The recommendations on May 27, 1954 of the Personnel Security Board of the U.S. Atomic Energy Commission investigation into J. Robert Oppenheimer, director of the Manhattan Project at Los Alamos, stated Oppenheimer had been found in the company of “Joseph W. Weinberg and Clarence Hiskey, who were alleged to be members of the Communist Party and to have engaged in espionage on behalf of the Soviet Union.” Oppenheimer’s security clearance was revoked the following month.


In June 1953, Hiskey was subpoenaed to testify before the Senate Subcommittee on Investigations. In a closed door session, Hiskey was interrogated by Sen. Joseph McCarthy:


In testimony before HUAC and Senate Internal Security Subcommittee, Hiskey repeatedly refused to answer questions about his Communist associations and espionage, and in 1950, he was cited for contempt of Congress. Hiskey resigned his position as associate professor of analytical chemistry on the faculty of Brooklyn Polytechnic Institute and joined the International Biotechnical Corporation, later becoming director of analytical research for Endo Laboratories.


In 1948, the House Un-American Activities Committee (HUAC) established that Hiskey was an active member of the CPUSA and had attempted to recruit other scientists to pass secret atomic data to Soviet intelligence. Congressional investigators concluded:


On 28 April 1944, Army counter-intelligence (G-2) observed a meeting between Clarence Hiskey and Soviet Military Intelligence (GRU) officer Arthur Adams. Hiskey was removed from the Manhattan Project by drafting him into the Army, and stationing him in Canada for the duration of the conflict. While en route, Army counter-intelligence officers secretly searched Hiskey’s luggage and found seven pages of classified notes taken from the Chicago Metallurgical Lab. When the officers subsequently performed a follow up search, the notes were no longer with Hiskey.


Hiskey joined the Chicago Metallurgical Laboratory in September 1943. In May 1944, a message sent by New York KGB to Moscow Venona project was intercepted and decrypted. The message contained information reporting that Bernard Schuster, member of the CPUSA secret apparatus, working for Soviet intelligence, had traveled to Chicago on the KGB’s instructions. The message recorded Schuster’s description of those he had come in contact with, including Rose Olsen, and stating Olsen had been meeting with Hiskey on the instructions of the organization. In July, it appears Joseph Katz had been assigned to the Hiskey case.


Clarence Francis Hiskey (1912–1998), born Clarence Szczechowski, was a Soviet espionage agent in the United States.

He became a professor of chemistry at the University of Tennessee, Columbia University and Brooklyn Polytechnic Institute. For a time, Hiskey worked at the Tennessee Valley Authority and the University of Chicago Metallurgical Laboratory, part of the Manhattan Project. He was the father of Nicholas Sand.
