Leo Herman Wolf:  June 29, 1931 – August 1, 2025

Born and raised in Minneapolis, Minnesota, Leo started life in North Minneapolis attending Ascension Catholic School on the northeast side.  Catholic education was always important to Leo and he met many lifelong friends along the way. He moved from Ascension to Annunciation Church and School in South Mpls for the remainder of his grade school years. From there he went on to De La Salle High School, graduating in 1949.  His college years were at St. John’s University and the University of Minnesota graduating from the U of M, School of Architecture with a Bachelor of Arts in 1954.

In 1954, Leo married Darcy Rae Mitchell, who he met during his grade school years.  He began his career in architecture working at several different firms before starting his own firm in the mid 1960’s. In addition to his love for architecture he started another company with his (dentist) brother Hugo, to design and manufacture dental treatment rooms and the equipment for them.  When that business became successful in the early 1970’s he decided to focus on Time Motion System Company exclusively. Here he was able to use his design skills, as well, to assist dentists with building layouts. As a compliment to the dental equipment Leo also invented a water purification system for dental unit water lines called DentaPure.

Leo and Darcy Rae were married for 20 years and had four children. During these early years, Leo was active with AIA (American Institute of Architects), Serra Club (a Catholic men’s club),  and his children, including Boy Scouts and High School Parents Club activities,  After Darcy Rae’s sudden death in 1975, Leo married Margorie McNabb in 1976 and moved his life to River Falls Wisconsin where Marge was the local travel agent.  Leo and Marge enjoyed the next nineteen years building a home, working, traveling, and entertaining.

After Marge’s death in 1993, Leo reconnected with Betty Sue, whom he also had known well as a child in grade school and high school. They married in 1995 and were together until 2021 when Betty Sue passed away. Betty Sue brought seven more children into the family which enhanced Leo and Betty Sue’s many adventures and family holidays. Leo thoroughly enjoyed his role as patriarch and friend to a very large family of children, grandchildren, and great-grandchildren.

Leo is survived by his sisters, Rita (Tom) Culshaw and Mary Ann (Jose) Baraibar; his  four children, Mark (Laurie) Wolf, Darcy (Kevin) Hedrich, Kathleen (Charles) Kusilek, Gerald (Caroline) Wolf; Betty Sue’s children, Dr. Walter (Maura) Halloran, Elizabeth (Alan Levin) Halloran, Teresa (Tim) Martin, Mary (John) Bartek, Dr. John (Dr. Carol) Halloran, Michael (Danette) Halloran, Joseph (Kristi) Halloran; 26 grandchildren; and many great-grandchildren.  Leo was preceded in death by his brother, Hugo; his first wife, Darcy Rae (Mitchell) Wolf; and his second wife, Margorie (Carpenter McNabb) Wolf; Betty Sue (Fredericks Halloran) Wolf; and granddaughter, Christina Wolf.
