Along with his parents, in April 1912 Widener boarded the "Titanic" at Cherbourg, France bound for New York City. As the ship sank Widener's mother and her maid were rescued, but Widener, his father, and his father's valet perished. In 1915, Widener's mother donated the Harry Elkins Widener Memorial Library to Harvard in his memory. Two buildings at the Hill School are also dedicated to Widener, and stained glass windows at St. Paul's Episcopal Church, Elkins Park, Pennsylvania are dedicated to Widener and his father.
