Donald Niven Wheeler (1913–2002) was an American social activist, teacher, and Communist Party member, as well as an alleged Soviet spy.
[2] According to Allen Weinstein, "Beginning in 1944, virtually the entire range of OSS analytic and planning documents on Nazi Germany and its postwar prospects flowed continuously from General Donovan's Washington headquarters through Wheeler to Pavel Fitin's offices in Moscow.
"[3] As a member of the OSS Research and Analysis Division, Wheeler had government security clearance to receive secret and confidential "ditto" copies of monthly and semi-monthly reports of political developments throughout the world.
Wheeler is alleged to have provided information on the organization and policies of British intelligence services and furnished memoranda prepared by the Foreign Nationalities Branch of OSS on material relating to the particular racial groups and activities within the United States.
Beginning in 1944, the entire range of OSS planning documents on the postwar occupation of Germany are alleged to have been supplied to KGB head Pavel Fitin through Wheeler.
Some observers considered Wheeler the most active operative within the Perlo group, and his complicity was alleged to have been corroborated by information exhumed from the NKVD archives in the 1990s.
Wheeler was subpoenaed as a hostile witness before federal grand juries in Washington, D.C., and San Francisco; his pregnant wife and four children milk the cows.
