Warren Billings

Warren Knox Billings (July 4, 1893 – September 4, 1972) was a labor leader and political activist, who was convicted with Thomas Mooney of the San Francisco Preparedness Day Bombing of 1916. It is believed that the two were wrongly convicted of a crime they did not commit. Billings served 23 years in prison before being released in 1939 and finally being pardoned in 1961 by governor Edmund G. Brown. Provided by Wikipedia
