Ignacy Witczak

Ignacy Witczak was a GRU illegal officer in the United States during World War II.

He operated under a cover of a student and then instructor at the University of Southern California in Los Angeles in the 1940s.

[1] Shortly after the defection on 5 September 1945 of Igor Gouzenko, a GRU code clerk at the Soviet embassy in Ottawa, Samuel Witczak, an instructor at the University of Southern California, disappeared from a beach in Southern California, never to be seen again.

[3] Recent document releases in Britain and Russia, one showing Kim Philby reported on him, identify Witczak as “Litvin” and explain what happened to him after returning to the Soviet Union.

Litvin's GRU career ended during a purge of Jews, but he survived that, later becoming a translator of American books on intelligence.
