Waller was recruited into the OSS as a twenty-year-old fresh out of college. Waller had an obsession with Tibet, and his first assignment was with the OSS North Africa division. He then rose to deputy Middle East theater chief for couterespionage. Due to his obsession with Tibet, he was constantly trying to bring attention to it as an intelligence target. In his own words:
“I was attracted to that part of Central Asia,” he later commented, “precisely because few others paid much attention to it.”
Joining the CIA after the war, Waller continued his private infatuation with Tibet, using his time in Washington to absorb whatever material he could find on the subject at the Library of Congress. He became the CIA Inspector General, and was also the chairman of The OSS Society whose predecessor was the Veterans of the OSS.
