#AceHistory2ResearchNews – October 15 – David Greenglass, who served 10 years in prison for his role in the most explosive atomic spying case of the Cold War and gave testimony that sent his brother-in-law and sister, Julius and Ethel Rosenberg, to the electric chair in 1953, has died at 92.
Greenglass — who admitted decades later that he lied on the stand about his own sister — died in New York City on July 1, according to the Rosenbergs’ sons, Michael and Robert Meeropol.
After his release from prison in 1960, Greenglass lived under an assumed name in Queens, hoping to be forgotten for his part in a McCarthy-era cause celebre that is still furiously debated to this day.
A spokeswoman for the Meeropols, Amber Black, said the brothers were aware of their uncle’s death last summer but did not seek media attention and received no inquiries at the time.
The Rosenbergs were convicted in 1951 of conspiring to steal secrets about the atomic bomb for the Soviet Union and were executed at New York’s Sing Sing prison, insisting to the very end that they were innocent.
Greenglass, indicted as a co-conspirator, testified for the government that he had given the Rosenbergs research data obtained through his wartime job as an Army machinist at Los Alamos, New Mexico, headquarters of the top-secret Manhattan Project to build the atomic bomb.
