Summary:
The Rockwell Kent papers measure 88.0 linear feet and date from circa 1840 to 1993 with the bulk of the collection dating from 1935 to 1961. The collection provides comprehensive coverage of Kent's career as a painter, illustrator, designer, writer, lecturer, traveler, political activist, and dairy farmer.
Scope and Content Note:
The Rockwell Kent papers measure 88 linear feet and date from circa 1840 to 1993 with the bulk of the collection dating from 1935 to 1961. The collection provides comprehensive coverage of Kent's career as a painter, illustrator, designer, writer, lecturer, traveler, political activist, and dairy farmer.

Circumstances surrounding the acquisition of the papers are highlighted in an article by Garnett McCoy ("The Rockwell Kent Papers," in the Archives of American Art Journal, 12, no. 1 [January 1972]: 1-9), recommended reading for researchers interested in the collection. The collection is remarkably complete, for in the mid 1920s Kent began keeping carbon copies of all outgoing letters, eventually employing a secretary (who became his third wife and continued her office duties for the remainder of Kent's life).

Series 1: Alphabetical Files contain Kent's personal and professional correspondence, along with business records of the dairy farm and associated enterprises; also included are printed matter on a wide variety of topics and promotional literature relating to organizations and causes of interest to him. Voluminous correspondence with his three wives, five children, and other relatives, as well as with literally hundreds of friends, both lifelong and of brief duration, illuminates Kent's private life and contributes to understanding of his complex character. Among the many correspondents of note are: his art teachers William Merritt Chase, Robert Henri, and Kenneth Hayes Miller; fellow artists Tom Cleland, Arthur B. Davies, James Fitzgerald, Hugo Gellert, Harry Gottleib, Marsden Hartley, Charles Keller, and Ruth Reeves; collectors Duncan Phillips and Dan Burne Jones; critics J. E. Chamberlain and Walter Pach; and dealers Charles Daniel, Felix Wildenstein, and Macbeth Galleries. Kent corresponded with such diverse people as Arctic explorers Peter Freuchen, Knud Rasmussen, and Vilhjalmar Steffanson; composer Carl Ruggles and songwriters Lee Hays and Pete Seeger; civil rights pioneers Paul Robeson and Dr. W. E. B. Du Bois; writers Bayard Boyesen, Scott and Helen Nearing, and Louis Untermeyer; and art historian and print curator Carl Zigrosser.

Kent's interest and involvement in the labor movement are reflected in correspondence with officials and members of a wide variety and large number of unions and related organizations, among them: the Farmers' Educational and Cooperative Union of America, Farmers' Union of the New York Milk Shed, International Workers Order, National Maritime Union, and United Office and Professional Workers of America. Of special interest is his participation, often in leadership roles, in various attempts to organize artists. Files on the American Artists' Congress, Artists League of America, The Artists Union, United American Artists, and United Scenic Artists contain particularly valuable material on the movement.

A supporter of New Deal efforts to aid artists, Kent was actively interested in the various programs and often was critical of their limitations; he advocated continuing federal aid to artists after the Depression abated. The Kent papers include correspondence with the Federal Arts Project, Federal Fine Arts Project, Federal Writers Project, and the War Department, as well as correspondence with the Citizens' Committee for Government Art Projects and President Franklin D. Roosevelt on the subject.

Kent's professional correspondence documents exhibitions, sales, consignments, and reproduction of prints and paintings. He kept meticulous records of his advertising commissions and illustration work. Detailed correspondence with publishers and printers indicates Kent's involvement in the technical aspects of production and provides a good overview of the publishing industry during the mid-twentieth century.

Business records of Asgaard Farm include records of the dairy and transfer of ownership to its employees, tax and employee information, and documents concerning several related business ventures such as distributor ships for grain, feed, and farm implements.

Series 2: Writings consists of notes, drafts, and completed manuscripts by Rockwell Kent, mainly articles, statements, speeches, poems, introductions, and reviews. The Kent Collection given to Friendship House, Moscow, in 1960, was augmented later by a set of his publications and the illustrated manuscripts of many of his monographs. Also included are a small number of manuscripts by other authors.

Series 3: Artwork consists mainly of drawings and sketches by Kent; also included are works on paper by other artists, many of whom are unidentified, and by children.

Series 4: Printed Matter consists of clippings, exhibition catalogs and announcements, brochures, broadsides, programs, and newsletters. These include items by and about Kent and his family, as well as articles written and/or illustrated by him, and reviews of his books. There is also material on a variety of subjects and causes of interest to him. Additional printed matter is included among the alphabetical files, mainly as attachments to correspondence.

Series 5: Miscellaneous includes biographical material, legal documents, and memorabilia. Artifacts received with papers include textile samples, a silk scarf, dinnerware, ice bucket, and rubber stamp, all featuring designs by Rockwell Kent. Also with this series are a variety of documents including a phrenological analysis of an ancestor, lists of supplies for expeditions, a hand-drawn map of an unidentified place, and technical notes regarding art materials and techniques.

Series 6: Photographs includes photographs of Kent, his family and friends, travel, and art number that over one thousand. Also included here are several albums of family and travel photographs.
Arrangement:
The collection is arranged into six series. Series 1 is arranged alphabetically. The arrangement of the remaining series is explained in each series description. Note that sealed materials that became available in 2000 were microfilmed separately on reels 5740-5741, but have integrated into this finding aid.

Biographical Note:
Rockwell Kent (1882-1971), an energetic and multitalented man, pursued many interests and careers during his very long and active life. At various times he was an architect, draftsman, carpenter, unskilled laborer, painter, illustrator, printmaker, commercial artist, designer, traveler/explorer, writer, professional lecturer, dairy farmer, and political activist.

While studying architecture at Columbia University, Kent enrolled in William Merritt Chase's summer school at Shinnecock Hills, Long Island. He then redirected his career ambitions toward painting and continued to study with Chase in New York. Kent spent a summer working and living with Abbott H. Thayer in Dublin, New Hampshire, and attended the New York School of Art, where Robert Henri and Kenneth Hayes Miller were his teachers.

Critically and financially, Kent was a successful artist. He was very well known for his illustration work--particularly limited editions of the classics, bookplates, and Christmas cards. He was a prolific printmaker, and his prints and paintings were acquired by many major museums and private collectors. During the post-World War II era, Kent's political sympathies resulted in the loss of commissions, and his adherence to artistic conservatism and outspoken opposition to modern art led to disfavor within art circles. After many years of declining reputation in this country and unsuccessful attempts to find a home for the Kent Collection, Kent gave his unsold paintings--the majority of his oeuvre--to the Soviet Union, where he continued to be immensely popular.

An avid traveler, Kent was especially fascinated by remote, Arctic lands and often stayed for extended periods of time to paint, write, and become acquainted with the local inhabitants. Between 1918 and 1935, he wrote and illustrated several popular books about his experiences in Alaska, Tierra del Fuego, and Greenland. In the 1930s and 1940s, Kent was much in demand as a lecturer, making several nationwide tours under the management of a professional lecture bureau; he spoke mainly about his travels, but among his standard lectures were some on "art for the people."

In 1927, Kent purchased Asgaard Farm at AuSable Forks, New York, in the Adirondacks, where he lived for the remainder of his life, operating a modern dairy farm on a modest scale for many years.

As a young man, Kent met Rufus Weeks, became committed to social justice, and joined the Socialist Party. Throughout his life, he supported left-wing causes and was a member or officer of many organizations promoting world peace and harmonious relations with the Soviet Union, civil rights, civil liberties, antifascism, and organized labor. Kent was frequently featured as a celebrity sponsor or speaker at fund-raising events for these causes. In 1948, he ran unsuccessfully as the American Labor Party's candidate for Congress. Kent's unpopular political views eventually led to the dissolution of his dairy business, resulted in a summons to appear before the House Un-American Activities Committee, and prompted the U.S. State Department to deny him a passport, an action that subsequently was overturned by the U.S. Supreme Court.

Kent wrote two autobiographies, This Is My Own (1940) and It's Me, O Lord (1955). In 1969, he was the subject of an oral history interview conducted by Paul Cummings for the Archives of American Art.

Biographical / Historical:
Grace Murray Hopper (1906-1992) obtained her Ph.D. in mathematics from Yale University in 1934. She was an associate professor of mathematics at Vassar College when she joined the Women's Reserve of the United States Navy, Women Accepted for Volunteer Emergency Service (WAVES) in 1944 and was assigned to the computing project at Harvard University. She served under Commander Howard H. Aiken as a Wave until 1946, and remained at Harvard's Computation Laboratory as a research fellow until 1949. In that year she joined the Eckert-Mauchly Computer Corporation as a senior mathematician. When Eckert-Mauchly became a division of Remington Rand, Hopper remained as senior programmer, a title she retained until 1959. Subsequently, she served as systems engineer and director of automatic programming development (1959-1964) and staff scientist in systems programming (1964-1971) for the UNIVAC division of Sperry Rand Corporation. Hopper retired from UNIVAC in 1972, having returned to active service in the U.S. Navy from which she eventually retired with the rank of Rear Admiral.

The collection includes correspondence and internal company reports and memoranda; design drawings; research notes; engineering notebooks, technical notes, schematics; photographs, slides and negatives; video and audiocassettes; advertisements; product literature, magazine articles and newspaper clippings; press releases; and user guides and manuals. In Series 1, Operational Materials, Subseries 3, Weekly Reports, 1988-1996, provides an excellent overview of the issues facing the company and what actions/decisions were made and in Series 3, Engineering and Product Development Materials, Subseries 8, Technical Product Development Seminars provide a good foundation for understanding what the product development staff accomplished.

The core team of players who developed, tested and brought to market the GPS devices included: Janice Jones Blankenhorn, Gary Barta, John Foukos, Randy Hoffman, Norm Hunt, Sab Ifune, Don Rea, Dennis Rich, Ed Tuck, Jon Vavrus, Larry Weill, Val Fife Wong, and James Yuan. The majority of the core team were software and hardware engineers as well as mechanical designers. Their energy, enthusiasm, vision, and unwillingness to fail produced the first handheld commercial GPS receiver in 1989 and Magellgan was the first company to make GPS devices affordable to consumers.

Series 1, Operational Materials, 1988-1993, is divided into four subseries: Subseries 1, Organizational Materials, 1988-1994; Subseries 2, Strategic and Operating Plans, 1989-1995; Subseries 3, Weekly Reports, 1988-1996; and Subseries 4, Company Newsletters, 1991-1992.

Subseries 1, Organizational Materials, 1988-1994, consists of an organizational chart detailing Magellan's corporate structure, a document discussing the communication and functional objectives of the company, and a company Christmas card.

Subseries 4, Breadboard Design, 1986-1994, consists of memoranda, technical notes, drawings, and sketches detailing the radio frequency breadboard design. Magellan's first-generation breadboard, circa 1987, was developed by the team of Janice Jones Blankenhorn, Val Fife Wong, Ed Tuck, Norm Hunt, Sab Ifune, Gary Barta, Larry Weill, Randy Hoffman, and Don Rea.

Subseries 5, First Generation (NAV 1000/NAV 1200), 1985-1994, consists of technical notes, design notes, memoranda, drawings, and blueprints documenting the development of the first generation (primarily the NAV 1000/NAV 1200), handheld GPS unit produced by Magellan. The first generation of GPS were single channel receivers and were quite simple. The NAV 1000 was 8.75" x 3.5" x 2.25" and weighed only 1.5 pounds. The NAV 1000 converted GPS satellite information into a satellite/navigation (sat/nav) positioning. It used Gallium arsenide (GaAs) a compound of the elements gallium and arsenic, and monolithic microwave integrated circuit (MMIC) technology to reduce its size and power consumption. GaAs is a semiconductor used in the manufacture of devices such as microwave frequency integrated circuits, monolithic microwave integrated circuits, infrared light-emitting diodes, laser diodes, solar cells, and optical windows. The device sold for approximately $3,000 dollars.

Subseries 6, Second Generation, 1988-1996, consists of technical notes, design notes, memorandums, drawings, and blueprints documenting the development of the second generation (primarily the NAV 5000) handheld GPS unit produced by Magellan. The NAV 5000 used five channels working simultaneously to locate and collect data from GPS satellites. The units GaAs circuitry rapidly processed the data received from the satellites to compute current location, altitude, velocity and navigation in under one minute. The NAV 5000 was designed primarily for marine use. Other second generation products included: OEM Brain, OEM 1/2 Brain, Nav 500 Pro, NAV 100M5, Skaynav, Fieldpro, NAV 5200 PM, NAV 5000A, NAV 5000D, DX, DLX, Pro mark V, and the Map 7000.

Subseries 7, Third Generation, 1986-1994, consists of technical notes for the development of the third generation (primarily Meridian and Trailblazer models) of Magellan GPS devices. Third generation models were intended for the lower end of the GPS market and were compact hand-held (size, weight, battery life) and a retail price that was reasonable. Other third generation devices included: the meridian, Trailblazer, AIV10 OEM, Skatblazer, NAV 6500 PM, Meridian/TB/SB XL, NAV 1200 Pm, NAV 1200 XL PM, NAV DLX 10, Promark X, and the Pro Mark X-CM.

Subseries 8, Swiss Army Chip (SAC) Development, 1987-1995, consists of technical notes, diagrams and drawings, and specifications for the development of a digital chip used in Magellan GPS products. Don Rea and Norm Hunt of Magellan are credited with naming the chip. The chip combined several elements--GPS DPS channels, correalators, real time clock, alarm timer, interval timer, keyboard interface, display interface, precise timing, power sequencing, memory decoding, code generators, and beeper driver, to name a few--which allowed the development team reduce the overall power, size, and cost of the chip. Magellan outsourced the manufacture of the SAC.

Subseries 9, Technical Products Development Seminars, 1997-1998, consists of documentation for nine seminars in a series of technology seminars initiated by the product develpment group at Magellan. The seminars were created to keep all staff up to date on past, present, and future technology developments at Magellan. The nine seminars cover the history of Magellan GPS technology and address specific areas of development such as antennas, circuits, signal processing, software, navigation needs, and radio frequency. Other information includes tables providing comparisons for the first, second, and third generations, timelines, SAC chip characteristics, and product shipping dates. The seminars provide a good foundation for understanding what the product development staff accomplished. Researchers should consult Series 8 which documents some of the technical seminars.

Subseries 10, Specifications, 1992-1994, consists of preliminary, functional, and system requirements describing technical characteristics for several Magellan products.

Subseries 11, TriQuint Semiconductor Materials, 1986-1992, consists of materials documenting TriQuint Semiconductor, Inc.'s work. TriQuint was a division of Tektroninix, Inc., a manufacturer of analog and mixed signal gallium arsenide (GaAs) integrated circuit products. TriQuint supplied custom radio frequency (RF) and Gallium arsenide (GaAs) chips for Magellan's hand-held GPS systems and tested its chips. Documentation includes trip summaries and observations to TriQuint by Don Rea, a Magellan engineer as well as technical drawings, memorandums, development schedules, invoices, purchase orders, and tests results, production quantity and costs, and specifications. In 1986, Don Rea met Gary Barta, then principal engineer at TriQuint through his frequent visits to the company. Barta led the engineeering development of the an integrated circuit which combined the GPS L-band low-noise pre-amplifier, UHF local oscillator, down converter and high speed digital divisers on a single gallium-arsenide chip. Nothing like this had been done before for a cost senstive commerical application. Barta later joined Magellan in November 1988 as Vice President of Engineering and made the chip he had designed actually work in the environment of a hand-held product.

Series 4, Marketing and Promotional Materials, 1985-1997, is divided into six subseries: Subseries 1, Market Research, 1985-1993 and undated; Subseries 2, Product Literature, circa 1990s; Subseries 3, Advertisements, 1988-1995 and undated; Subseries 4, Press Releases, 1988-1996; Subseries 5, Presentation Materials, 1990-[1997?] and undated; and Subseries 6, Newspaper and Magazine Clippings, 1988-1996 and undated.

Biographical / Historical:
Ed Tuck of the Boundary Fund, a venture capital firm specializing in technologies founded the Magellan Systems Corporation in 1986 and served as its director from 1986 to 1993. Tuck assembled the initial team of Norm Hunt, Larry Weill, Val Wong, and Sab Ifune to conduct a feasibility study in early 1986 to pursue commercial markets for products based on global positioning system (GPS) technology. Magellan introduced the first handheld commercial GPS receiver in 1989 and was the first company to make GPS devices affordable to consumers. Magellan introduced the first handheld commercial GPS receiver in 1989 and was the first company to make GPS devices affordable to consumers. The company successfully introduced GPS products into the marine, professional, military and automotive and general aviation markets.

The Global Positioning System (GPS) began as a United States Department of Defense Program in the 1960s with a navy system known as Transit (first satellite navigation system). Two other projects soon followed, Timation (satellite to broadcast accurate time reference) and Air Force Project 612B, which began in the 1970s. In 1973, the development of the Navigation Signal Timing and Ranging Global Positioning System (NAVSTAR) began under the management of the Air Force. Designed by the military, the system provided twenty-four positioning satellites under all- weather conditions using passive (non-transmitting) receivers. This kept a user's presence from being detected as a result of the receiver. Although primarily for military use, the system also offered a less-precise coded signal for civilian use.

GPS uses a group of twenty-four earth-orbiting satellites which broadcast continuously. The data being broadcast can be processed by a portable receiver to determine a user's position, velocity and time. GPS has three parts: 1) space part with twenty-four satellites; 2) ground part with monitor and 3) user part with receivers that process the signals and calculate position.

In the spring of 1986, the Magellan team published a specification for a custom mixed signal RF (radio frequency) integrated circuit and by fall 1986, had a breadboard (used in prototyping of electronics) and began software development and testing. Magellan focused its research, product engineering, and design activities on the development of GPS receivers that were application-specific, software-intensive, reliable, lower power, easy to use, and affordable.

From 1986 to 1988, the Boundary Fund provided the venture capital for feasibility studies and the initital product design. By 1988, the company occupied its first stand-alone facility in Monrovia, California with thirty-five employees. In May 1989, the company's first product, the NAV 1000, shipped, and in that same year, the company entered the military market with the NAV 1000M. The company entered the professional market in January 1990 with the NAV 1000 PRO, the world's first hand-held GPS product. By 1991, Magellan moved to a new facility in Dimas, California and introduced advanced five-channel technology. It also incorporated in the United Kingdom (UK) as Magellan Systems to handle product distribution in the rest of the UK and Europe.

The SkyNAV 5000 was introduced in 1992 for the general aviation market, and in the same year, hand-held differential GPS technology for the marine market appeared. Magellan was purchased by Orbital Sciences Corporation in 1994. In 2001, Thales Group purchased the Magellan division of Orbital Sciences, and the company became known as Thales Navigation. In 2006, a private equity firm, Shah Capital Partners, and other investors purchased Thales Navigation, and the company was officially renamed Magellan Navigation. Magellan (also known as MiTAC Digital Corporation) is a wholly-owned subsidiary of MiTAC International Corporation and promotes and sells products and services under the Magellan brand name. Magellan is headquartered in Santa Clara, California.
