Wireless Company of Canada. He felt a Canadian company could better compete with British Marconi. As a result, his backers dismissed Fessenden from NESCO in January of 1911. Fessenden brought suit, won, and was awarded damages. To conserve assets pending appeal, NESCO went into receivership in 1912, and Samuel Kintner was appointed general manager of the company.
In 1917 Given and Walker formed International Signal Company (ISC) and transferred NESCO's patent assets to the new company. Westinghouse obtained majority control of ISC through the purchase of $2,500,000 worth of stock. The company was then reincorporated as The International Radio Telegraph Company. The Westinghouse-RCA agreements were signed in 1921 and International's assets were transferred to RCA.
RCA
The development of the radio industry accelerated after 1912. This was due to several factors, the most important of which was the passage of legislation by the US government requiring ships at sea to carry wireless. This created a market incentive and spurred the growth of the industry. Also, with the outbreak of World War I, the larger electrical companies turned their manufacturing output to radio apparatus, supporting the war effort. Three firms were prominent in this industrial endeavor: AT&T, GE, and Westinghouse.
AT&T's early contributions to this effort centered on their improvements of De Forest's triode, particularly in the evolution of circuits, the redesign of the mechanical structure, and an increase in the plate design. The importation of the Gaede molecular pump from Germany created a very high vacuum. The resulting high-vacuum tube brought the practical aspects of the wireless telephone closer to reality. By August 1915 speech had been sent by land wire to Arlington, Va., automatically picked up there via a newly developed vacuum-tube transmitter, and subsequently received at Darien, Canal Zone. By 1920 AT&T had purchased the rights to the De Forest triode and feedback circuit, and had placed itself in a strong position in the evolution of radio technology.
GE centered its efforts on the alternator, assigning Ernst F. W. Alexanderson to its design, and on further development of vacuum tube equipment for continuous wave telegraph transmission. By 1915 Alexanderson, Irving Langmuir, William D. Coolidge, and others had developed a complete system of continuous wave transmission and reception for GE.
As can be seen, both AT&T and GE were diverting major time and expenditures on vacuum tube research. This inevitably led to patent interferences and consequently, to cross-licensing arrangements.
Westinghouse was not in the strategic position of GE and AT&T. Nevertheless, during the war it did manufacture large quantities of radio apparatus, motors, generators, and rectifiers for the European and American governments. Postwar moves led Westinghouse into full partnership with the other two companies.
By the end of the war, all three companies had committed significant resources to wireless. They were hampered internationally, however, by the Marconi Company's dominant status, and in the United States they were blocked by opposing interests with control of key patents.
The US government also was concerned with this lack of solidarity in the wireless industry and over the British domination of the field worldwide. This impasse set a fascinating and complicated stage for the formation of the RCA.
Owen D. Young, legal counselor for GE, was instrumental in breaking the impasse. Through an innovative and far-reaching organizational consolidation, Young was able to persuade British Marconi that persistence in monopoly was a fruitless exercise, because of the strong US government feelings. Marconi, realizing the harm of a potential American boycott, finally agreed to terms. GE purchased the controlling interest in American Marconi, and RCA was formed. Young was made chairman of the board of RCA, while Edwin J. Nally and David Sarnoff of the old American Marconi were appointed president and commercial manager respectively.
On July 1, 1920, RCA signed a cross-licensing agreement with AT&T. The telephone company purchased one half million shares of RCA common and preferred stock for several considerations -- the most important being that all current and future radio patents of the two companies were available to each other royalty-free for ten years. Many provisions of these agreements were ambiguous and led to later squabbles between the RCA partners.
In May 1920 Westinghouse, which had an efficient radio manufacturing organization, formed an alliance with the International Radio and Telegraph Company (NESCO's successor). Westinghouse's part ownership gave them control of Fessenden's patents, particularly continuous-wave transmission and heterodyne transmission. Westinghouse also wisely purchased in October of 1920 Armstrong's patents on the regenerative and superheterodyne circuits -- which also included some of Columbia University professor Michael Pupin's patents. This placed Westinghouse in a strong bargaining position vis-à-vis RCA and in their new consolidated corporation. Westinghouse joined the growing group of radio companies on June 30, 1921. With these mergers, RCA agreed to purchase forty percent of its radio apparatus from Westinghouse and sixty percent from GE.
Through these and other legal arrangements, RCA obtained the rights to over 2,000 patents. These amounted to practically all the patents of importance in the radio science of that day. As a result, other firms in the radio industry, for example, the United Fruit Company and the Wireless Specialty Apparatus Company, entered into cross-licensing arrangements with RCA.
RCA also made arrangements internationally with the three dominant companies in radio communication in their respective countries. British Marconi, Compagnie Generale de Telegraphie sans fil, and Telefunken. Each corporation was given exclusive rights to use the other companies' patents within their own territories.
The rise of amateur radio in the 1920s and, to a greater extent, the demand for new products by the general public contributed to the rise of the broadcasting industry. This put a strain on the earlier agreements between the major radio corporations and between 1921 and 1928 there was a struggle over patents for control of the evolving medium.
An initial attempt by AT&T to control the broadcasting industry -- using its earlier cross-licensing agreements to manufacture radio telephone transmitting equipment -- began with AT&T's disposal of RCA stock holdings in 1922-1923. It ended in 1926 with a new cross-licensing agreement which gave AT&T exclusive patent rights in the field of public service telephony and gave GE, RCA, and Westinghouse exclusive patent rights in the areas covered by wireless telegraphy, entertainment broadcasting, and the manufacture of radio sets and receiving tubes for public sale.
In 1926 after the agreements were finalized, RCA, GE, and Westinghouse joined forces and established the National Broadcasting Company (NBC). Fifty percent of the stock went to RCA, thirty percent to GE, and twenty percent to Westinghouse. The new company was divided into three divisions: the Red, Blue, and Pacific Networks. Independent, competing networks soon emerged. William S. Paley and his family formed the Columbia Broadcasting System (CBS) in 1927. The Mutual Broadcasting System was formed in 1934.
By 1928 RCA had strong patent positions in all major areas of the radio industry, including the research, development and manufacture of vacuum tubes and speakers. Most small companies entering the industry in the 1920s produced their products based on prior research by others and on expired patents. An RCA license, therefore, was essential for the manufacture of any modern radio set or vacuum tube.
In the late 1920s new developments in the reproduction of sound, produced significant changes in the phonograph industry. Among those new developments were the introduction of the electronic record, and the marketing of the Radiola 104 Loudspeaker in 1926. In 1929 RCA purchased the Victor Talking Machine Company. This changed not only the quality but the sales of the phonograph and the phonograph record. A new entertainment industry was born and an ever-expanding market for consumer products was created with cultural implications that continue today.
Telefunken
German industrialists were eager to break the Marconi Company's monopoly. Although Marconi had patents on his inventions in Germany, the Germans developed a rival system through the Telefunken Corporation, incorporated in 1903, based on the inventions of Professor Ferdinand Braun, Dr. Rudolf Slaby, and Count George von Arco.
Before 1903 the Braun-Siemens and Halske system had been developed by Gesellschaft fur Drahtlose Telegraphie (GFDT). The Slaby-Arco system had been developed by Allgemeine Electrizitats-Gesellschaft. After litigation over patents, the German court handed down a decision in favor of the GFDT. The Kaiser, with national interests in mind, ordered that the rivalry cease. The two systems were amalgamated under GFDT, and became known as the Telefunken.

Mellon Garden (Pittsburgh, Pennsylvania)
Scope and Contents:
31 digital images (2007-2019), 14 35 mm slides (circa 1980) and 2 file folders including copies of historic photographs (dates unknown, 1956, 1970, 1974) and a copy of the 1934 Country Life pictorial feature on the Mellon garden.
Varying Form:
Also known as Mellon Estate.
General:
Persons associated with the garden include: Richard Beatty Mellon and Jennie King Mellon (former owners, 1910-1938); Richard King Mellon (former owner, 1938-1943); City of Pittsburgh (owner, 1943- ); Ferruccio Vitale (1875-1933) & Alfred Geiffert, Jr. (1890-1957) and Gilmore D. Clarke (landscape architects, 1927-1929); Frederick R. Bonci and Natalie Byrd Plecity, LaQuatra Bonci Associates (landscape architects, 2005- ); Edmond Romulus Amateis (1897-1981) (sculptor of fountain, 1929); Samuel Yellin (1885-1940) (iron work, 1929); Janet C. Zweig (1950- ) (artist, 2008-2010); Hal Hilbish (lighting designer, circa 2008).
The half-acre walled garden was the renaissance garden situated behind the grand estate of the Mellon family; the mansion was demolished in 1940. Land was donated to Pittsburgh and maintained as a public park, but gardens inevitably declined. The nonprofit Pittsburgh Parks Conservancy, members of the Garden Club of Allegheny County and master gardeners provided maintenance, but the restoration of this garden was impelled by the desire of the Seamans family to create a memorial for their daughter, Ann Katherine Seamans. Original features remained: the tapestry brick wall on three sides, limestone steps for the classical processional through the garden, two Samuel Yellin wrought iron gates, and the pink granite fountain by sculptor Edmond R. Amateis backed by a terrace and stone wall. A raised octagonal flower bed below the steps was reconstructed, and holly hedges partially form a fourth wall where the house stood. Restored flagstone walkways around the rectangular lawn are bordered by plantings on either side including allées of Japanese stewartia, sun and shade perennials, spring bulbs, black gum trees for shade, understory magnolia and serviceberry, and woody shrubs including oakleaf hydrangea and Delaware Valley azaleas. The walled garden was reopened as a public park in 2010.
The memorial is an art installation within the lawn: 150 fiber optic light sticks depicting constellations, planets and stars as they were over Pittsburgh on the day and time of Ann Seamans' birth. Each light is labeled on a small disk and there is an interpretive sign on a raised overlook with a limestone bench in one corner. Artist Janet Zweig conceived the project that was installed by wiring each light stick into conduits under the lawn. The garden has park benches around the perimeter and lightweight movable furniture on the terrace.
