he completed his PhD under Richard Feynman. After the war Lomanitz was called to testify before the House Un-American Activities Committee. He adamantly asserted his loyalty to the United States and invoked the Fifth Amendment, and declined to name others involved with Communist activities. The Atomic Energy Commission Personnel Security Board (PSB) found in 1954 that Oppenheimer had stated in 1943 that he did not want anybody working on the project who was a member of the Communist Party, since "one always had a question of divided loyalty" and the discipline of the Communist Party was very severe and not compatible with complete loyalty to the project. Oppenheimer, however, did not identify former members of the Communist Party who were working on the project to appropriate authorities. Lomanitz then worked at several jobs, including as a railroad maintenance worker. In 1962 he began working at the New Mexico Institute of Mining and Technology and later became department chairman, before retiring in 1991. He later moved to Pahoa, Hawaii and died of cancer there at the end of 2002. References Findings and Recommendations of the Personnel Security Board in the Matter of Dr. J.
