Esther Marion Armstrong was the widow of Edwin Howard Armstrong, notable for continuing his patent battles after despair drove him to suicide.〔 〕 It took 13 years, but she did win all the patent fights, winning financial settlements that restored her wealth.〔 〕 In her final years she established awards and took other steps to honor her husband's accomplishments. When Marion met Edwin Armstrong she was the secretary of David Sarnoff then an executive at RCA.〔〔 〕 Armstrong was then both an inventor and Professor of Electrical Engineering at Columbia University. He had sold his patents for the autodyne (regenerative circuit) and Superheterodyne receiver to Westinghouse, which then owned RCA, making him a millionaire, and owner of a large block of RCA stock. Marion was described as ''"tall and strikingly handsome"''. Armstrong built Marion what was described as ''"the world's first portable radio"''.〔 〕 He bought her a Hispano-Suiza sports car as a wedding gift, when they wed in 1923. By 1933 Edwin Armstrong had filed key patents for techniques he developed that were to eventually make FM Radio successful. His professional relationship with Marion's former boss, Sarnoff, fractured when Sarnoff who was by then the President of RCA, concluded the development of FM Radio was not in the best interests of RCA, which operated an extensive network of commercial AM Radio stations. RCA, and over a dozen other electronics firms, including Motorola ended up filing competing patents for FM Radio. These protracted patent fights brought Armstrong to the brink of financial ruin.〔 According to ''"They made America"'' Armstrong was oblivious to the toll his struggle was taking on Marion.〔 〕 Marion spent months in a mental hospital after she threw herself into the East River. Finally, on November 1, 1953, Edwin told Marion that he had used up almost all his financial resources. In better times funds for their retirement was put in her name, and he asked her to release a portion of those funds, so he could continue the legal battles. She declined, and suggested he consider accepting a settlement. Enraged, Edwin picked up a fireplace poker, and swung at her. Marion left the apartment, and never saw him again. After just under three months of separation Armstrong wrote Marion an apology and threw himself from his high-rise apartment.〔 Marion inherited her husband's patents, and, by 1967, won all of those patent fights.〔 〕 According to Jim Wesley's book ''Radio Memories'' after she had begun to win the patent fights, she established awards to honor Armstrong's memory as a radio innovator.〔 〕 Marion established the Armstrong Memorial Research Foundation.〔 〕 Marion died on , in New Hampshire, where she had made her home.〔 〕 == References == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Esther Marion Armstrong」の詳細全文を読む スポンサード リンク
