John J. Kessler

John J. "KC9JLI" Kessler, 79, of Waterloo, IL, died June 2, 2022, in St. Louis, MO. He was born September 3, 1942, in St. Louis, MO.

    He is survived by his wife Judith Ann Kessler nee May; children Tina (Michael) Ford and Cathy Kessler; grandchildren Brenden J. Kessler, Justin A. Kessler, and Brielle F. Kessler; Allison (Dustin) Ervin, and Emmi Lou Ford; brother-in-law Wayne Sweet; sister-in-laws; brothers-in-law; nieces; nephews; and cousins.

    He is preceded in death by his son Thomas R. Kessler; parents Arthur and Constance (nee Koenigsmark) Kessler; sister Virginia Sweet; and aunt Carmelita Koenigsmark.

    John was a member of SS Peter & Paul Church in Waterloo, IL,  a United States Air Force Veteran, longtime member of National Speleological Society, Meramec Valley Grotto (MVG), a certified member of the National Association for Amateur Radio, and a member of Ancient Modulators Amateur Radio Club (KC9JLI). John found happiness with family and all those he encountered in his clubs, neighbors, and community. John was not only intelligent but could fix about anything he put his mind to. John was committed with 42 years as an electrical engineer and committed to his faith. John nurtured his spirituality throughout his lifetime. John found pleasure in caving, ham radio and riding his electric bike. John was very detailed focused but at the same jolly and joyful. John will be most remembered by his warm smile and generosity of himself.

Just remember that he is not really gone but will live on in the hearts and memories of many others. I loved camping with him and MVORs won't be the same without him. I am hoping that Cathy can come to them.

John will be missed. I enjoyed many camping and caving trips with him. We shared a lot of discussion regarding our ham radio hobby. Really really glad to have known him!

John was a key member of the ham community and a very enjoyable fellow.

John was one of my best friends. I’m sorry I didn’t meet him much sooner. He was a brilliant electronics and radio expert. He was always willing to help anyone. A man of many talents and interests. 73 John KC9JLI.

I met John (& Tom) through Scouting. John was so knowledgeable about caving, nature, electronics, & many things; but he was also very kindhearted, friendly, and helpful. John lived out the Scout Law & motto in his everyday life. He was truly a Good guy, and he will be greatly missed.

Omg. I will miss John so much . He and I are the same age and I never knew he had any problems. I always loved talking to him and he was always ready to help me with my radio problems .
