David Greenglass (March 2, 1922 – July 1, 2014) was an atomic spy for the Soviet Union who worked on the Manhattan Project. He was briefly stationed at the Clinton Engineer Works uranium enrichment facility at Oak Ridge, Tennessee, and then worked at the Los Alamos laboratory in New Mexico from August 1944 until February 1946. He provided testimony that helped convict his sister and brother-in-law Ethel and Julius Rosenberg, who were executed for their spying activity. Greenglass served nine and a half years in prison.
Greenglass was born in 1922 in the Lower East Side of Manhattan in New York City. His parents, Barnet and Tessie, were Jewish immigrants from Russia and Austria, respectively. He attended Haaren High School, and graduated in 1940. He attended Brooklyn Polytechnic Institute but did not graduate.
Greenglass married Ruth Printz in 1942, when she was 18 years old. The two joined the Young Communist League shortly before Greenglass entered the U.S. Army in April 1943. They had a son and a daughter. He worked as a machinist at Fort Ord, California, and then at the Mississippi Ordnance Plant in Jackson, Mississippi. In July 1944, Greenglass was assigned to the secret Manhattan Project, the wartime project to develop the first atomic weapons. He was first stationed at the Clinton Engineer Works uranium enrichment facility at Oak Ridge, Tennessee, but was there for less than two weeks. In August 1944 he was sent to the Los Alamos laboratory in New Mexico. In order to pass his security clearance, he disguised or omitted details of his communist associations, and had friends write glowing references.
