Biographical / Historical:
Since its founding in 1913, the history of the Formica Company has been marked by a spirit of innovation and entrepreneurship. The history begins with the discovery of Formica by two men who envisioned the plastic laminate as breakthrough insulation for motors. Later, Formica became a ubiquitous surfacing material used by artists and architects of post-modern design. The various applications of the plastic laminate during the twentieth century give it a prominent role in the history of plastics, American consumerism, and American popular culture.
The Formica Company was the brainchild of Herbert A. Faber and Daniel J. O'Conor, who met in 1907 while both were working at Westinghouse in East Pittsburgh, Pennsylvania. O'Conor, head of the process section in the Research Engineering Department, had been experimenting with resins, cloth, paper, and a wide array of solvents in an effort to perfect a process for making rigid laminate sheets from Kraft paper and liquid Bakelite. O'Conor produced the first laminate sheet at Westinghouse by winding and coating paper on a mandrel, slitting the resulting tube, and flattening it on a press. The finished product was a laminated sheet with the chemical and electrical properties of Bakelite that were cut into various shapes and sizes. O'Conor applied for a patent on February 1, 1913, but it was not issued until November 12, 1918 (US Patent 1,284,432). Since the research was done on behalf of Westinghouse, the company was assigned the patent, and O'Conor was given one dollar, the customary amount that Westinghouse paid for the rights to employees' inventions.
Herbert Faber, Technical Sales Manager of insulating materials, was excited about O'Conor's discovery. Faber saw limitless possibilities for the new material. However, he quickly became frustrated by Westinghouse's policy limiting the sale of the laminate to its licensed distributors. After failing to persuade Westinghouse to form a division to manufacture and market the new material, Faber and O'Conor created their own company. On May 2, 1913, the first Formica plant opened in Cincinnati, Ohio. On October 15, 1913, the business incorporated as the Formica Insulation Company with Faber as president and treasurer and O'Conor as vice-president and secretary. The company began producing insulation parts used in place of or "for mica," the costly mineral that had been used in electrical insulation.
Like most new companies, Formica had modest beginnings. Faber and O'Conor faced the challenge of looking for investors who would let them maintain control over the company. Finally, they met J. G. Tomluin, a lawyer and banker from Walton, Kentucky, who invested $7,500 for a one-third share in the Formica Company. Renting a small space in downtown Cincinnati, Faber and O'Conor began work. The company's equipment list consisted of a 35-horsepower boiler, a small gas stove, and a variety of homemade hand screw presses. By September 1913, Tomluin had brought in two more partners, David Wallace and John L. Vest. With the added capital, O'Conor, Faber, and Formica's eighteen employees began producing automobile insulation parts for Bell Electric Motor, Allis Chalmers, and Northwest Electric.
Initially, the Formica Company only made insulation rings and tubes for motors. However, by July 4, 1914, the company obtained its first press and began to produce flat laminate sheets made from Redmenol resin. Business gradually grew, and by 1917 sales totaled $75,000. Fueled by World War I, Formica's business expanded to making radio parts, aircraft pulleys, and timing gears for the burgeoning motor industry. In the years that followed, Formica products were in high demand as laminate plastics replaced older materials in washers, vacuum cleaners, and refrigerators. By 1919, the Formica Company required larger facilities and purchased a factory in Cincinnati.
During this time, patent battles and legal suits emerged to challenge Formica's success. On June 11, 1919, Westinghouse sued Formica for patent infringement on its laminated gears; Formica won. Later that year, Westinghouse brought two new lawsuits against Formica. The first was for a patent infringement on the production of tubes, rods, and molded parts; the second was over an infringement based on a 1913 patent assigned to Westinghouse through O'Conor. Formica prevailed in both suits.
Legal battles did not deter the company. Having to defend itself against a giant corporation gave Formica a reputation as a scrappy contender. Finally, Faber and O'Conor made a quantum leap in 1927, when the company was granted a U.S. patent for a phenolic laminate utilizing lithographed wood grains of light color, forming an opaque barrier sheet which blocks out the dark interior of the laminate. In 1931, the company received two more patents for the preparation of the first all paper based laminate and for the addition of a layer of aluminum foil between the core and the surface, making the laminate cigarette-proof. These patents would allow Formica to move from a company dealing primarily with industrial material to the highly visible arena of consumer goods.
In 1937, Faber had a severe heart attack which limited his activity within the company. O'Conor continued as president, encouraging new product lines, including Realwood, as a laminate with genuine wood veneer mounted on a paper lamination with a heat-reactive binder. With the introduction of Realwood and its derivatives, manufacturers started
using Formica laminate for tabletops, desks, and dinette sets. By the early forties, sales of Formica laminate were over 15 million dollars. The final recipe for decorative laminate was perfected in 1938, when melamine resins were introduced. Melamine was clear, extremely hard, and resistant to stains, heat, light, less expensive than phenolic resins. It also made possible laminates of colored papers and patterns.
Due to World War II, Formica postponed the manufacturing of decorative laminate sheets. Instead, the company made a variety of war-time products ranging from airplane propellers to bomb buster tubes.
The post-World War II building boom fueled the decorative laminate market and ushered in what would come to be known as the golden age for Formica. The company, anticipating the demand for laminate, acquired a giant press capable of producing sheets measuring thirty by ninety-six inches for kitchen countertops. Between 1947 and 1950, more than 2 million new homes were designed with Formica brand laminate for kitchens and bathrooms.
Formica's advertising campaigns, initially aimed at industry, were transformed to speak to the new decorative needs of consumer society, in particular the American housewife. Formica hired design consultants, Brooks Stevens, and, later, Raymond Loewy who launched extensive advertising campaigns. Advertising themes of durability, cleanliness, efficiency, and beauty abound in promotional material of this time. Advertisers promised that the plastic laminate, known as "the wipe clean wonder," was resistant to dirt, juices, jams, alcohol stains, and cigarette burns. Atomic patterns and space-age colors, including Moonglo, Skylark, and Sequina, were introduced in homes, schools, offices, hospitals, diners, and restaurants across America.
The post-war period was also marked by expansion, specifically with the establishment of Formica's first international markets. In 1947, Formica signed a licensing agreement with the British firm the De La Rue Company of London for the exclusive manufacture and marketing of decorative laminates outside North America, and in South America and the Pacific Basin. In 1948, Formica changed its name from the Formica Insulation Company to the Formica Company. In 1951, Formica responded to growing consumer demand by opening a million square foot plant in Evendale, Ohio, devoted to the exclusive production of decorative sheet material. In 1956, the Formica Company became the Formica Corporation, a subsidiary of American Cyanamid Company. A year later, the international subsidiaries that Formica formed with De La Rue Company of London were replaced by a joint company called Formica International Limited.
The plastic laminate was not merely confined to tabletops and dinette sets. Formica laminate was used for skis, globes, and murals. Moreover, well-known artists and architects used the decorative laminate for modernist furniture and Art Deco interiors. In 1960, Formica's Research and Development Design Center was established, adjacent to the Evendale plant, to develop uses for existing laminate products. In 1966, the company
opened the Sierra Plant near Sacramento, California. Such corporate expansion enabled Formica to market its laminates beyond the traditional role as a countertop surface material.
In 1974, Formica established its Design Advisory Board (DAB), a group of leading designers and architects. DAB introduced new colors and patterns of laminate that gained popularity among artists and interior designers in the 1980s. In 1981, DAB introduced the Color Grid, a systematic organization of Formica laminate arranged by neutrals and chromatics. The Color Grid was described as the first and only logically arranged collection of color in the laminate industry. DAB also developed the Design Concepts Collection of premium solid and patterned laminates to serve the needs of contemporary interior designers.
In the 1980s and 1990s, the corporation continued to produce laminates for interior designers, artists, and architects. In 1982, Formica introduced COLORCORE, the first solid-color laminate. Due to its relatively seamless appearance, COLORCORE was adopted by artists for use in furniture, jewelry, and interior design. The introduction of COLORCORE also marked the emergence of a wide variety of design exhibitions and competitions sponsored by the Formica Corporation. In 1985, Formica Corporation became independent and privately held. Formica continues to be one of the leading laminate producers in the world with factories in the United States, England, France, Spain, Canada, and Taiwan.

Biography of William J. Hammer:
William Joseph Hammer, assistant to Thomas Edison and a consulting electrical engineer, was born at Cressona, Schuylkill County, Pennsylvania, February 26, 1858, and died March 24, 1934. His parents were Martha Augusta Bech (1827-1861) and William Alexander Hammer (1827-1895). He attended private and public schools in Newark, New Jersey, and university and technical school lectures abroad.
On January 3, 1894, Hammer married Alice Maud White in Cleveland, Ohio. They had one daughter, Mabel (Mrs. Thomas Cleveland Asheton). Alice Hammer died in 1906.
In 1878 Hammer became an assistant to Edward Weston of the Weston Malleable Nickel Company. In December 1879 he began his duties as laboratory assistant to Thomas Edison at Menlo Park, New Jersey. He assisted in experiments on the telephone, phonograph, electric railway, ore separator, electric lighting, and other developing inventions. However, he worked primarily on the incandescent electric lamp and was put in charge of tests and records on that device. In 1880 he was appointed Chief Engineer of the Edison Lamp Works. In this first year, the plant under general manager Francis Upton, turned out 50,000 lamps. According to Edison, Hammer was "a pioneer of Incandescent Electric Lighting"! (Hammer's memoranda and notes, Series 2).
In 1881 Edison sent Hammer to London as Chief Engineer of the English Electric Light Co. In association with E. H. Johnson, general manager, Hammer constructed the Holborn Viaduct Central Electric Light Station in London. This plant included three, thirty-ton "Jumbo" steam-powered dynamos (generators), and operated 3,000 incandescent lamps. Holborn was the first central station ever constructed for incandescent electric lighting. Hammer began its operation on January 12, 1882, by lighting the Holborn Viaduct.
In 1882 Hammer also installed a large isolated lighting plant containing twelve Edison dynamos at the Crystal Palace Electric Exposition and the Edison Exhibit at the Paris Electrical Exposition.
At this time Hammer also designed and built the first electric sign. The sign spelled the name "Edison" in electric lights, and was operated by a hand controlled commutator and a large lever snap switch. It was erected over the organ in the Crystal Palace concert hall.
In 1883 Hammer became Chief Engineer for the German Edison Company (Deutsche Edison Gesellschaft), later known as Allegemeine Elektricitaets Gesellschaft. Hammer laid out and supervised the installations of all Edison plants in Germany. While in Berlin he invented the automatic motor-driven "flashing" electric lamp sign. The sign, which flashed "Edison" letter by letter and as a whole, was placed on the Edison Pavilion at the Berlin Health Exposition in 1883.
On his return to the United States in 1884, Hammer took charge of some of Edison's exhibits, including Edison's personal exhibit, at the International Electrical Exhibition held under the authority of the Franklin Institute in Philadelphia. There he built the first flashing "Column of Light." He also became confidential assistant to E. R. Johnson, president of the parent Edison Electric Light Company. Together with Johnson and Frank J. Sprague, he became an incorporator of the Sprague Electric Railway and Motor company. He also was elected a trustee and the company's first secretary.
Hammer installed an all-electric house at Newark, New Jersey in 1884 and he devised various electrical devices and contrivances for an unusual party for friends and colleagues. (See "Electrical Diablerie" beginning on page 6).
At the end of 1884 Hammer became chief inspector of central stations of the parent Edison Electric Light Company. For over two years he made financial, mechanical, and electrical reports on the various stations throughout the United States. During 1886-87 he was chief engineer and general manager of the Boston Edison Electric Illuminating Company. He also acted as contractor for the company. He laid $140,000 of underground tubing and installed Sprague Electric Motors.
In 1888, acting as an independent engineer, he was placed in charge of completing the 8,000 light plant of the Ponce de Leon Hotel in St.Augustine Florida. At the time this was the largest isolated incandescent lighting plant ever constructed. Also in 1888 Hammer was appointed consulting electrical engineer to the Cincinati Centennial Expostition, and as a contractor designed and installed over $40,000 worth of electrical effects.
Hammer was appointed Edison's personal representative remarked, "There are a lot of crowned heads in the Edison business. How many of them am I subservient to?" Mr. Edison answered "You take no instructions except from Thomas A. Edison." Hammer asked "What are your instructions?" Mr. Edison replied, 'Hammer, I haven't any. Go and make a success of it.' In Paris he set up and operated all of Edison's inventions, which embraced nineteen departments and covered 9,800 square feet of space. He also built a huge Edison lamp forty-five feet high employing 20,000 lamps. Edison remarked, 'He had entire charge of my exhibit at the Paris Exposition, which was very successful." This was the largest individual exhibit at the Exposition, costing $100,000. Mr. Edison replied, "I want you to go right out and have a card engraved William J. Hammer, Representative of Thomas A. Edison. You are the only representative I have here," and he complimented him on his work adding, "The French government will do something handsome for you for your work." Hammer replied that he would not raise his hand to get it and did not believe in giving such honors to people who seek them. Mr. Edison said, "You are wrong. You are a young man and such things are valuable. At any rate if there's anyone in this exhibition who deserves recognition, you do, and I'm going to see you get it' (Hammer's memoranda and notes, Series 2). Thirty-four years later, in 1925, through the personal influence of Edison, Hammer was made Chevalier of the Legion of Honor by the French government.
In 1890 Hammer returned to the United States and opened an office as a consulting electrical engineer. He was in private practice until 1925, making reports, conducting tests, and giving expert testimony in patent suits.
On January 31, 1890, Hammer formed the Franklin Experimental Club of Newark where boys could come and carry on experiments, build apparatus, and listen to lectures. Hammer equipped the laboratory at his own expense. One side was an electrical laboratory and the other a chemical laboratory. About forty-five boys joined. Each boy had a key to the club and a section of a bench with his own drawer for keeping notes, tools, and other equipment. In 1892 the structure was destroyed by fire from a saloon next door, ending Hammer's plans for a large and useful institution.
In 1896 Hammer was elected president of the National Conference of Standard Electrical Rules, which prepared and promulgated the "National Electric Code."
In 1902 in Paris, Hammer visited Pierre and Marie Curie, the discoverers of radium and polonium. They gave him nine tubes of radium and one of polonium to bring back to the United States. He also acquired some sulphide of zinc, with which he mixed radium carbonates, producing a beautifully luminous powder. This was the first radium-luminous material ever made. By mixing the powder with Damar varnish he produced the first radium-luminous paint. He was also the first person to make colored (and white) luminous materials. In 1907 he invented and patented a process for producing colored phosphorescent materials by combining phosphorescent and fluorescent substances.
Back in the United States in the fall of 1902 and into 1903, Hammer applied his radium-luminous materials to thirty different objects: luminous dials for clocks and watches, toys, artificial flowers, radium luminous gun sights, taps and pulls for lamp sockets, switches, keyholes, push buttons, telephone transmitters, poison bottle labels, a small plaster figure, push pins, and writing implements among others. He did not patent the invention due to the scarcity and high cost of radium, but later in an important suit involving foreign and American patents of radium-luminous materials, his testimony and that of other noted scientists and professionals of the day who had visited his home and laboratory proved that his work completely anticipated that of all inventors both in the United States and abroad. In 1902 he was one of the first persons to be burned with radium.
Hammer gave eighty-eight lectures on the Curies' work and on radium and radioactive substances. He wrote the first book published on radium, Radium and other Radioactive Substances, 1903. Hammer proposed and used radium for cancer and tumor treatment, successfully treating and curing a tumor on his own hand in July 1903. Tie also supplied several hospitals with radioactive water he had made and conducted extensive experiments with x-rays, cathode-rays, radium-rays, ultraviolet lights, phosphorescence, fluorescence, and cold-light. He was probably the first to suggest many wartime uses for radium-luminous materials, such as airplanes, instruments, markers, barbed-wire, and landing fields.
Hammer also did important work with selenium, a nonmetallic element that resembles sulphur and tellurium chemically. It is obtained chiefly as a by-product in copper refining, and occurs in allotropic forms. A grey stable form varies in electrical conductivity depending on the intensity of its illumination and is used in electronic devices. Hammer invented selenium cells and apparatus, and suggested industrial uses for selenium and other light-sensitive cells.
In 1886 Hammer devised a system for automatically controlling street and other lights by use of a selenium cell. In 1892 he designed a torpedo that could be steered by searchlight and selenium cell. In the early 1900s he suggested many other uses for "light" cells, including burglar alarms, dynamo control, buoy, railroad signaling, automatic gun firing, transmission of music, stethoscope recorder, automatic operating shutters, automatic boiler feed, snow recorder, and electric motor control.
At the St. Louis Exposition of 1904 Hammer was Chairman of the Jury for Telegraphy, Telephony, and Wireless. He was also a member of the "Departmental" Jury ("Applied Science: Electricity") and of the committee appointed to organize the International Electrical Congress at St. Louis in 1904.
In 1906 Hammer received the "Elliott Cresson" gold medal from the Franklin Institute for his "Historical Collection of Incandescent Electric Lamps," accumulated over thirty-four years. This collection received a special silver medal at the International Electrical Exposition at the Crystal Palace, London, England, in 1882, and "the Grand Prize" at the St. Louis Exposition of 1904.
During the First World war Hammer served as a major on the General Staff of the, Army War College, Washington, D.C., where he was attached to the Inventions Section of the War Plans Division and later to the operations Division at the war Department in charge of electrical and aeronautical war inventions. He did special work at the U.S. Patent office, marking and delaying patents that might be useful to the enemy and served on the Advisory Board of Experts attached to the Alien Property Commission. He was elected Historian general of the Military order of the World War (1926-1928) and was a member of the Society of American Military Engineers.
Hammer was an early aeronautics enthusiast and became the owner of one of the first airplanes sold in the United States to an individual. Even in his last few years of his life, Hammer's interest in airplanes did not wane. In 1931, by the permission of the Secretary of the -Navy, Hammer made a twelve-hour flight in the Los Angeles dirigible from the Lakehurst, New Jersey airdrome along the coast of the Atlantic Ocean to New York, flying over New York City at night.
Hammer served on numerous committees. In 1916 he was a member of a special committee, appointed by the Aeronautical Society of America. one of his responsibilities on this committee was to recommend methods for the formation of a reserve force of civilian aviators for the Army. At the start of World War I, Hammer was appointed chairman of a committee on camouflage by the Aeronautical Society. During the war, he flew airplanes and tested sound devices and was also among the first five selected out of thousands for the dissemination of propaganda into many countries. He also examined documents and papers captured from spies and prisoners of war to see if these material contained any technical matter of value to the U. S. Army.
Hammer traveled extensively as a delegate of the Military Order of World War I. For example, in 1922 he attended the aeronautical Congress and Flying Meet in Detroit, Michigan. In the same year he also attended Immigration Conferences of the National Civic Federation in New York.
Between 1922 and 1928 Hammer intensified his efforts in collecting and organizing autographed portraits of eminent scientific men, a project he had been working on for over forty-five years. Tie displayed many of these portraits with his Historical Collection of Incandescent Electrical Lamps in -his New York home. At this time he also prepared an elaborate bibliography on selenium and its industrial and scientific applications.
Major William Joseph Hammer, described by Edison as "my most valuable assistant at Menlo Park" died of pneumonia March 24, 1934.
'Electrical Diablerie':
"ELECTRICAL DIABLERIE"
N.Y. World, January 3, 1885 and Newark, N.J. Daily Advertiser and Journal, January 3, 1885
Some years ago, (1884) on New Year's eve, an entertainment was given at the home of Mr. William J. Hammer, in Newark, N.J., which, for the display of the powers of electricity has seldom, if ever, been equaled. Mr. Hammer, who has for years been associated with Mr. Edison, both in this country and in Europe, desiring to give his old classmates, the "Society of Seventy-Seven," a lively and interesting time, invited them to "an electrical dinner" at his home.
The invitations which were sent out were written upon Western Union telegram blanks with an Edison electric pen. When the guests arrived and entered the gate, the house appeared dark, but as they placed foot upon the lower step of the veranda a row of tiny electric lights over the door blazed out, and the number of the house appeared in bright relief. The next step taken rang the front door bell automatically, the third threw open the door, and at the same time made a connection which lit the gas in the hall by electricity.
Upon entering the house the visitor was invited to divest himself of his coat and hat, and by placing his foot upon an odd little foot-rest near the door, and pressing a pear-shaped pendant hanging from the wall by a silken cord, revolving brushes attached to an electric motor brushed the mud and snow from his shoes and polished them by electricity. As he was about to let go of the switch or button, a contact in it connected with a shocking coil, caused him to drop it like a hot potato. Up-stairs was a bedroom which would be a fortune to a lazy man; he had only to step on the door sill and the gas was instantly lighted. The ceiling was found to be covered with luminous stars, arranged to represent the principal constellations in the heavens-while comets, moons, etc., shone beautifully in the dark. By placing one's head on the pillow, the gas, fifteen feet away, would be extinguished and the phosphorescent stars on the ceiling would shine forth weirdly, and a phosphorescent moon rose from behind a cloud over the mantel and slowly describing a huge arch disappeared behind a bank of phosphorescent clouds on the other side of the room; by pressing the toe to the foot-board of the bed the gas could again be relit.
Pouring a teacup of water into the water clock on the mantel and setting the indicator would assure the awakening of the sleeper at whatever hour he might desire. There was also in the hall outside the room a large drum, which could be set to beat by electricity at the hour when the family wished to arise. The whole house was fitted throughout with electric bells, burglar alarms, fire alarms, telephones, electric cigar lighters, medical coils, phonographs, electric fans, thermostats, heat regulating devices, some seven musical instruments, operated by electricity, etc.
Upon the evening referred to nearly every. piece of furniture in the parlor was arranged to play its part. Sit on one chair and out went the gas, take another seat and it would light again; sitting on an ottoman produced a mysterious rapping under the floor; pressure on some chairs started off drums, triangles, tambourines, cymbals, chimes and other musical instruments; in fact, it seemed unsafe to sit down anywhere. The quests stood about in groups and whispered, each hoping to see his neighbor or a new comer caught napping.
One visitor (Brown) secured an apparently safe seat, and was telling a funny story--he had left electricity far behind--but just as he reached the climax, a pretty funnel-shaped Japanese affair like a big dunce cap, that seemed but a ceiling ornament which was held in place by an electromagnet, dropped from overhead and quietly covered him up, thus silently extinguishing the story and the story-teller.
A big easy chair placed invitingly between the folding doors joining the double, parlors sent the unwary sitter flying out of its recesses by the sudden deafening clamor of twenty-one electric bells hidden in the folds of the draperies hanging in the doorway. In a convenient position stood the silver lemonade pitcher and cup, the former was filled with the tempting beverage, but no matter how much a guest might desire to imbibe one touch convinced him that the pitcher and cup were so heavily charged with electricity as to render it impossible for him to pour out a drink or even to let go until the electricity was switched off from the hidden induction coil.
Some one proposed music, and half a selection had been enjoyed when something seemed to give way inside the piano, and suddenly there emanated from that bewitched instrument a conglomeration of sounds that drowned the voices of the singers, and the keys seemed to beat upon a horrible jangle of drums, gongs and various noise-producing implements which were fastened inside of and underneath the piano.
After the guest were treated to a beautiful display of electrical experiments, under the direction of Mr. Hammer, and Professor George C. Sonn, they were escorted to the dining-room, where an electrical dinner had been prepared and was presided over by 'Jupiter," who was in full dress, and sat at the head of the table, where by means of a small phonograph inside of his anatomy he shouted, "Welcome, society of Seventy-Seven and their friends to Jove's festive board." The menu was as follows: "Electric Toast," "Wizard Pie," "Sheol Pudding," "Magnetic Cake," "Telegraph Cake," "Telephone Pie," "Ohm-made Electric Current Pie," "Menlo Park Fruit," "Incandescent Lemonade," "'Electric Coffee" and "Cigars," etc., and music by Prof. Mephistopheles' Electric Orchestra.
About the table were pretty bouquets, and among the flowers shone tiny incandescent lamps, while near the center of the table was placed an electric fan which kept the air cool and pure, and at each end was a tiny Christmas tree lighted with small incandescent lamps, planted in a huge dish of assorted nuts and raisins. Each lamp had a dainty piece of ribbon attached to it upon which the initials of the Society and the date were printed, and each guest received a lamp to take away with him as a souvenir of the occasion. Plates of iced cakes made in the form of telephones, switches, bells, electric lamps, batteries, etc., stood on each side of the center piece.
Promptly at 12 o'clock, as the chimes of the distant churches came softly to the ears of the assembled quests, pandemonium seemed to change places with the modest dining-room. A cannon on the porch, just outside the door, and another inside the chimney, were unexpectedly discharged; and at this sudden roar, every man sprang back from the table; the lights disappeared; huge fire-gongs, under each chair beat a tattoo. The concussion produced by the cannon in the fireplace caused several bricks to come crashing down the chimney, and as the year of 1884 faded away, the table seemed bewitched. The "Sheol Pudding" blazed forth green and red flames illuminating the room, tiny tin boxes containing 'Greek" fire which had been placed over each window and door were electrically ignited by spirals of platinum iridium wire heated by a storage battery and blazed up suddenly; the "Telegraph Cake" clicked forth messages said to be press reports of the proceedings (it was also utilized to count the guests and click off the answers to various questions put to it); bells rang inside the pastry; incandescent lamps burned underneath the colored lemonade; the thunderbolt pudding discharged its long black bolts all over the room (long steel spiral springs covered with black cloth) and loud spirit rapping occurred under the table. The silver knives, forks and spoons were charged with electricity from a shocking coil and could not be touched, while the coffee and toast (made by electricity) were made rapidly absorbed; the "Magnetic Cake' disappeared; the "Wizard" and "Current Pies' vanished, and 'Jupiter" raising a glass to his lips began to imbibe.
The effect was astonishing! The gas instantly went out, a gigantic skeleton painted with luminous paint appeared and paraded about the room, while Jupiter's nose assumed the color of a genuine toper! His green eyes twinkled, the electric diamonds in his shirt front (tiny lamps) blazed forth and twinkled like stars, as he phonographically shouted "Happy New Year'. Happy New Year!" This "Master of Cererionies' now becoming more gentle, the guests turned their attention to the beautiful fruit piece, over four feet high, that stood in the center of the table. From the fruit hung tiny electric lamps, and the whole was surmounted by a bronze figure of Bartholdils "Statue of Liberty;" uplifted in "Miss Liberty's" right hand burned an Edison lamp no larger than a bean.
The dinner finished, and there was much that was good to eat, notwithstanding the "magical" dishes which they were first invited to partake of, speeches were delivered by Messrs. Hammer, Rutan, McDougall, 'Brown, Duneka, and Dawson, and an original poem was read by Mr. Van Wyck. Upon repairing to the parlors the guest saw Mr. Hammer's little sister, May, dressed in white and mounted upon a pedestal, representing the "Goddess of Electricity:" tiny electric lamps hung in her hair, and were also suspended as earrings, while she held a wand surmounted by a star, and containing a very small electric lamp.
Not the least interesting display of electricity took place in front of the house, where a fine display of bombs, rockets, Roman candles, Greek fire and other fireworks were set off by electricity, which was by the way, the first time this had been accomplished. The guests were requested to press button switches ranged along the front veranda railing thus causing electricity from a storage battery to heat to a red heat tiny platinum iridium spirals attached to each fuse of the various pieces of fireworks thus sending up rocket after rocket, as well as igniting the other pieces which had been placed in the roadway in front of the house.
An attempt was made to send up a large hot air balloon to which was attached a tiny storage battery and an incandescent signal lamp but a sudden gust of wind caused the ballon to take fire as it rose fr(xn the ground. This constituted the only experiment made during the evening which was not an unqualified success. The innumerable electrical devices shown during the progress of the dinner were all operated by Mr. Hammer, who controlled various switches fastened to the under side of the table and attached to a switchboard, which rested on his lap, while the two cannons were fired by lever switches on the floor, which he operated by the pressure of the foot. Electricity was supplied by primary and storage batteries placed under the table. After an exhibition of electrical apparatus and experiments with a large phonograph, the guests departed with a bewildered feeling that somehow they had been living half a century ahead of the new year."
Expositions and Exhibitions:
The many Expositions held at the end of the 19th and the beginning of the 20th centuries were important for the Edison Electric Company's future business. In particular the Paris Electrical Exposition, 1881, and the Crystal Palace Exposition in London in 1892 were introductions for the company's international business enterprises. Edison, therefore, sent his ablest men from the Menlo Park staff (Batchelor, Hammer, Jehl, Johnson) to Europe to oversee the installation and promotion of the company's exhibits.
THE INTERNATIONAL PARIS EXPOSITION OF 1881
The International Paris Electrical Exposition was held during the summer of 1881. Many of Edison's electric lighting systems, ranging from arc lights to incandescent devices, were exhibited. A model of the Edison central-station lighting system showed an arrangement of incandescent lights within a complete electrical distributing system, including novel appliances and controls of the Edison system. "The completeness of its conception made a profound impression on the foremost European electrical engineers of that era." (Josephson, Matthew. Edison, A Biography. p. 252). Edison also exhibited his first "Jumbon generator. It was "direct-connected" to its driving engine, another area in which Edison pioneered. Edison improved upon the original design of William Wallace's "Telemachon' - a generator coupled to a water-powered turbine. Wallace had earlier in the decade produced the first dynamo in America.
Charles Batchelor headed the Edison exhibits within Paris. Edison received many gold medals and diplomas and was awarded the ribbon of the Legion of Honor.
The William J. Hammer Collection contains various reports and catalogues exhibited at the International Exposition of Electricity. (Series 3, Box 44, Folders 1-4)
THE CRYSTAL PALACE EXHIBITION OF 1882
At the Crystal Palace Exhibition of 1882 in London, Edison displayed a great many of his inventions, including: the steam dynamo; specimens of street pipes and service boxes used in the Edison underground system of conductors, and the system of house conductors with devices for preventing abnormal increase of energy in house circuits; apparatus for measuring the resistance of his lamps, for measuring the energy consumed in lamps, and rheostats for restoring currents; also thermogalvano-meters, carbon rheostats, dynamometers, photometers, carbon regulators, Weber meters,, current regulators, and circuit breakers for controlling electric light circuits; the carbon relay, the pressure relay, and the expansion relay; the telegraph system in Morse characters; and the Roman character automatic telegraph.
Thomas Edison also exhibited the carbon telephone, the musical telephonograph, telephone repeater, and numerous apparatus for demonstrating the method of varying the resistance of a closed circuit by contact with carbon, illustrative of the experimental factors of the Edison carbon transmitter. Incandescent lamps, the process of the manufacture of lamps, and various designs of electric light chandeliers were also on display.
Hammer won the silver medal at the exposition for the first complete development of the incandescent electric lamp from its initial stages to date. At the exhibition the first hand-operated flashing electric lamp sign was displayed, which was invented and built by Hammer.
The collection contains photographs of the Edison dynamo, and the Edison Electric Lighting Plant of 1882 erected by Hammer. The official Catalogue of the International Electric and Gas Exhibition, and various articles from the Daily Telegraph, Daily Chronicle, and Daily News are also included within the collection (Series 4, Box 99 and Series 3, Box 42, Folder 1-2).
THE BERLIN EXPOSITION OF 1883.
The Berlin Exposition of 1883 had the first motored flashing electric sign designed, built and operated by Hammer. The electric sign spelled out the word "Edison" letter by letter and was used on the Edison pavilion in the Health Exposition. It has most features of today's flashing sign.
The collection contains two photographs of the first flashing sign (Series 4, Box 99).
THE FRANKLIN INSTITUTE INTERNATIONAL ELECTRICAL EXHIBITION OF 1884
The Franklin Institute International Electrical Exhibition was held in Philadelphia from September 2 to October 14, 1884. Many of Edison's companies had display booths at the exhibition. The Edison Electric Light Company showed in operation their system of house lighting as supplied from a central station. The Edison Company for Isolated Lighting exhibited their system of lighting factories, hotels, hospitals, and other places situated beyond the reach of a central lighting station. A full assortment of Edison lamps and dynamos also made up parts of other exhibits. Also displayed at the exhibition was the first flashing column of light, which Hammer designed and built.
Included within the collection are a variety of photographs of the exhibitions. Four pamphlets also are contained in the collection (Series 3, Box 1, Folder 3), (Series 4, Box 99).
THE EXPOSITION OF THE OHIO VALLEY AND THE CENTRAL STATES OF 1888
The Exposition of the Ohio Valley and Central States, in Cincinnati from July 4 to October 27, was in honor of the one hundredth anniversary of the settlement of Cincinnati. The exposition showed the progress and ramifications of the first hundred years of this settlement.
The space occupied by permanent buildings was greater than that covered by any building for exhibiting purposes on the Western continent. T',ie exposition developed the Electric Light Plant to make a special feature of electric lighting in the evening. Several companies used this opportunity to make exhibits of their apparatus and for their equipment to be used for illumination. The Edison Lamps were used for displays in showcases and pavilions of exhibitors of the Park Building.
The collection contains photographs of the halls of the exposition and a poster which is a souvenir of the electrical display of the exposition. An official Guide of the Centennial Exposition of the Ohio Valley and Central States is included within the collection. (Series 4, Box 99), (Series 3, Box 42, Folder 4).
THE SUMMER CARNIVAL AND ELECTRICAL EXHIBITION, ST. JOHN, NEW BRUNSWICK, 1889
The Summer Carnival and Electric Exhibition held at St. John, New Brunswick, Canada was to celebrate the opening of the Canadian Pacific Short Line to St. John and Portland. The Electrical Exhibition was the most popular of the displays present, containing the Monster Edison Lanm, the Mysterious Electric Fountain, and many other inventions.
The William J. Hammer Collection contains a poster that illustrates some of the leading exhibits at the Electrical Exhibition (Series 4, Box 99).
PARIS UNIVERSAL EXPOSITION OF 1889
The Universal Exposition of 1889 held in Paris was larger than all previous expositions held there. The famous Eiffel Tower was its principal attraction.
A large portion of the exhibit hall within the Palace of Mechanical Industries contained Thomas Edison's electrical inventions, including various electric lamps for use in houses. Variations of the telephone also were shown. During the Paris Exposition Europeans were exposed to the phonograph for the first time. Hammer represented Edison's interests at the Paris Exhibition.
The collection contains articles from New York World, New York Herald and Electrical World on Edison's exhibits at the Paris Exposition (Series 3, Box 44, folder 6). A scrapbook of photographs from the exhibition showing exhibit buildings and halls and loose photographs showing Edison's exhibits are included in the collection (Series 4, Box 98).
THE CRYSTAL PALACE EXHIBITION OF 1892
The Crystal Palace Exhibition of 1892 was held in London. Hammer displayed a great variety of products in the machine room of the Electrical Exhibition. Sockets for controlling individual incandescent lamps on alternating currents and the Ward Arc Lamp for use on incandescent circuits were just a few of the items displayed. Edison's companies displayed specimens of all types of incandescent electric lamps for public and private illumination. They also displayed primary batteries for use in telegraphy, telephony, household work, and engines.
The William, J. Hammer Collection contains a variety of photographs of the electrical exhibition. The Official Catalogue and Guide of the Electrical Exhibition is also contained within the collection (Series 4, Box 99), (Series 3, Folder 2, Box 42).
LOUISIANA PURCHASE EXPOSITION, 1904
The Louisiana Purchase Expostition of 1904, held in St. Louis, Missouri from April 30 to December 1, celebrated the centennial of the Louisiana Purchase. The nineteen million people who attended made it the largest exposition ever. The year 1904 marked the twenty-fifth anniversary of Edison's invention of the carbon filament lamp and central power station system.
F.J.V. Skiff, the exhibits classifier for the fair, developed a twofold classificatory arrangement. He organized exhibits in a sequential synopsis corresponding to the sixteen different departments of the exposition. The principal exhibition buildings were built in the shape of a fan. The departments of education, art, liberal arts, and applied sciences-including electricity - headed the classification, Skiff noted, because they "equip man for the battle and prepare him for the enjoyments of life.' Departments devoted to displays of raw materials such as agriculture, horticulture, !inning, forestry, fish and game came next. Anthropology, social economy, and physical culture concluded the classification.
The Hammer collection contains photographs of Hammer with other Chairmen of Domestic and Foreign Jurors of the Electricity Section of the International Jury of Awards of the Louisiana Exposition and Hammer as chairman of the jury on telegraphy, telephony, and wireless. (Series 4, Box 102). A pamphlet by the American Telephone and Telegraph Company on the exhibit of the Radiophone at the Department of Applied Science is also part of the collection (Series 3, Box 42, Folder 5).
THE PANAMA-PACIFIC EXPOSITION OF 1915
The Panama Pacific Exposition celebrated the opening of the Panama Canal and the four hundredth anniversary of the European discovery of the Pacific Ocean. It was held in San Francisco from February 20 to December 4, 1915. Approximately nineteen million people attended the exposition.
The eleven main buildings of the exposition were grouped around a central court of the Sun and Stars at the entrance of which was the famous Tower of Jewels. The main group of exhibits comprised the Palaces of Education, Liberal Arts, Manufactures, Varied Industries, Mines,
Transportation, Agriculture, Horticulture and all kinds of food products. During the exposition special days were set aside to honor industrialists Henry Ford and Thomas Edison. The Pacific Gas and Electric Company provided a large searchlight to flash out a Morse code greeting on the nighttime sky for their arrival.
The William J. Hammer Collection contains a pamphlet on the "Illumination of the Panama-Pacific International Exposition." The pamphlet describes the lighting of the exposition, and the use of arc lamps ' searchlights, incandescent electric lamps, and gas lamps (Series 4, Box 99), (Series 3, Box 43).

Biographical / Historical:
Victor Leaton Ochoa (1850-1945?) was born in Ojinaga, Mexico. Ochoa later moved to Presidio del Norte, Texas, (Presidio is on the Rio Grande River) and became a United States citizen in 1889. Ochoa was the son of Juan Ochoa, a customs collector in Presidio.
Victor Ochoa was a journalist/writer, founding (El Hispano-American andEl Correo del Bravo) ; a politician (running unsuccessfully in El Paso); a union leader founding (La Union Occidental Mexicana to help Mexicans in the United States preserve their language); a revolutionary (opposing the Mexican government of President Porfirio Díaz, the President of Mexico from 1876 to 1880 and from 1884 to 1911); a prisoner, corporate president of the International Airship Company and the Ochoa Tool and Machine Company; miner and inventor. Ochoa was bitterly opposed to the dictatorship of President Porfirio Díaz. He became involved in the fight by Mexican rebels in the early 1890s to overthrow Diaz. Some consider Ochoa to be the originator of the revolt, and Díaz ultimately issued a $50,000 reward for Ochoa, "dead or alive." Ochoa's participation in Mexican revolutionary activities led to his arrest in 1894 for supplying and hiring Mexican dissidents in El Paso, Texas, thus violating United States neutrality laws. As a result of his illegal actions, a federal warrant was issued for Ochoa's arrest. The Texas Rangers as well as the U.S. Marshal Service sought Ochoa. In October of 1894, Pecos County Sheriff A. J. Royal and Texas Ranger James W. Fulgham arrested Victor Ochoa while rounding up suspected horse thieves. Ochoa was put in the Pecos County Jail and promptly escaped. He was eventually found and returned to El Paso. Ochoa was ultimately sentenced to two years in federal prison at Kings County Penitentiary in Brooklyn. Ochoa was stripped of his United States citizenship, but it was ultimately restored by Theodore Roosevelt in 1906.
Ochoa was as committed to inventing as he was to his revolutionary ideals. He was known to reside in the New York City and the Patterson, New Jersey area in the late 1890s. Ochoa's issued patents list him at New York, New Jersey, and Texas addresses. He also worked with Watson E. Coleman, a solicitor of patents in Washington, D.C. Coleman helped Ochoa file for and obtain patents in other countries such as Czechoslovakia, France, Germany, Great Britain, Japan, Mexico, Netherlands, Poland, and Spain. Ochoa's patents include: a magnetic brake (US Patent No. 867,147); a reversible motor (US Patent No. 718,508); a rail magnetic brake (US Patent No. 873,587); a windmill (US Patent No. 1,319,174); and a wrench (US Patent No. 1,417,196 and 1,454,333).
Ochoa had a strong interest in aviation. He created the "Ochoaplane," circa 1908-1911. He designed it with an automobile in mind, and it included collapsible wings so that it could be housed in a garage or barn. He also incorporated the International Airship Company in Patterson, New Jersey, presumably to manufacture his "airships." Ochoa was imprisoned at the United States Penitentiary in Leavenworth, Kansas on February 18, 1917 and was released on May 1, 1918 upon completion of his sentence. In a September 17, 1917, letter written from Leavenworth, Ochoa asks the Naval Consulting Board to consider the use of metal wings constructed in such a manner that they fold back and over the body of the airship. Ochoa called this his fluttering wing machine. Ochoa's letter is deliberate, and he writes, "There was no desire on my part of abandoning this and three other patents that at this time went to issue. At that time I was taken sick with consumption and my struggle for life then became my sole purpose and then there arose other circumstances, over which I had no control, to prevent my taking them out."
Ochoa married Amanda Cole, granddaughter of Thomas Cole, the American painter, whose most famous painting isThe Last of the Mohicans . They had one son, Stephen Ochoa. Victor Ochoa returned to Sinaloa, Mexico, in 1936, and it is believed he died there in 1945.
