Jon P. Wilcox (born September 5, 1936) is an American lawyer and retired judge. He was a justice of the Wisconsin Supreme Court for 15 years, appointed by Governor Tommy G. Thompson in 1992 and leaving office in 2007. Prior to his time on the Supreme Court, he served for 13 years as a Wisconsin Circuit Court Judge, including seven years as Chief Judge of the 6th Judicial Administrative District of Wisconsin Circuit Courts. Earlier, he represented Green Lake and Waushara counties in the Wisconsin State Assembly as a Republican. Early life and education Wilcox was born in Berlin, Wisconsin, and grew up in nearby Wild Rose. He was valedictorian of his graduating class at Wild Rose High School in 1954, then attended Ripon College. After obtaining his bachelor's degree in 1958, he joined the United States Army and was commissioned as an officer in a military police company. In 1961, Wilcox left the Army and entered law school at the University of Wisconsin, ultimately obtaining his law degree in 1965. Wilcox began in private law practice at the La Crosse, Wisconsin, firm of Steele, Smyth, Klos & Flynn. Wilcox would later refer to Jerry Klos as his mentor. After a few years in La Crosse, Wilcox and his wife purchased 2500 acres of farmland near Wautoma and relocated there. In 1968, he formed his own law partnership, Wilcox, Rudolph, Kubasta & Rathjen. Wisconsin State Assembly Also in 1968, Wilcox was approached to run for the Green Lake and Waushara seat in the Wisconsin State Assembly. He recognized politics as a good way to advance his law career, and decided to enter the race. He soundly defeated Republican primary opponents Scott P. Anger and Clifford D. Bvocik, then went on to win the general election without opposition. In the Assembly, Wilcox would serve on the committees for elections, taxation, the judiciary, and insurance and banking, and served on a joint advisory committee on automobile accident liability. He served on the Governor's commissions on reapportionment and highway safety, and served on a special legislative committee on criminal penalties. He ultimately served three terms in the Assembly, having been re-elected in 1970 and 1972. He did not seek re-election in 1974, facing pressure from his law partners to devote more time to the firm. Though he left the legislature, Wilcox remained involved in politics. He served as Chairman of the Waushara County
