De Forest Radio Telephone And Telegraph Company
DE FOREST RADIO TELEPHONE AND TELEGRAPH COMPANY
MODERN invention rivals ancient miracle in its startling and world-transforming effects. The things which in our youth we were taught to be impossible are now the every day incidents of our life and business. The wireless transmission of intelligence is to most minds the greatest of these marvels, but has with a remarkable rapidity become a practical and indispensable factor in the world's work.
Dr. Lee de Forest, a distinguished electrical engineer and the foremost American contrib-utor to the development of wireless telegraphy and telephony is at the head, as president and secretary of the De Forest Radio Telephone and Telegraph Company, and Charles Gilbert is the treasurer of the company.
The business is that of manufacturers of radio telephone and telegraph apparatus, and the company is the pioneer inventor, developer, and manufacturer of Audion detectors, amplifiers and oscillators, and of the undamped wave system of transmission. The "Oscillion" is the undamped wave transmitter made by the De Forest Company. The plant
of the company is located at 1391 Sedgwick Avenue in Bronx Borough, New York City.
Lee de Forest, the president, was born at Council Bluffs, Iowa, August 26, 1873. He was graduated from Yale (Sheffield Scientific School) with the degree of Ph.B., in the Class of 1896, and received the Ph.D. degree in 1899. He invented the De Forest system of wireless telegraphy and founded the American De Forest Wireless Telegraph Company. The De Forest System has been largely adopted by the United States Government, and has been demonstrated to other Governments including those of Great Britain, Denmark, Germany, Russia, and British Indies, all of which purchased De Forest apparatus previous to the Great War. Many land stations and hundreds of ships have been equipped with wireless apparatus under the De Forest System and subsidiary companies were established in Canada, Great
The present company was organized in 1913, and in its products represents the latest and most progressive development, including the most original advance that has been made in radio improvement. He served in the Army during the Spanish- American War.
His most notable inventions are the Audion, the most sensitive detector of electric waves known; the Audion Amplifier, which as a tele-phone relay made possible the trans-continental telephone service; the Oscillator and the "Os-cillion" transmitter. These inventions have literally revolutionized the entire radio art and the
transmission of written or audible speech.
During the great war the De Forest apparatus became a very prominent factor in the efficiency of the United States Signal Service, and has also been installed by the Gov-ernment in Alaska.
Britain and Brazil.
Dr. De Forest is untiring in his laboratory ex-periments, distinguished as scientist and electrical engineer, and is a Fellow of the American Institute of Electrical Engineers, and of the Institute of Radio Engineers, the New Electrical Society, and the National Geographic Society.
