William "Bill" Charles Cassebaum

William Charles “Bill” Cassebaum, 95, of Ann Arbor, Michigan, passed away at home, surrounded by his family, on Sunday, September 13, 2026. He was born on July 24, 1931, in Wilson Borough, Pennsylvania, to Merrill and Helen (Sullivan) Cassebaum.

In 1956, Bill married the love of his life, Janet Kendrick. They shared 66 wonderful years together until her passing in 2022.

Bill graduated from Easton High School in 1949 and from Lafayette College in 1953, where he was a member of the Phi Gamma Delta fraternity and captain of the track and field team. Bill was lifelong supporter of Lafayette athletics. He served as a trustee of Lafayette College, was elected Secretary of the Board and later was elected as trustee emeritus.

He went on to earn his law degree from the University of Michigan Law School in 1956, where he was a member and president of the Phi Delta Phi legal fraternity. After law school, Bill served in the U.S. Army until 1958.

Bill returned to Pennsylvania and began a distinguished legal career. He practiced law in Bangor, Pennsylvania for more than 40 years. Bill’s leadership extended well beyond his law practice. He served as President of the Northampton County Bar Association, and held key leadership roles in the Pennsylvania Bar Association. His leadership culminated in his election as the 98th President of the Pennsylvania Bar Association (1992-1993). He also served as a judge on the Pennsylvania Court of Judicial Discipline, and was a fellow of the American College of Trust and Estate Counsel.

Bill retired in 1998 and moved to Ann Arbor, Michigan with Janet, where they embraced the Ann Arbor and University of Michigan communities. They belonged to the Ann Arbor City Club and were supporters of the arts in Ann Arbor and at the University. He and his wife were active supporters of the University of Michigan’s School of Music, Theatre & Dance. Bill was also a devoted fan of all Michigan athletics.

Beyond his professional accomplishments, Bill found joy in an active life. He was an ardent skier and tennis player. Later in life he enjoyed golf with friends and family. His enduring ties to Lafayette and Michigan reflected a lifelong commitment to the institutions, communities and people who shaped his journey. Above all else, he was devoted to his family and cherished as a beloved father and grandfather.

Bill is survived by his daughters, JoAnn Weisel (John) and Ellen Geldbaugh (Mark); grandsons Peter Weisel (Kelsea) and Thomas Weisel (Carly); and granddaughter Shen Geldbaugh.

The family wishes to express their sincere gratitude to the staff and caregivers of Home Instead Ann Arbor for their compassionate care and kindness.

Bill was laid to rest at Forest Hill Cemetery in Ann Arbor in a private family service.
