Jon Day Griebel, 79, passed away on Oct. 6, 2019, in Tucson, Ariz., after a brief illness. Jon was born on Nov. 23, 1939, at Saint Marys Hospital in Rochester to Jack Edward Griebel (Ruth Schuldt) and Alice Clark Griebel. Jon married Cynthia (Burd) Griebel on Oct. 5, 1963, in Rochester. Jon passed away one day after their 56th wedding anniversary.

Jon was preceded in death by his mother, father and stepmother, his brother, Charles T. (Paula) Griebel of Longview, Wash.; his sister, Barbara J. (Richard) Atherton of Newark, Ohio; his grandson, Mitchell Nathaniel Barrigar of Tucson, Ariz.; and his grandson, Anthony Daniel Hutton of Tucson, Ariz.

Jon is survived by his wife, Cynthia; his sister, M. Jane Porter, Wilmington, N.C.; his brother, Roger B. Griebel, Longview, Wash.; and his children, Patricia Marie Griebel of Tucson, Ariz., Jon David Griebel of Scottsdale, Ariz., Melissa Ann Griebel (Susan) of Vail, Ariz., and Lori Johnson (Gene) of Reardan, Wash. He is also survived by his grandchildren, Danielle Tijerina, Samantha Griebel, Nicholas Griebel, and Mason Barrigar, all of Tucson, Ariz.

Jon lived in South Troy (Zumbro Falls), Minn., from 1939 to 1958, where he worked on his father's and aunt's farms; in Rochester from 1958 to 1963; in Mazeppa from 1963 to 1966; in Longmont, Colo., from 1966 to 1971; in Cary, N.C. from 1971 to 1978; and settled in Tucson, Ariz., in 1978.

Jon graduated from Rochester High School in 1957. He followed this with a successful career as a software developer with IBM Corp. from 1959 to 1989, when he retired and started ProAct Consulting. Jon cared for the business, non-profit, and personal computer needs of all types of people in Tucson until 2011, when he retired for good.

Two things brought Jon immense joy in his later years: his daily trips to the dog park with his many dogs and his antique John Deere tractor collection that he drove in competitive tractor pulls. His favorite competitor was his daughter, Patty, who rarely bested him.

Jon's work ethic was matched only by his internal moral compass. He always sought to do the right thing. He never met a stranger or lacked a story to tell -- the taller the better.

Jon will be inurned at The Grandview Memorial Cemetery in Rochester at a later date.

A memorial service will be held at 4 p.m. Friday, Oct. 18 at Brings Funeral Home, 6910 E. Broadway Blvd. #2803, Tucson, AZ 85710, with Allan L. Nibert officiating. In lieu of flowers, please consider a donation to Power from the Past, c/o Ruth Senkbeil, PO Box 18348, Tucson, AZ 85731.
