Tweedy was born to an American family in London, where his father was working as a banker. He was educated in England, and spent six months in Freiburg, Germany in 1933.
After graduating from Princeton University in 1937, with a degree in European history, he joined the advertising firm Benton and Bowles in New York City. In 1942, he volunteered for naval intelligence and served in North Africa and Europe interrogating German U-boat crews.
After the war, he briefly returned to advertising before being recruited by the CIA. He was dispatched to Bern, Switzerland, in the late 1940s, returning to Washington in 1950. He served as chief of station in Vienna from 1953 to 1956, in London from 1956 to 1959 and again in the late 1960s.
In 1975, George Kalaris asked Tweedy to investigate the CIA's handling of Anatoly Golitsin as well as charges by Clare Petty that counterintelligence chief James Angleton was himself a Soviet mole.
After his retirement, he worked with Recording for the Blind and Dyslexic, becoming national chairman.
