He came to Princeton from La Crosse Central (Wis.) High School, where he was active in football, track, baseball, debating, and the school newspaper.

At Princeton he was editorial chairman of The Daily Princetonian, a member of Whig-Clio, and played rugby. He was a member of Tiger Inn and was in the Woodrow Wilson School. He roomed with William Greider, Walter Mayo, and Robert Sklar.

Jon graduated from Harvard Law School in 1961, married Trudy Shoemaker, and went into the Army at Fort Jackson, S.C. Upon discharge, they moved to Evanston, and he joined Keck, Mahin & Cate as a litigator and then became managing partner.

He developed a love of sailing, handball, and unique business investments, one of which was Will’s Northwoods Inn, a Wisconsin-themed tavern and home for Badger and Packer fans behind enemy lines.

Jon is survived by Trudy; children Jonathan ’84, William, and Katherine ’90; six grandchildren; and his sister. The class extends its deepest sympathy to them all.
