Born in Mineola, N.Y., Dual prepared for Princeton at St. Peters Preparatory in Peekskill, N.Y., where he participated in football, track. and school publications. At Princeton he played freshman football and joined the Yacht Club. Dual majored in chemistry and joined Elm Club. His preferred pursuits beyond chemistry and club life were sailing, skiing, and swimming.
Sadly, Dual did not contribute to our 10th, 25th, and 50th yearbooks and none of the usual other sources for information on his life after Princeton have yielded anything. He lived on Nantucket at the time of his death, leaving his wife, Anna; and a son and daughter and their families.
