Summary

Exhibit 8 at the trial of Julius and Ethel Rosenberg, a drawing of an implosion-design nuclear weapon by David Greenglass, created a few days before the trial began in 1951. The drawing was the first time the implosion design was allowed to be made public. Despite being declassified by the Atomic Energy Commission, it was immediately impounded as a threat to national security by the Rosenbergs' lawer, and was only released in 1966 after an investigation into the Rosenberg trial evidence (where it was criticized by experts as very crude and not of any likely intelligence value).
