Chiefs of Signal

1880 - 1947    1947 - Present

Major General Joseph O. Mauborgne

1937 - 1941

Joseph O. Mauborgne, 12th Chief Signal Officer, pioneered, with others, the development of the aircraft radiotelephone, the device that would change World War I airplanes from solitary units into a cohesive fighting group. Prior to World War II, Mauborgne supported the development of a revolutionary device known as radar, the communications technology that would most affect the outcome of that war.


After his commissioning as a second lieutenant in the regular Army in 1903, Mauborgne's assignments were interspersed with Infantry tours in the Philippine Islands and stateside installations.


Prior to World War I, he served at the Signal School at Fort Leavenworth and in the office of the Chief Signal Officer. During the 1920s and 1930s, his numerous research and development assignments included being Chief of the Signal Corps Engineering and Research Division and commanding officer of the Signal Corps Laboratory in the Bureau of Standards.


During the early 1930s, Mauborgne was Signal Officer for the 9th Corps area and later Director of the Signal Corps aircraft factory, Wright Field, Ohio. Major General Mauborgne became Chief Signal Officer in October 1937.


As a research-minded chief, Mauborgne supported the development of Army radar and oversaw the mass production of the SCR-268 and SCR-270. He retired on 30 September 1941, only a few months before the SCR-270 was used on the island of Oahu, Hawaii on 7 December 1941, to detect Japanese aircraft some 130 miles away.
