Harvey O'Connor was born March 29, 1898 in Minneapolis, Minnesota, the son of a railway cook. He attended public school in neighboring St. Paul before relocating with his family to Tacoma, Washington, where he completed high school in 1914. Owing to the death of his father and his mother's need for financial support, O'Connor went to work in various lumber camps as a logger after graduation rather than continuing his education. There he joined the Industrial Workers of the World, a radical industrial union espousing the doctrine of syndicalism — the overthrow of capitalism in favor of rule by industrially-defined workers organizations.
Political career
O'Connor was the editor of the left wing Seattle Daily Call during its short-lived existence in 1917 and 1918. Thereafter, he took a position as the editor and business manager of the Farmer-Labor Call of Centralia, Washington. During the 1919 Seattle General Strike which shut down the city for nearly a week during the month of February, O'Connor played a role producing leaflets and agitating on behalf of the strike. His activities caught the attention of the authorities, which subsequently indicted him for criminal anarchy. O'Connor was never brought to trial, however, owing to the loss of a test case by the state on a similar complaint. In 1921, O'Connor went to work as a department editor at the Seattle Union Record, a daily produced by the Seattle labor movement under the editorship of his friend E.B. "Harry" Ault. He stayed with this paper until 1924. In 1924, O'Connor left the Union Record to move to Cleveland, Ohio to take a position as assistant editor of the Brotherhood of Locomotive Engineers' Journal, the monthly magazine of the BLE. O'Connor next went to New York City in 1927 to head the New York bureau of the Federated Press, a left wing press agency which supplied material to newspapers of the labor movement and left wing political organizations around the country. He remained in this position until 1930. When he joined the newspaper, Whittaker Chambers later realized that "Harvey O'Connor was then effective editor of the Daily Worker."
Later years
In later years, O'Connor was a professional author, writing a number of non-fiction books accentuating the lifestyles of the rich and powerful and the difficult situation of the working class for commercial publishers. Some of his publications include Mellon's Millions,The Astors,The Guggenheims,History of the Oil Workers International, and The Empire of Oil. O'Connor remained politically active throughout his life, serving as chairman of the Emergency Civil Liberties Committee from 1954 to 1963 and as chairman of the National Committee to Abolish the House Un-American Activities Committee in 1964. In 1964, O'Connor published his memoirs, regarded by historians as an important work detailing the history of the radical movement of Washington state during the first decades of the 20th Century.
