Harold DeForest Arnold

Died 10 Jul 1933 at age 49 (born 3 Sep 1883).American physicist whose research led to the development of long-distance telephony and radio communication. He worked at Western Electric on thermionic tubes, which amplified radio and telephone signals, leading to transcontinental telephony (July 1914). Even before the transcontinental line was completed, Arnold was directing work on the development of new higher power tubes to extend telephone service by radio to other continents. The first transcontinental demonstration of radio telephone (29 Sep 1915) was transmitted from New York City to Arlington, Virginia, then to San Francisco and Honolulu. Arnold later became the first director of research at Bell Telephone Labs (1925 to his death in 1933).
