Philip George Marshall was born on November 13, 1906 in Milwaukee, Wisconsin. In 1937 he graduated from the Marquette Law School with a specialization in labor mediation and arbitration. From 1937 to 1943 he was employed as law librarian and as a member of the Law School faculty of the University of Wisconsin. During World War II he took a leave from the University to work for the Chicago region of the War Labor Board. After the war he continued his legal career in Milwaukee, working as a labor arbitrator on cases assigned by the Wisconsin Employment Relations Commission, the American Arbitration Association, the Federal Mediation Conciliation Service, and various private concerns.
More politically active than his immigrant family, Marshall joined the Socialist Party in Milwaukee when he was fourteen years old, and he maintained this early political affiliation until the late 1930's. During the mid-1940's he joined a number of former members of the Progressive Party in forming the Democratic Organizing Committee (DOC), which was eventually responsible for reorienting the Wisconsin Democratic Party along liberal lines.
Philip Marshall died in Milwaukee on January 19, 1978. He was survived by his wife Marjorie, a partner in his law practice, and daughter Lynn Coe.
