'''David Greenglass''' (1922- ) was  recruited into Soviet espionage by his sister [[Ethel Rosenberg]], who with her husband [[Julius Rosenberg]] were executed for committing conspiracy to commit [[espionage]] in 1953 for providing American nuclear secrets to the [[Soviet Union]]. Greenglass shared an interest in Communism with the Rosenbergs. He married Ruth in 1942, and they joined the [[Young Communist League]] shortly before Greenglass entered the U.S. Army in 1943. A talented machinist at the Army base in Jackson, Mississippi, Greenglass was promoted to sergeant assigned to the secret [[Manhattan Project]], the wartime project to develop the first [[nuclear weapon]]s. He was first stationed at the massive uranium enrichment facility at Oak Ridge, Tennessee, and later worked at the secret [[Los Alamos National Laboratory|Los Alamos]] laboratory in [[New Mexico]]. He later told how he slept through the first test of the atom bomb and made artificial diamonds at the laboratory.

In 1950, UK and US intelligence agencies had discovered that a Los Alamos theoretical physicist, [[Klaus Fuchs]], had also been a spy for the USSR during the war. Through Fuchs' confession, they found that one of his American contacts had been a man from Brooklyn named [[Harry Gold]], who had then passed Fuchs' information on to a Soviet agent, [[Anatoli Yakovlev]], who then would pass it on to his controllers in the USSR. Through Gold, the FBI's trail led to Greenglass and the Rosenbergs, who had also used Gold as a courier. When Fuchs was first captured, Julius gave the Greenglasses $4,000 to finance an escape to Mexico. But they went to the Catskills instead and used the money to seek out legal advice.

After his release in 1960, the Greenglasses lived in [[New York City]] under an assumed name. In 1996, Greenglass admitted to New York Times reporter Sam Roberts that he had lied under oath about the extent of his sister Ethel's involvement in the plot, wanting to protect his wife Ruth. At the trial, he testified that Ethel Rosenberg typed his notes to give to the Russians, when it was probably [[Ruth Greenglass]]. Soviet intelligence officers later said they believed Ethel was not an active part of Julius's espionage ring, and Greenglass's crude drawings were not very useful to them since they already possessed Klaus Fuchs' superior information. Greenglass explained, "Look, I had a wife and two children. I didn’t care so much what happened to me, but I cared what happened to them.” When Roberts asked Greenglass if he would have done anything differently, he replied, "Never."
