Brother testified against sister in Rosenberg spy case
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 brother, David Greenglass.
On Tuesday, family members disclosed that Greenglass had died on July 1 in New York City at age 92.
He had served 10 years in prison for espionage followed by years of living in the New York City borough of Queens under an assumed name.
For years, as the debate raged over the explosive espionage case, Greenglass was vilified by the Rosenbergs’ defenders as the man who sent the couple to their deaths — anger that flared again in 2001 when he admitted he had lied on the witness stand against his sister.
“He was self-aggrandizing, narcissistic, unremorseful,” Sam Roberts, a New York Times reporter who wrote the book The Brother, said on Tuesday.
After his release in 1960, Greenglass hoped to be forgotten for his part in the cause celebre that is still furiously debated to this day.
The Rosenbergs’ sons, Michael and Robert Meeropol, were aware of their uncle’s death last summer but did not seek media attention and received no inquiries at the time, according to their spokeswoman, Amber Black.
Ethel and Julius Rosenberg were convicted in 1951 and executed in the electric chair 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.
He said he had seen his older sister transcribing the secret information on a typewriter at the Rosenbergs’ New York apartment in 1945. That testimony proved crucial in convicting Ethel along with her husband.
“Without that testimony, I believe she would not have been convicted, let alone executed,” Roberts said.
In 2001, Greenglass was quoted as saying he had not actually seen Ethel typing and knew of it only from his wife, Ruth. For the prosecution, however, the typewriter “was as good as a smoking gun in Ethel Rosenberg’s hands,” Roberts wrote.
In the book and a CBS interview, Greenglass admitted he lied on the witness stand about his sister to assure leniency for himself and keep his wife out of prison so she could care for their two children.
