Edwin E. "Ed" Koopmann, age 84, of Bartelso, passed away Wednesday, July 2, 2025, at SSM Health St. Joseph's Hospital in Lake St. Louis, MO. He was born March 29, 1941, in Bartelso, a son of the late Herman and Cecilia (nee Varel) Koopmann.

In addition to his parents, Ed was preceded in death by his wife, Jane Koopmann (nee Beckemeyer) whom he married July 10, 1970, at St. Anthony's Catholic Church in Beckemeyer and who died October 2, 2012; siblings, Helen (Cornelius) Gebke, Alois Koopmann, and Tom Koopmann; father-in-law and mother-in-law, Vince and Clara (nee VanDorn) Beckemeyer; and sister-in-law and brothers-in-law, Lorene Koopmann, George Vandeloo, and Dave Beckemeyer.

A proud veteran of the United States Army, Ed lived a life of hard work and dedication. He retired from the U.S. Army Corps of Engineers at Carlyle Lake, where he worked in maintenance. In addition to his service, Ed was a lifelong farmer, devoted to his land and his livestock. His commitment to agriculture and community was evident in his membership in the Clinton County Farm Bureau.

Ed was a man of faith and a member of St. Boniface Catholic Church in Germantown. He was also a proud member of the Bartelso Knights of Columbus Council 4745.

Outside of work and service, Ed enjoyed a simple, fulfilling life. He loved golfing, cheering on NFL football games, and, most of all, spending time with his grandchildren. Whether it was attending their school events, watching their sports games, or simply enjoying quiet moments together, Ed found great joy in being a grandpa.
