In 1951, Morton Sobell was tried and convicted with Julius and Ethel Rosenberg on espionage charges. He served more than 18 years in Alcatraz and other federal prisons, traveled to Cuba and Vietnam after his release in 1969 and became an advocate for progressive causes.
Through it all, he maintained his innocence.
But on Thursday, Mr. Sobell, 91, dramatically reversed himself, shedding new light on a case that still fans smoldering political passions. In an interview, he admitted for the first time that he had been a Soviet spy.
And he implicated his fellow defendant Julius Rosenberg, in a conspiracy that delivered to the Soviets classified military and industrial information and what the American government described as the secret to the atomic bomb.
