Headed by Victor Perlo, the Perlo group is the name given to a group of Americans who provided information which was given to Soviet intelligence agencies; it was active during the World War II period, until the entire group was exposed to the FBI by the defection of Elizabeth Bentley.
It had sources on the War Production Board, the Senate La Follette Subcommittee on Civil Liberties; and in the United States Department of Treasury.
On July 31, 1948, Elizabeth Bentley testified before the House Un-American Activities Committee (HUAC):
MISS BENTLEY: Miss Bentley. I had one other group that I handled, and I had every reason to believe there were other groups also.
MR. STRIPLING: What was the other group that you handled?
MISS BENTLEY: We called it the Perlo group. It was actually an ex-Communist Party unit that I believe had been set up in Washington in the early thirties, and I gather, from what the members of the group told me, that they had been in a minor way collecting information for some years but not in an organized fashion.
Much useful additional information on the activities of the Perlo group was given by the Venona project. The first Venona transcript referencing the Perlo group gives the names of all the members in clear text, as code names had not yet been assigned.
Bentley advised that Jacob Golos informed her he had made contact with a group in Washington, D.C. through Earl Browder. After the death of Golos in 1943, two meetings were arranged with this group in 1944. The first meeting was arranged by Browder and was held in early 1944. The meetings were held in the apartment of John Abt in New York City and Bentley was introduced to four individuals identified as Victor Perlo, Charles Kramer, Harry Magdoff and Edward Fitzgerald.
