Louis Donald Koontz, 93, died Friday, Oct. 25 at The Legacy assisted living facility in Lafayette, where he had resided for a little over five years.
Born April 23, 1926 in Colby, KS to Carl and Bertha Koontz, Don was raised in Colby and spent most of his life in Glen Burnie, MD, Detroit, MI and Littleton and Broomfield, CO. A lifetime educator with a special interest in mathematics and computer science, Don was also an avid coin and stamp collector, rock hound and dedicated family man.
A Navy veteran of World War II, Don was trained as an electronics technician and served aboard the U.S.S. Tappahannock when it was stationed at Yokohama Bay shortly after VJ Day. While on liberty in Tsingtao, China, he became interested in coin collecting, an interest that led to his lifelong enthusiasm for numismatic pursuits. In the Denver area, he helped found local coin clubs like DAWN (Denver Area World Numismatists) and American Numismatic Error Collectors (ANECS) and played an active role in the Denver Coin Club, Colorado Wyoming Numismatic Association and Northside Coin Club.
While in the Navy, Don learned about St. John's College in Annapolis, MD - a school with a revolutionary educational curriculum called the Great Books Program. As soon as he was discharged, he embarked on a campaign to be accepted to St. John's, and started his education there in 1947.
After graduating from St. John's in 1950, he taught at Linthicum Heights Elementary, where he met and fell in love with a fellow teacher, Alma Gertrude Filbert. The two were wed June 14, 1952, and were married for 62 years, until Gertrude's passing in June 2014.
During the time they lived in Littleton, in the 1960s-1980s, Don taught math and science at Cherry Creek West Middle School and at Prairie Middle School, and earned an MA degree in  Mathematics with a special interest in interdisciplinary approaches to education from University of Denver, while assisting in the DU Math Lab. In the early 1970's, Don was the president of the Cherry Creek Teacher's Association. He was also a lifetime member of the National Education Association.
In his retirement, Don continued to be active in many area coin groups and stamp collecting groups and to continue to mentor students with an interest in these areas. His philatelic affiliations over the years were as numerous as his numismatic groups. He was a member of South Suburban Stamp Club and Cherrelyn Stamp Club in Littleton, and helped found North Suburban Stamp Club in Broomfield.
Retirement also saw him running his own coin and stamp business, Smalltown Numismatics, and indulging in the sheer joy of being a grandfather to his three grands, Samantha, Leah and Joel. As his legacy to his beloved hometown Colby, Don donated his extensive collection of mathematic and science books and other educational materials to the Colby School District in line with his goal of mentoring students with an interest in math and science.
Don was preceded in death by his wife, Gertrude, in 2014 and his oldest son, John, of Lafayette, in 2017.
He is survived by his daughter, Charlotte (Dave) Minor, Lafayette; son Carl (Joanne Dutra), Oregon City, OR; and grandchildren Samantha Gross, Philadelphia; Leah Koontz, New York; and Joel Minor, Denver, as well as two great grandchildren and nine nieces and nephews.

Condolences

“That man is a success – who has lived well, laughed often and loved much, who has gained the respect of intelligent men and the love of children, who has filled his niche and accomplished his task. who leaves the world better than he found it, who has never lacked appreciation of earth’s beauty or failed to express it, who looked for the best in others and gave the best he had.” – Unknown Our sincere condolences for the loss of your father.He was a brilliant man,a mathematician,a dapper dresser and a wonderful dad and grandfather. I know you will miss him terribly.
He was a kind, thoughtful, and brilliant man and I always enjoyed spending time with him. He will be very missed by all who had the pleasure of knowing him. I will always remember the special way he had of captivating my attention when I was little by showing me Items from his collections and telling stories. His love for his family was so evident. My thoughts are with you all and we are sending all our love to you.
I wish I had been able to see Uncle Don more through the years. I know I would have learned much from him. As it is, I learned how much he loved his family and it was abundantly clear how much they loved him. I know you will all miss him and there will now be, as my grandson Everett would say, an Uncle Don-sized hole in the universe for you all, but you are all his legacy, and you’re a strong one. Please know I’m thinking about all of you as you grieve and keenly feeling your loss. He was a wonderful human being. Take care of each other in these difficult first days. Love to you all. Cousin Gail
Our deepest sympathies are extended to Uncle Don’s children and grandchildren at this time of loss. He was a kind and faithful man, who put family first and gave his life’s ambition to the raising up and training of young students. His presence is missed. Jeff and Deb Spaulding and family
Your father was so clever and interesting and lived a fascinating life. I enjoyed getting to know him these last years, and playing games with him and Charlotte. Our deepest sympathies to all of your family. The Frobishers
Don will be missed by so many. He is an individual to celebrate; his was a life well lived. Don became a special part of our family when he befriended our Mom, Ruby Scott, at the Legacy Retirement Home. Don enriched Ruby's life with shared stories, games, meals, episodes of Monk and day to day company. My family will always be grateful for Don's steadfast loyal caring for our mother. Wishing Don's family feelings of comfort, moments of peace, and memories of joy during this difficult time. Pam and Kevin Richau Lafayette, Colorado
