DUANE T. KREUGER, 54, of Creve Coeur Missouri passed away in Northern Minnesota on May 26, 2024. He died doing what he loved most – fishing in Ely Minnesota on White Iron Lake. Duane was an accomplished Geologist and consultant with a keen eye for detail and safety. Duane received his Geology degree at the University of Illinois. He worked at Geotechnology, LLC (UES) for more than 30 years and was well-loved and respected by his peers. He was dedicated to selflessly donating his time and resources to the Association of Environmental & Engineering Geologists (AEG) where he held local and national officer and board positions, including President. Duane was also a prolific contributor to many charitable causes including the AEG Foundation. Duane was known for his quick wit and humor, and his extreme kindness toward others-which we will miss dearly. In addition to fishing, his favorite hobbies were camping, cooking, live music, and teaching others. He was also very creative with a pen in his poems and drawings. He was a loving son of Larry and Jan Kreuger, beloved brother and best friend of Daren Kreuger and sister-in-law Kathie Jenkins Kreuger, and dear uncle to Brad, Adam, and Josh Kreuger, as well as a friend to so many.
