Roger Anthony Koster, 96, passed away peacefully on November 5, 2024, at Atrium Village in Hills, Iowa. Roger was born on September 24, 1928, in Breda, Iowa, to William and Matilda (Grabner) Koster. Growing up on the family farm, Roger developed a strong work ethic and a deep love for the land that would guide him throughout his life.
After high school, Roger worked for his dad with plans to be a farmer. But when the Korean War broke out, Roger was drafted into the Army and was stationed with his Division near the demilitarized zone in southern Germany alongside other NATO forces. Roger contracted tuberculosis (TB) near the end of his service and spent over a year recovering in the VA Hospital in Omaha, Nebraska, and eventually at home in Breda. Because of damage to Roger’s lungs due to TB, doctors at the VA Hospital advised him to give up his plans to farm. With funding available through the VA, Roger was able to enroll at Iowa State (becoming a Cyclone fan for life) and graduated with a degree in Agronomy in July 1957 – a natural extension of his lifelong passion for agriculture.
Roger met the love of his life, Darlene Wolterman, and they both waited patiently (and maybe a bit impatiently at times) as Roger completed his military service and recovered from TB before finally marrying on June 15, 1955. Together, they shared 59 years of love and companionship, building a life rooted in faith, family, and kindness toward others.
Throughout his career as a soil conservationist with the Natural Resources Conservation Service (NRCS) and later as coordinator for Iowa State University Extension’s Big Spring Basin Project, Roger devoted his time and effort to the stewardship of our natural resources and worked tirelessly to address issues related to soil preservation, water quality, and wildlife habitat. Roger also served on various boards including the Clayton County Conservation Board and he was a lifelong member of Ducks Unlimited and Pheasants Forever.
Roger’s love of the land was also apparent in the hobbies he enjoyed. He liked hunting turkeys, pheasants, geese and ducks, preferably with one of his faithful dogs by his side, and he especially looked forward to his annual hunting trips to Canada each fall. Roger was always up for a hike in the timber or across prairies, and he enjoyed rounds of golf with family and friends. But most of all, Roger was a lifelong fisherman at heart, especially when he was fishing alongside Darlene, his children, and above all his grandchildren.
Roger and Darlene loved their children, but it was their grandchildren and great-grandchildren who brought them the most joy. They attended endless sporting events and music concerts, and dropped whatever they were doing when a grandchild or great-grandchild visited.
Roger’s faith was the cornerstone of his life. It guided him through both joyful times and challenges and shaped the kindness and compassion he showed to others around him. He was a member of St Joseph’s Catholic Church in Elkader, actively participating in several roles and on several committees throughout the years.
Roger is survived by his children, Stanley of Palo, Suzanne (Pat) Hyde of Coralville, William (Lisa) of Huntington Beach, CA, Nancy (Tom) Healy of Elkader, and Daniel (Kris) of Van Meter; nine grandchildren, Ryan (Emily) Hyde, Amanda (Stuart) Kunkel, Tyler Koster, Andrew (Abbey) Healy, Danielle (Mitch) Hankey, Elizabeth Healy, Bryon Koster, Owen Koster and Benjamin Koster; nine great-grandchildren and one on the way; one sister, Maxine Heinrichs of Glencoe, MN; sister-in-law Lucy Wolterman of Jefferson, IA; and many nieces & nephews.
