Peter

A “street name” by which Whittaker Chambers, a self-admitted Soviet espionage agent in 1930s, knew the Russian who was his contact from the latter part of 1936 until early 1938. After Chambers’s defection, another defector from the Soviet cause, Walter Krivitsky, told him that “Peter”’s true identity was “Colonel Boris Bykov.” But when, in 1949 and 1950, several other Americans who had been in contact with “Peter” from 1936 to early 1938 described him to the FBI, their descriptions did not fit Krivitsky’s description of “Colonel Bykov.”
