Peter W. Hemmenway Obituary

Peter William Hemmenway of Swarthmore passed away peacefully on June 30, 2018 at the Hospital of the University of Pennsylvania.

Loving husband of Diana (Sophocles) and devoted father to his children, Michael and Andrea, Peter was co-founder and President of Hemmenway and Reinhardt, Inc., a Swarthmore-based accounting firm specializing in non-profit planned giving.

Peter was known for his steel-trap memory, dry humor, wise counsel, and devotion to family and friends. His integrity and reliability were his hallmarks. When he wasn’t working at the office, Peter pursued his passion for books, particularly novels written by first-time authors. His obsession extended to his “Book of Books” – faithfully carried in his back pocket in case he wandered or finagled his way into a bookstore seeking a discounted hard cover book. His other interests included good movies (also found in the back of his Book of Books), the Flyers, and the Phillies, especially on Dollar Dog Nights.

Born on December 13, 1945, in Wilmington, Del., Peter lived in Wallingford during his elementary school years prior to the family’s move to Summit, N.J. He graduated from Duke University and subsequently served as a 1st Lieutenant in the Army Infantry during the Vietnam War.

Peter and Diana, his wife of 38 years, met in Swarthmore at a mutual friend’s Christmas party in 1979. They remained in Swarthmore to raise their two children and establish Peter’s business. Prior to starting Hemmenway and Reinhardt, Peter worked in Philadelphia as Vice President in the Trust department of Fidelity Bank. It was this experience that developed his expertise in the specialized area of planned giving administration, and formed the basis for starting the firm with his founding partner, Edith Reinhardt. Due to Peter’s committed and long-standing relationships with clients, the firm is now in its 31st year supporting non-profits based locally, regionally, and nationally.

Peter is survived by his wife and son; his mother, Jane Hemmenway of White Horse Village, Pa.; and his two sisters, Lynn Smith (David) of Summit, N.J., and Nancy Hemmenway (Tom Welsh) of San Francisco, Calif.
