Biography
William Z. Foster was the national chairman of the Communist Party USA and the lead-named defendant in the 1948 Smith Act indictment of the party's leadership. His case was severed because of a serious heart condition and he was never brought to trial, but he remained under indictment through the 1950s.
Foster's imprisonment and prosecution reach back well before the 1948 indictment. During the IWW free-speech fight at Spokane in 1909 and 1910 he was jailed for forty-seven days. On August 22, 1922 he was arrested at Chicago after federal and Michigan authorities raided the underground Communist Party convention at Bridgman, Michigan, and was the first Communist leader tried under Michigan's Criminal Syndicalism Act; his 1923 trial ended in a hung jury, divided six to six after more than thirty-one hours, and he served no sentence on it.
