A brief member of the I.W.W., Thomas Mooney was an American member of the Socialist Party. He was tried and convicted for his alleged bombing at a Prepardness Day Parade in San Francisco on July 22, 1916. Six people died at the event. Many believed he was wrongfully convicted and he soon became a martyr for the Socialist movement. He served many years in San Quentin prison before being pardoned in 1939. He died in 1942.
