Carl Dreher
Carl Dreher (February 16, 1896 – July 13, 1976) was an electrical engineer, two-time Academy Award nominated sound engineer, and an author who primarily dealt with technical and scientific topics. Directly involved with two technological revolutions—the introduction of radio broadcasting and the development of sound movies—he observed that "No form of communication was safe from the innovative drive of electronics."〔''Sarnoff: An American Success'' by Carl Dreher, 1977, page 101.〕

Dreher was born in Vienna, Austria-Hungary (now Austria) in 1896, and emigrated to the United States in 1899. Beginning in 1908 he operated a small amateur radio station while living in the Bronx,〔"What Business Kills" by Carl Dreher, ''The Literature of Business: Contemporary'', 1946, page 414. (Originally appeared in the June, 1939 ''Harper's Magazine'')〕 and in 1916 qualified for a First Class-First Grade commercial radiotelegraph operator's license. He attended Townsend Harris Hall, the City College of New York (CCNY) preparatory school, graduating in 1913. He then enrolled at CCNY, where his primary instructor was Dr. Alfred N. Goldsmith. The United States entered World War One in April, 1917, and Dreher received his B.S. degree in May, a month early, on the condition that he take a civilian position that aided the war effort. He began employment with the Marconi Wireless Telegraph Company of America, working on war contracts in the company's test shop in Aldene, New Jersey,〔"Memoirs of a Radio Engineer: XVIII" by Carl Dreher, ''Radio Broadcast'', June, 1927, page 109.〕 and also became a member of the Institute of Radio Engineers (IRE).
In 1919 American Marconi's assets were purchased by General Electric and reorganized as the Radio Corporation of America (RCA). From 1921 to 1923 Dreher worked as an operating engineer at RCA's transatlantic radiotelegraph station located at Riverhead, Long Island.〔Dreher (1977), pages 73-74.〕 In May, 1923, RCA established two showcase broadcasting stations, WJZ (now WABC) and WJY, at "Aeolian Hall" in New York City. Dreher was initially the facility's chief control operator, but was soon was promoted to engineer-in-charge.〔Dreher (1977), page 75.〕 Drawing on his experiences, he published articles about radio technology and the emerging broadcasting industry, including, beginning in March, 1925, the monthly "As the Broadcaster Sees It" column in ''Radio Broadcast'' magazine.〔Dreher (1977), page 82.〕
