individual was not working in the Schevchenko network, but apparently had been working, according to information, under Semen M. Semenov, who, at one time, operated Harry Gold. According to information, the Soviets, in 1944, were having considerable trouble with Malisoff as he wanted a sizable lump sum payment to help him establish a laboratory. When his request was flatly refused by his Soviet contact, Malisoff complained with considerable irritation that his intelligence production had been worth millions of dollars to the USSR and his request for aid was ⟨meager⟩. Malisoff, who is now deceased, was, in 1944, the owner and General Manager of the Unified Laboratories, Inc., Room 621, 1775 Broadway New York City. This concern was principally engaged in research on lubricating processes for war industries and on applications ⟨of⟩ biochemistry. We had investigated Malisoff earlier on the basis that we had observed him in contact with Gaik B. Ovakimian, a known Soviet agent, during 1940 and 1941. As noted previously, we are not engaged in any investigation of Malisoff at the present time on the basis of his death, which occurred on November 16, 1947.
INFILTRATION OF UNITED
STATES GOVERNMENT AGENCIES
Silvermaster Network
The information deals in part with the operations of the MGB in their recruitment and use of personnel in various Government agencies previously known to us in our investigation in the Nathan Gregory Silvermaster case. Individuals positively or tentatively identified from ⟨information⟩ and who were employed in Government agencies, included Nathan Gregory Silvermaster, Ludwig Ullman, Bela and Sonia Gold, Victor Perlo, Harry Magdoff, Peter Rhodes, Allen Rosenberg, Harold Glasser, Duncan Lee, and Harry Dexter White. All of the above individuals were implicated in the Silvermaster network according to information provided to us by Elizabeth T. Bentley. In addition to the above individuals, we have also identified from information other members active in network which include Joseph Katz, Anatoli B. Gromov, and Jacob Galos. Joseph Kats is the subject of a separate write-up in connection with other espionage activities on his part.
