The last surviving member of the class was Edmund De Treville Ellis. Commissioned in the cavalry, he later transferred to the Quartermaster Corps, with which he served in the European Theater during World War II and during the 1948 Berlin airlift. He retired from the Army as a colonel on 31 March 1950. He became the oldest living graduate of West Point in October 1990, and the last surviving member of the class of 1915 on the death of Van Fleet. He died at the age of 104 on 22 January 1995. Like Van Fleet, he was interred in Arlington National Cemetery.
