Bill was born December 21st, 1944, in Milwaukee Wisconsin to William Frank Mortl, Sr. and Angela (Turk) Mortl. Bill was a proud U.S. Navy veteran and served in Washington DC. It was during this time that he met his wife. Bill married Linda Ellis from the Washington DC area in 1970 and they were married for over 54 years. In 1976, they welcomed their only son – William Michael Mortl. Professionally, Bill spent nearly the entirety of his career (30+ years) as a Mechanical Engineer for Caterpillar Tractor Company in Montgomery, Illinois.

Bill is survived by his wife Linda Mortl, his son William Michael Mortl (Karin Mortl), his two grandsons Henry and Caden Mortl, his two sisters Mary Fraser and Nancy Coughlin, his sister-in-law Sharon Wilke Mortl, as well as many nieces and nephews. It's difficult to describe a man's life that consisted of so many moments of quiet significance. Bill was well liked by the many peers he connected with over the years, and most importantly – he was loved by his wife and son. His passing has left a mighty void. He will continue to be loved and missed every day. A private memorial will be held at a later date.
