Ed met his future wife, Judy Connelly, on a blind date. Having graduated from the University of North Carolina, Ed returned to the Philadelphia area to join his father and brother, Harry Coslett, in a family stevedoring business, E.W. Coslett Sons. He subsequently worked in real estate, owning several apartment complexes and contributing to other real estate development projects in Delaware County. Ed and Judy remained married for 69 years, and raised three children in Swarthmore. In 1977, they left Swarthmore to live on a family farm in Newtown Square for 31 years, and spent their final years at Dunwoody Village.
Ed was predeceased by his wife, his brother, and his eldest son, Edward W. Coslett III. He is survived by a son, Branch Coslett, and daughter, Judith Addavail Coslett, as well as 10 grandchildren and 14 great grandchildren.
Ed had a passion for American history and a longtime devotion to the Chesapeake Bay, where he spent much of his childhood. His family remembers him as a devoted and loving husband, parent and grandparent with a kind and generous nature.
