William (Bill) George Koch, 93, passed away peacefully on May 7, 2018. Bill was born in Forsyth, Mont., on May 16, 1924, to Harry and Margaret (Holmes) Koch who preceded him in death.

Bill and Jeanette (Woltermann) Koch met on Mother’s Day, May 8, 1949. They were married at St. Mary’s Catholic Church in Columbus, Mont., on October 20, 1951. They have four children. This was their 67th year of marriage.

As a youth, Bill’s family homesteaded and farmed in southeast Montana (Sumatra, Mont., and later in Fishtail, Mont.). Upon the advice of his parish priest, Bill applied for admission to the University of Notre Dame in 1942, later graduating with a bachelor of science in chemistry in 1947. During his time at the University of Notre Dame, he was drafted into the United States Army and served in World War II until he was honorably discharged in 1946. He later received a master of science degree from the University of Montana and ultimately his PhD in Physical Chemistry from the University of Illinois. Dr. Koch went on to become a chemistry professor at the University of Northern Colorado (formerly Colorado State College) for 29 years, retiring in 1984.

He then embarked on a second career at the Wyoming Public Health Crime Analysis Laboratory as an expert witness in blood sample testing, retiring (for real this time) in 1996. For many years, Bill volunteered at St. Peter Catholic Church, with the Kiwanis Club of Greeley (he was instrumental in rehabilitating Kiwanis Park in downtown Greeley) and at the Room-at-the-Inn, providing shelter for families in need.

He was also a third degree Knight of the Knights of Columbus. He was as compassionate as he was intelligent and no one was a stranger to him. He enjoyed spending time with his kids and grandchildren, playing card games (especially Pinochle) and gardening. He always had a project in the works and brought many of his inventions to life.

He was a son, brother, husband, father, grandfather, friend, teacher and mentor but most importantly he was a man with a strong faith in the Lord.

Bill is survived by his wife Jean, sister Rena Koch (Billings, Montana); son Nick (Susan), of Champaign, Ill., and their children Andy, Caroline and Chris; son Greg (Ann) of Fort Collins, Colo., and their children, Benjamin and Henry; son Steve, (Shellie) of Greeley and their children Kylie, Haylie and Zach; daughter Carol (Tony) Landretti of Greeley and their daughter Gianna.

Mass of Christian Burial was 2 p.m. Monday, May 14, 2018, at St. Peter Catholic Church followed by interment at Linn Grove Cemetery.
