OSS

The Office of Strategic Services, the WWII predecessor to the CIA (13 June 1942 - 20 September 1945)

''"Donovan had assembled an elite corps which hailed from America’s most powerful institutions and families. Members of the Mellon family held espionage posts in Madrid, London, Geneva, Paris. Paul Mellon worked for the Special Operations Executive in London. His sister, Ailsa (once known as the world’s richest woman), was married to his commanding officer, chief of OSS London David Bruce, son of a U.S. senator and a millionaire in his own right. J.P. Morgan’s sons were both in the OSS. The families Vanderbilt, DuPont, Archbold (Standard oil), Ryan (Equitable Life Insurance), Weil (Macy’s department store), Whitney were all represented in the ranks of Donovan’s secret army."
