Biography
David Greenglass was Ethel Rosenberg's younger brother; Army machinist at Los Alamos who passed plutonium-bomb sketches to Soviet courier Harry Gold in 1945. Arrested June 15, 1950; turned state's evidence — admitted in a 2001 interview with Sam Roberts that he perjured himself about Ethel typing notes to keep his wife Ruth out of prison. Sentenced to 15 years April 6, 1951; paroled after about 9.5 years; lived under an assumed name until his death.
National Guardian, October 19, 1953, national page 16: The paper identifies David Greenglass as imprisoned at Lewisburg, Pennsylvania, under a fifteen-year sentence. It reports that McCarthy said October 13 he might question Gold and Greenglass in his new inquiry. The term is imposed punishment, not time already served, and possible questioning is not a new prosecution or arrest.
