Precursor to the CIA.

The Office of Strategic Services was an intelligence agency set up during World War II. Its head William Donovan had been close to the British Security Coordination (BSC), which was instrumental in the Office's creation. Many BSC agents and collaborators became involved with the OSS.

US President Truman ordered the OSS disbanded on 20 September 1945. However, on 26 September, Donovan's Deputy, General John Magruder secured an order from Assistant Secretary of War John McCloy which preserved its operations as the Strategic Services Unit, keeping alive the hopes of those who advocated what would later become the Central Intelligence Agency.
