Survived by the love of his life, Patricia (nee O'Neill), who was his wife of 52 years, and proud father of Eric of Waukesha, WI; Kristin (Eric) Dufek of Fox Point, WI; and Gretchen (Carlos Dorta) of Medford, MA. The purest joys in his life were his six grandchildren: Megan and Julia Dufek, Emma and Anna Ruethling, and Clara and Lucas Dorta Ruethling. Further survived by siblings Helen Vernier, Evelyn Ruethling and Mary Hook. Preceded in death his parents, brother Edward and daughter-in-law, Krisy Ruethling.

A graduate of the University of Notre Dame and the University of Chicago School of Business. Upon graduation from Notre Dame, Jim became a Captain in the United States Marine Corps and served three tours in combat during the Vietnam War. After years in banking in Chicago and then Wisconsin, Jim spent the final 23 years of his career as the Administrator of the Beloit Clinic in Beloit, Wisconsin.

He was a man of great honor, conviction, intellect, humor, and compassion who put his family above all else. He was an independent thinker with a curiosity for the world. He loved golf, reading, history, Lake Michigan sunrises and moonrises, good coffee, Door County, Notre Dame football, old fashioneds, steaks on the grill, the Blues Brothers, and Willie Nelson songs. As a loving and doting father and grandfather, he always offered an ear to listen, a shoulder to cry on, sage advice on all matters practical or personal, and a plentiful supply of ice cream. He never stopped dancing with Patricia and expressing his great love for her every day.
