![]() The building initially housed the Army Signal Corps museum and is now used as the Education Center here, where more than 4,000 training courses are offered annually. His work with radio changed the world.įittingly, the celebration took place in Armstrong Hall, Building 551, which was named after Armstrong on May 24, 1955. Much of Armstrong's work centered on the development of frequency modulation (FM) radio technology. Edwin Howard Armstrong's 119th birthday.Īrmstrong, who held dozens of patents, allowed the free use of those patents by the Army during World War II. 16, a couple days early, to celebrate the anniversary of what would have been Maj. Edwin Howard ArmstrongįORT MONMOUTH, N.J. "The continuous good fortune which has followed me, providing second chances at inventions when the first chance was missed and tossed away, has been all that a man could hope for and more than he has any right to expect." - Maj. ![]() Tyrone Johnson cut the Signal Corps insignia birthday cake at the celebration of what would have been the 119th birth of Maj. Strong, commander CECOM Life Cycle Management Command, and Command Sgt. On the contrary, the successive developments in radio transmission proved all of his merits, so much so that today we still enjoy some of his precious intuitions.Maj. Marion, the widow, took up the case again against RCA and, after a long process, finally obtained justice.Īrmstrong's career, marked and almost jinxed by the trials of the patent disputes, came to a tragic conclusion. Army in the Second World War, making improvements to the long distance FM system and to continuous wave radar, patented in 1953 the Multiplexing FM, a system of multiple transmissions on the same wavelength.įorced to negotiate with the RCA because he was no longer able to sustain the legal fees, Armstrong fell into a deep depression and, on January 31st 1954, committed suicide, jumping to his death from the thirteenth floor of his New York apartment. Rights, however, that the RCA did not want to recognize, resulting in another legal battle.Īrmstrong, who had also collaborated with the U.S. In 1945, the frequency allocations established by the FCC (Federal Communications Commission), under the influence of David Sarnoff's RCA (Radio Corporation of America), penalized the FM system and Armstrong, who could have obtained significant rights from his patent. But the FM system encountered much resistance, on the one hand because it challenged an industrial organization founded on the AM system and, on the other hand, because it presented itself as an eligible candidate in the competitive tender for the wave band allocation, in which the newly born television was also participating. In 1937 he financed the construction of the first FM radio station in Alpine (New Jersey). In the meantime, he was perfecting a system of frequency-modulated (FM) transmission, in place of amplitude-modulated (AM) transmission, a system which he patented in 1933, after years of experimentation in the laboratories of Columbia University. ![]() Even in this case, after varying sentences, Armstrong was not able to obtain full recognition for his original contribution. Upon his return home, he faced a wearing legal battle (1922-1934) with De Forest for the rights over the feedback or regenerative circuit. There he patented the superheterodyne circuit, that he had been developing for quite some time, but was obliged to face a lawsuit, which he lost to Lucien Lévy. Born in New York in 1890, Edwin Armstrong graduated in engineering from Columbia University, and later served in France during the First World War, enlisted in the U.S.
