Harold David Aggeler

Harold David Aggeler, 82, of Raytown, Missouri passed away peacefully in his home on Monday, August 10, 2026. Harold will be remembered for the love and care he showed to his family throughout his life, his longtime devotion to his wife Charleen, the pride he had for his children, grandchildren and great grandchildren, as well as his quick wit, sharp sense of humor, analytical mind, endless creativity, love of learning, and ability to build anything and fix everything. He was a showman who re-invented himself many times over. He was smart, curious, adventurous, and fun to be around, and he led a very full and fascinating life.

Harold was born on November 21, 1943, to Hubert (“Buddy”) and Bernice (Schuster) Aggeler in Boonville, Missouri. He was one of ten children, and he greatly valued having grown up on a farm, learning the meaning of hard work, exploring the outdoors, and figuring out how things work (and how to fix them). He graduated from Otterville High School in 1961, and he then attended technical school to learn about electronics. He met the love of his life, Charleen Provinge, once he moved to the Kansas City area, and they married on October 8, 1966 at Holy Cross Catholic Church in Kansas City. Harold and Charleen were about to celebrate their 60th wedding anniversary.

In 1968, Harold enlisted in the U.S. Army and bravely served in Vietnam. He was trained as a field radio mechanic, and he was honorably discharged from the service in 1969. He was a patriotic American and was very proud of his military service. Harold loved being a veteran and having served his country.

Once he returned from Vietnam and concluded his military service, Harold began a series of professional endeavors that allowed him to use his analytical, creative mind and his entrepreneurial spirit. He started out in electronics working for a small company in Raytown and went on to start his own business making fluorescent shop lights. From there, he started another business installing satellites on commercial buildings. And he ultimately settled on designing and creating redwood shelves for collectibles and selling them at craft shows around the Midwest. Harold and Charleen ran their successful crafting business together for many years. It was called Lindsey Originals, named after their extra special daughter Lindsey, who was born with Down’s Syndrome.

Harold considered his big family to be his greatest accomplishment in life. He loved coming from a big family, and he loved having a big family. He is survived by his beloved wife Charleen, his daughter Kristen and husband Kevin of Lone Jack, his son Gregg and wife Sarah of Oak Grove, his special daughter Lindsey of Independence, and his youngest daughter Jessica and husband Josh of Kingsville. He also leaves behind eight grandchildren - Kaley, Lane, Garret, Ben, Braydon, Will, Burke and Huck, and three great grandchildren - Wrenleigh, Keaton and Becknir (and one more on the way). He is also survived by his sister Juanita (Don), sister Phyllis, brother Lyle (Carolyn), sister Marilyn (David), and brother Ted (Vicki). He was preceded in death by his parents, his brothers Father Vince, Don (Dorothy), and Ted Ray, and his sister Maureen.

Harold will be greatly missed and always remembered for the pride he constantly exhibited for his family, as well as for his many clever sayings, salty jokes and stories, and varied interests he fostered over the years. He built robots that he took to elementary schools and hospitals to inspire and entertain children. He designed and built dune buggies and loved to take them on long drives around the city with his kids and grandkids. In his later years, he devoted himself to taking care of his wife Charleen through impacts from Alzheimer’s, refurbishing and modernizing the robots he built in the 70’s and 80’s, enjoying flowers and birds on his deck, and getting a kick out of his playful Maine Coon cat named Mollie.

A Memorial Mass will be held at Holy Spirit Catholic Church in Lee’s Summit, Missouri on Saturday, August 22, 2026 at 10:30 a.m. All are welcome to join in remembrance of Harold. The church is located at 1800 SW State Rte 150, Lee’s Summit, MO 64082. There will be a private family inurnment at Mount Olivet Cemetery in Raytown, Missouri.
