Testimony from Rosenberg brother released in US spy case

The brother of Ethel Rosenberg, who was a star witness against his sister and brother-in-law in a sensational Cold War atomic spying case, minimized his dealings with his sister during an earlier appearance before a grand jury and said that they had never discussed her role "at all," according to US court records unsealed today.
The revelation may heighten public suspicion that Ethel Rosenberg was wrongly convicted and executed in an espionage case that captivated the country at the height of the McCarthy-era frenzy about Communist allegiances.
Rosenberg and her husband Julius were put to death in 1953 after being convicted of conspiring to steal secrets about the atomic bomb for the Soviet Union, though they maintained their innocence to the very end.

The grand jury testimony from David Greenglass, whose damning statements at trial helped secure the convictions of his sister and brother-in-law, had been withheld from public view even as other crucial court records have been unsealed in the last decade. A federal judge in New York, responding to requests from a group of historians and archivists, ordered the 46-page transcript unsealed following Greenglass's death last year at age 92.
Historians had greatly anticipated the release of the records - the final crucial piece of evidence to be made public - in hopes of learning more how a brother came to betray his sister with trial testimony that, decades later, he revealed to be false.

Greenglass, who was indicted as a co-conspirator and was himself sentenced to 10 years in prison, said at trial that he had given the Rosenbergs research data that he had obtained while working as an Army machinist at the Los Alamos, New Mexico headquarters of the top-secret Manhattan Project to build the atomic bomb. He said he saw his older sister transcribing the information on a portable typewriter at the Rosenbergs' New York apartment in 1945.
