Kohler was born February 20, 1939 to Ruth Miriam DeYoung Kohler (1906–1953) and Herbert Vollrath Kohler Sr. (1891–1968), who ran the Kohler Company from 1937 until his death. He is related to other former company Presidents, including Walter J. Kohler Sr. and Walter J.

In 1961, Kohler married Linda Karger, but the couple divorced in the early 1980s. Kohler appeared in the film Open Range (2003), which starred Kevin Costner, and received the role because he was a friend of Costner.
