One of the “street names” used by Iskhak Akhmerov, NKGBillegalresident in the United States, in his meetings with sources and contacts during his second US posting (1942-1945). Akhmerov is sometimes confused with an unidentified “Bill” who was named by Whittaker Chambers as his contact from 1934 to the summer of 1936, when Chambers’s “Bill” left the USA.
