Abstract: Papers, 1938-1977, of Horace Wilkie, a Democratic state senator (1956-1962) from Madison, Wisconsin, who became a Wisconsin Supreme Court justice (1962-1974) and chief justice (1974-1976). Early career files include extensive material from his tenure (1945-1950) as chairman of the Madison Housing Authority as well as information on his two unsuccessful congressional campaigns. Legislative files contain material on issues considered during the 1957, 1959, and 1961 legislative sessions, especially the 1961 sales tax compromise. Judicial files, which document his general professional concerns and involvements rather than specific decisions and rulings, contain extensive material on the state court reorganization efforts of the 1970s in which Wilkie was an active participant.
