Judge John I. Williamson was born March 16, 1857, in Carroll County, Missouri. He completed high school coursework at Carrollton, Missouri, then attended Kentucky University/University of Kentucky at Lexington for advanced education. After attending college, Williamson practiced law in Carlisle, Kentucky. Williamson was admitted to the bar September 30, 1891, in Chillicothe, Missouri. He was admitted to practice before the Supreme Court of Missouri on March 25, 1893. In 1903, he returned to Missouri permanently and resided in Kansas City. 

Williamson was a member of the American Bar Association and the Missouri Bar Association. He was also a member of the Kansas City Bar Association, serving as president in 1912. In 1914, he was appointed by then-Governor Elliot Woolfolk Major to a commission of attorneys and judges charged with revising Missouri’s criminal and civil codes of court procedure. For 10 years, Williamson was a lecturer and teacher at the Kansas City School of Law. Additionally, he practiced law in Kansas City for more than 15 years, before he was appointed to the state supreme court. 

Judge Williamson was appointed November 1, 1919, to the Supreme Court of Missouri to fill a vacancy created when Judge Charles B. Faris became a federal judge with the United States District Court for the Eastern District of Missouri. Williamson was sworn in November 3, 1919, as a judge of the Court, where he served until the completion of his term in December 1920.

Williamson then returned to Kansas City and continued to practice law. In 1921, he was a member of the Missouri Bar’s commission on constitutional revision. The following year, he served as chairman of the Missouri Bar Association’s Committee on Illegal Practice of Law by Laymen. He later returned to the Supreme Court of Missouri to argue the case of State ex rel. Lashly v. Becker, which involved state senatorial districts and gerrymandering. 

Judge Williamson died November 19, 1933, in Kansas City, Missouri. He was 76 years old.
