Jack died of heart trouble Aug. 11, 2007.
He grew up in Port Washington, N.Y., and attended the Lawrenceville School. At Princeton he majored in mechanical engineering, rowed on the varsity crew, and was a member of Cannon Club.
During World War II Jack worked for the government as a civilian in California and Canada, where he was secretly involved in anti-aircraft and bombsight technology. He helped to create the "DEW Line" early-warning system in Canada.
After the war, Jack joined the family freight-forwarding business from which he retired in 1984, and moved to Cocoa Beach, Fla. His lifelong passion was speedboat racing. He was the on-board mechanic for the 1940 Gold Cup winner. For $50 Jack, with a friend, bought a Gar Wood runabout and, after repairing it, won many races. Jack was inducted into the Gulf Oil Motorboat Racing Hall of Fame in 1952.
Jack was married to Alice Rose of Astoria, N.Y., who died in 2000. He is survived by his son, Fritz; a daughter-in-law, Leslie; granddaughter Joanna; and a nephew, Dr. Robert F. Pickels '63. The class extends its heartfelt condolences to them all.
