Bill was born in Rochester, Minnesota March 1, 1929, the son of Margaret and Lawrence Nietz. He attended grade school in Rochester and high school in Savanna, Illinois where his father worked in a munition factory. Bill was in the army during the Korean War and after discharge, he came back to Rochester where he worked as a manager at the Jewel T grocery store. After a few years he started working at the Mayo Clinic. He was on general service for several years and then moved to the Division of Education and eventually became the first Mayo Clinic medical meeting planner. He helped plan meetings on and off campus. Working with Mayo staff was something he thoroughly enjoyed. Bill was married to Lois Klabunde, a nurse at Methodist Hospital, on March 30, 1957. Bill loved fishing, gardening, cooking, following the Twins and U of M basketball and football, and enjoyed providing reading assistance to students at local grade schools.
