Alger Hiss was a highly regarded adviser to President Franklin Delano Roosevelt. On Aug. 3, 1948, Whittaker Chambers, a senior editor at Time magazine, told the House Un-American Activities Committee that Hiss had given him State Department secrets as a Communist underground member in Washington a decade earlier.
Chambers claimed that he, in turn, passed the documents to the Soviet Union. Hiss denied everything, saying Chambers was just a casual acquaintance.
Chambers took investigators to his Maryland farm and produced a hollow pumpkin. Inside, they found microfilmed State Department documents - documents Chambers said he received from Hiss.
He also handed over typewritten copies of government documents. In the course of the trial, prosecutors produced an old typewriter once owned by Hiss and his wife; they said the typewriter was used to copy the documents, and alleged Priscilla Hiss had done the typing.
There was no trial for spying because the statute of limitations had expired on espionage. Hiss' first jury deadlocked on perjury charges. At a second trial in 1950, Hiss was found guilty of lying to the grand jury when he denied giving Chambers the documents and said he had not seen Chambers after the first of 1937.
Hiss was convicted of two counts of perjury, disbarred and thrown in jail for three years and eight months.
Richard Nixon, a freshman congressman at the time, rose to fame on the coattails of the scandal.
Alger Hiss died in New York City on November 15, 1996. He was 92.
