NEW YORK – In 1953, at the height of the Cold War, Julius and Ethel Rosenberg died in the electric chair after being convicted of conspiring to pass secrets about the atomic bomb to the Soviets. The government's star witness at their trial: Ethel's own brother, David Greenglass.
On Tuesday, family members disclosed that Greenglass died in July in New York City at age 92.
He had served 10 years in prison for espionage followed by years of living in Queens under an assumed name.
Greenberg eventually admitted that he had lied on the stand against his sister.
The Rosenbergs' sons, Michael and Robert Meeropol, took on the surname of their adoptive parents after the deaths of Ethel and Julius Rosenberg.
The couple insisted to the very end that they were innocent.
