Ignacy Witczak
Ignacy Witczak was a GRU "illegal" officer in the United States during World War II. Witczak's code name with the GRU and as deciphered by the Venona project and other counterintelligence investigations was "R". He operated under a cover of a student and then instructor at the University of Southern California in Los Angeles in the 1940s. 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. Later his wife disappeared as well. In a 1952 Senate report, he was identified as a Soviet spy; his name had surfaced in the Venona decrypts. The FBI search for Witczak is described in the memoirs of FBI special agent Robert Lamphere. The FBI had learned Witczak had entered the United States from Canada on a false passport and suspected Witczak was not his true name. Later the FBI was able to trace some of Witczak's former agents, but never learned what happened to him. "Enemy Amongst Trojans" tells the rest of the story. 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. Evidence of espionage.
