David Gene Kleckner passed away on July 29, 2025, leaving an indelible mark on many
people's lives.
Dave was born on July 1, 1955 in Carthage, IL to William and Betty Kleckner. His youth
was spent hunting with his dad and sister, taking his brother for reckless bicycle rides,
and working on the farm. Later, as a proud Pretzel, he devoted his time at Freeport High
School to the marching band (trombone), DeMolay International, and FFA. Shortly after
graduating in 1973, Dave enlisted in the Air Force and moved to Southern California,
where he was stationed at Norton AFB in San Bernardino for two years. Dave quickly
took to the laid-back SoCal lifestyle and partook in one of the most popular past-times of
that era and location, cruising E Street in his meticulously kept Plymouth Duster. It was
during one of those drives in early 1976 that he met his future wife of almost 49 years,
Diana.
Dave and Diana married on New Year's Eve of 1976 and moved to Freeport, IL for a
short time, with Dave going to back to farmwork. In 1978, he made the decision to head
to college and was accepted to Cal Poly Pomona in the Agricultural Sciences
department, thus requiring a move back to CA. He graduated from Cal Poly in 1982,
and he and Diana welcomed their first-born, Alexis, that same year. In 1984, Dave and
Diana purchased their forever home in Rialto, CA when he was hired by the Agricultural
Operations department at UC Riverside. They welcomed their second child, Ethan, the
following year. Dave ultimately worked at UCR for 34 years, tending to research crops
on his tractor, bringing home fresh produce year-round, and taking his kids to the
annual Christmas parties where the White Elephant gift exchanges would seemingly
last for hours.
After his retirement in 2018, Dave established a daily routine of morning walks, running
errands, taking care of Diana, and visiting with neighbors. Until the day he passed,
Dave religiously kept in touch with his family in IL and old work colleagues, and
apprised his kids of local goings-on since they had long moved away. He will forever be
remembered for his friendly and outgoing personality, most excellent taste in classic
hard rock, steadfast support of his wife, fondness for classic cars, and affinity for
"Jeopardy," amongst countless other unique qualities that made him the absolute best
husband, father, and brother. Dave's lifelong hobby of collecting model tractors,
subscribing to magazines like Illinois Farmer and Toy Farmer, and frequent trips back to
IL when his children were younger to visit family and friends all reflected his absolute
love for and appreciation of his birth state, even though he was a CA resident most of
his life. Farming was always in his blood.
Dave is survived by his wife, Diana; children, Alexis (Dan) and Ethan (Tess);
grandchildren (six loving kids who will dearly miss their Grandpa/Papa); siblings, Kay
(Brian) Edler, Chris (Rhonda) Kleckner, David (Lynn) Merkwan, Mary Roberts;
aunt, Karen Nudd; cousins, Stephanie Nudd, Jeff (Carrie) Nudd; and numerous nieces
and nephews.
He was preceded in death by his parents, uncle (JC Nudd), and sister-in-law (Pat
Reed).
Dave's memorial service will be held in CA at Fontana Mortuary, 8030 Mango Ave,
Fontana, CA 92336 on Friday, August 15 th from 2-6pm. A get-together to celebrate and
remember him will be held in Illinois on a later date. If interested in attending, please
