"Donovan, the head of WWII's Office of Strategic Services, was a New York Irishman who won the Medal of Honor in WWI. Between the wars, he became successful on Wall Street and a personal friend of FDR. When President Roosevelt was looking for someone to head an intelligence agency not controlled by either the armed forces or the FBI, he called on Donovan. Donovan was at daggers drawn with FBI Director J. Edgar Hoover and the service intelligence branches, and also recruited too many Ivy Leaguers, but the OSS did pull its weight in wartime intelligence. Donovan also drank too much, chased too many women, lost too many relatives at early ages, and generally did not fit into the postwar world, where the CIA replaced his OSS.
