Don came to Princeton from Loveland, Colo., where in high school he lettered in football, wrestling, and track and was sports editor of the school newspaper.

At Princeton he majored in religion and was active with Orange Key, the Concordia Society, and crew.

After graduation, Don studied at the Duke Divinity School and then, when drafted, served in Army Intelligence at Fort Holabird, Md. By our 10th reunion he had found the passion of his life in environmental science. He obtained a Ph.D. in marine science from William & Mary.

In 1989 Don and Cathy were married and moved to Sarasota, Fla., where she taught at the New College of Florida and Don became the director of information technology at Mote Marine Laboratory. He retired from Mote in 2006 as a senior vice president.

Don and Cathy moved to Beech Mountain, where they nurtured each other in sickness and in health. Don was a prodigious birder and ecologist.

Don is survived by his wife, Catherine Stewart Elliott; and daughter Lauren Nicole Miller Hayward ’05. The class offers condolences to his family.
