John W. Hess IV was born November 6, 1945, in Brigham City, Utah, son of John W. Hess III and Thelma Maxine Dunning, fifteen years into their marriage. His mother became so violently ill that she thought she had a tumor. The doctor told her she had a tumor alright–a two-legged one. They lived on a ranch in northern Utah, in a house with 3 rooms and a path until John was 9 years old, when they moved into Tremonton.
