It is with profound sadness of his loss tempered by immense happiness for his well lived life that we announce the passing of Karl-Heinz Gustav Mueller, aged 94, born in Bremen, Germany on December 29, 1931, and passed away peacefully with family by his side at Regina, Saskatchewan on March 16, 2026.
Predeceased by his parents, 3 sisters, and his wife Ruth of 63 years, Karl is survived by one sister Erika, his loving children, grandchildren and great-grandchildren; Ron Mueller (Michelle) Colt, Alice; Heather Mueller (Ed Sewell), Kurtis, Tyler (Trudy), Chelsey; Bill (Linda) Mueller, Shea, Braden (Samantha), Morgan, Erika (Patrice) Remi, Raphael, Louis, Yannick; as well as numerous extended family in Germany, Greece and Canada and his adopted Haider, Soloman and Gyurek families.
Karl immigrated in 1952 to Canada with a degree in animal husbandry and worked on farms and raised cattle, until 1967 when the family moved to Regina. He worked at Silverwood then Co-op Dairies until joining Felix Fischer Construction in the mid 70’s where he stayed until retirement. During this time, Karl, along with Felix and a few others formed the North Side Minor Girls Fastball league, the genesis of organized girls and women’s fastball in Regina. He and Felix coached their daughters’ team to multiple Saskatchewan championships, and 2 consecutive heartbreaking losses in the Western Canadian Finals. Karl contributed to a lot of the rule book and umpired softball, fastball, slo-pitch, Rambler Park men’s and others. When not doing that, he watched and cheered. Retirement turned his 10 hour days to 14 hours, helping kids and grandkids with projects, running dogs around and in his final years, playing with and spoiling his beloved great-grandsons all while driving to bring us parts, lunch or coffee until he was nearly 93 years old. Karl lived his final 18 months at Queen Victoria Estates until his passing.
Special thanks to 5F staff at Regina General Hospital, the nurses in the Regina Pasqua Palliative Care Unit and Dr. Greg Baumann for their compassionate care of our Dad.

It hurts to lose a close family member no matter their age. Hopefully you will find some comfort in knowing he lived such a long productive life, leaving you many memories to cherish. I will always remember him on a ball field, as an umpire in many games I pitched and later coached, or as a parent cheering Heather, and her Mistakes teammates on. Thinking of you Heather.

My deepest and heartfelt condolences Heather, Billy and Ron. Had the privilege to know your dad and mom when we were kids. Then as an adult got to share their love of softball for 40 years plus and became very good friends of Karl's. Whenever I think of him it brings a smile across my face and always will. Karl was a special breed they don't make anymore he was very loved by all.
