Telegram from Senator Joseph R. McCarthy to President Harry S. Truman

2/11/1950

In this telegram to President Harry S. Truman, Senator Joseph McCarthy of Wisconsin repeats his assertion that he has the names of fifty-seven Communists who are working in the State Department, and calls upon the President to provide Congress with a full accounting of Communist infiltration of the Department, including the role of alleged Communist spy Alger Hiss in protecting security risks. In an undated (and apparently unsent) reply, the President states that McCarthy is not fit to serve in the U.S. government, adding that the people of Wisconsin must be very sorry to be represented in the Senate by such a person.

Jell-O Box Exhibit Used in the Espionage Trial of Julius and Ethel Rosenberg and Morton Sobell

3/6/1951 - 3/29/1951

The prosecution presented this JELL-O box as evidence in the trial of Julius and Ethel Rosenberg and Morton Sobell for espionage. They contended it was used to verify identities at secret meetings. The prosecution stated that Julius Rosenberg cut apart the side panel giving his brother-in-law and sister-in-law, David and Ruth Greenglass, one half and Harry Gold the other. Each would present their two sections upon meeting.

According to trial testimony of David and Ruth Greenglass, after dinner at the Rosenbergs' apartment in January 1945, Julius went into the kitchen with Ruth and Ethel, took an empty Jell-O box and cut a side panel into two irregular parts. He gave one piece to Ruth, saying that the person contacting her and David in Albuquerque would identify themselves by presenting the other half. In cross-examining David Greenglass, defense attorney Bloch challenged his story by asking the flavor of the real Jell-O box. David did not remember. Roy Cohn is credited with selecting raspberry for the facsimile.

Oppenheimer admits lying during investigation

4/16/1954

The Oppenheimer affair occupied center stage throughout much of the 1950's, polarizing the atomic research community and much of official Washington. Oppenheimer's security clearance was suspended after hearings conducted by a special board appointed by the Atomic Energy Commission. During the Board's investigation, Lewis L. Strauss, the Chairman of the Atomic Energy Commission filed a preliminary report in a letter to President Eisenhower (4-16-54) In it, Strauss revealed that Oppenheimer had admitted that he had lied to government investigators and that he had " many and continuing relations with persons known to him to be Communists while he was engaged on the atomic bomb project and subsequently."
