Retired Army major general Roger B. Colton, 90, who served in the Signal Corps, died of cardiac arrest Tuesday at Mount Vernon Hospital in Fairfax County.
Gen. Colton served during World War II as director of the Signal Corps communications officer for the Air research, development, procurement, storage, and issue. He later was air Corps Technical Service Command.
He received the Legion of Merit and the Distinguished Service Medal.
Gen. Colton's work contributed to the development of both radar and an electronic fire-control system for aircraft.
He retired from the Army in 1946. He served as president of the International Telephone and Telegraph Laboratories and as deputy technical director for IT&T during the 1950s.
Gen. Colton was a native of North Carolina. He moved here in 1953. He earned a bachelor's degree from Yale University and a master's degree from the Massachusetts Institute of Technology.
He enlisted in the Army in 1912 and served in the coastal artillery until transferring to the Signal Corps in 1930. He was a graduate of the Command and General Staff School and the Army War College.
He is survived by his wife Ora C., of the home in Alexandria; a daughter Shirley C. Lotz, of Alexandria, three grandchildren and five great-grandchildren.
The family suggests that expressions of sympathy may be in the form of contributions to the Taft School in Watertown, Conn., or the Columbia Lighthouse for the Blind in Washington.
