was allegedly Chambers' boss in the Communist
underground, succeeding J. Peters. Chambers
said Bykov instructed him to begin collecting
documents to be passed on to the Soviet Union.
accounts of his relationship with Bykov were
amplified over years of retelling. Bykov was
not mentioned by Chambers in his 1939 interview
with Adolf Berle, according to Berle's notes
from the session. In
his interview with the FBI in 1942, he said
he had only met Bykov in passing. He told a
similar story to the FBI in a 1945 interview.
FBI was never able to establish that Bykov had
ever entered the U.S. or that he existed. Julian
Wadleigh testified he had met Chambers'
boss, who he identified as "Sasha,"
but that the man had only one arm. Chambers
said Bykov had two.
