1855-1926. US labour leader and socialist, who organized the Social Democratic Party 1897. He was the founder and first president of the American Railway Union in 1893, and was imprisoned for six months in 1894 for defying a federal injunction to end the Pullman strike in Chicago. He was socialist candidate for the presidency in every election from 1900 to 1920, except that of 1916. Debs was born in Terre Haute, Indiana. He opposed US intervention in World War I and was imprisoned 1918-21 for allegedly advocating resistance to conscription, but was pardoned by President Harding 1921. In 1920 he polled nearly one million votes, the highest socialist vote ever in US presidential elections, despite having to conduct the campaign from a federal penitentiary in Atlanta, Georgia. His powerful oratory and his evocation of homespun American ideals were the source of his appeal rather than any doctinaire adherence to socialist theory.
