J Laundergan

October 29, 1938 — February 11, 2022

J Clark Laundergan, age 83, died of natural causes on Friday, February 11, 2022, in Duluth, Minnesota. J is survived by his wife, Jean Laundergan, of Duluth Minnesota; his son Jeff (Jeanette) Laundergan and their sons Jacob and Jonah, of Esko, Minnesota; his son Jeremy Laundergan (Rebecca Butler) and their sons John and Michael Butler of Duluth, Minnesota; and his sisters Ann (Robert) Kauppi of Spokane, WA, and Gail Coon of Jackson MI. He is preceded in death by his mother Adele, absentee father James, and brother-in-law Russell Coon.

J graduated from Iowa State University with a PhD in Sociology and spent his 42-year career at the University Minnesota Duluth, retiring as a full professor. J’s addiction research contributed to the development of the Minnesota Model for alcoholism treatment and segued into research and treatment approaches for drug addiction and compulsive gambling. He volunteered his time and expertise at the Center for Alcohol and Drug Treatment and Tri Campus and Community Coalition (T3C) on College Student Alcohol and Drug Use, was a board member of the Duluth Bethel, and served on the Bishop’s Committee at St. Andrew’s by the Lake Episcopal Church.

J enjoyed outdoor activities in Duluth including sailing, skiing, and biking and was a lifelong reader with a thirst for knowledge which inspired others through thought provoking conversations. J donated his treasured sailboat J/Fore to the Duluth Superior Sailing Association and anyone who sails this boat shares in his legacy.
