Jack Alden Holst was born January 9, 1939, in Cedar Rapids, Iowa, to Paul and Ruby Holst. He passed peacefully at Westview Healthcare Center in Sheridan, WY, on January 2, 2024, with family by his side.

He was the youngest of four boys raised on a farm in Iowa. He received his BS degree in Geology from Iowa State in 1960. While at Iowa State, he taught field geology for a summer in Wyoming. He graduated as a distinguished military graduate from ROTC and received his civilian pilot’s license.

He joined the Army in 1960, went to artillery school in Fort Sill, OK, and was assigned to the 4th Infantry Mechanized Battalion as a 155 Howitzer officer. He was transferred to Fort Rucker, AL, for flight training, where he remained after graduation as a flight instructor until his honorable discharge in 1964.

He enrolled in law school at the University of WY and graduated in three years with honors in 1967. He joined his brother Dale Holst in the practice of law in Colorado Springs, CO, with the firm Strand, Holstand Hilbert, later entering the general practice of law as a sole practitioner with special emphasis in probate and real estate law. He was a member of the Colorado Bar Association and Wyoming State Bar Association, which in 2017 recognized him as a Distinguished Service Member. In business, he was President and Operating Officer of Circle S Storage with his partner, Peter Hadjis.

While practicing law, he continued flying in his Cessna 182 and Luscombe 8A. He was a gifted mechanic and restored a 1956 DeSoto and 72 240Z, but his real passion was in his more than 30 restored tractors.

He continued his love of God’s creation with travels to see fin and blue whales in the St. Lawrence River, harp seals on the Iles-De-La-Madeleine, grey whales off Vancouver Island, brown bears in Katmai National Park, AK, and circumnavigating the Archipelago of Svalbard to see polar bears, walrus, and arctic fox.

He is survived by his brother Stanley in Dresden, TN, and numerous nieces and nephews.
