Allan Robert Rosenberg was an accused Soviet spy.
Witt had succeeded Harold Ware as leader of the underground Ware group of Soviet spies upon Ware's death in 1935. Witt placed Rosenberg in charge of a group of six to eight attorneys during a Congressional investigation into the questionable activities of the NLRB in 1938 and 1939. Rosenberg had been a member of the National Lawyers Guild up to 1940 and was investigated by the Dies Committee.
Rosenberg was a member of the Perlo group of Soviet spies during World War II. In November 1943, Earl Browder turned control of the group over to Jacob Golos two months before his death and it subsequently was taken over by Elizabeth Bentley. While employed as the Chief of the Economic Institution Staff for the Foreign Economic Administration, Rosenberg allegedly supplied the Soviet Union with voluminous observations, recommendations, plans and proposals made by various government officials concerning the handling of postwar Germany. He also worked on the Board of Economic Warfare since 1941. Rosenberg's name appears in clear text in a December 1944 Venona decrypt as the source of a State Department memo.
