Karl Warner Jessop Sr. (lovingly known as "Kiddle") was born June 11, 1932 to Joseph Lyman Jessop Sr. & Rachel Maleta Porter in Salt Lake City, Utah. He was their fourth child and the eldest son of his mother. He spent his childhood living on Highland Drive (Salt Lake) and his teen years in Antimony, Utah with many of his 37 siblings. As an adult, he returned often to Antimony to camp and fish with his family. He lived most of his life in Lehi, Utah and served in the Korean War.

Karl was a God fearing man who tried to emulate Christ in all that he did. He lived all the principles of the gospel of Jesus Christ as revealed to the Prophet Joseph Smith. He was known as hardworking, dedicated, faithful, steadfast, and resilient. Karl was a quiet man with a humble and stalwart devotion to the gospel and a selfless service to his fellow man. He was at every work project and served wherever and whenever help was needed, consecrating his efforts to the Lord and expecting nothing in return. He was a Jack-of-all-trades and worked in construction and remodeling until past the age of 90, and also served as the Water Master of west Lehi to Elberta for many years. When not working or serving others, he loved playing pinochle, chess, and horseshoes, fishing in Antimony, reading, and most of all – his family. He lived by the motto: When ye are in the service of your fellow beings, ye are only in the service of your God. (Mosiah 2:17)

He died January 26, 2023 in Saratoga Springs, Utah at the age of 90, after a short but valiant battle with cancer, surrounded by many of his family. He is preceded in death by his parents, most of his siblings, several of his sons/daughters-in-law , three of his children who died in infancy, and many other cherished family and friends.
