Dan died of acute myelogenous leukemia (AML) July 11, 2011, in Glenmoore, Pa.

He graduated from Lawrenceville. At Princeton, where his father was in the Class of 1905, he majored in civil engineering and belonged to Cloister. He spent a term working in civil engineering construction and graduated in 1951.

During the Korean War he was signal officer on the USS Sanborn and subsequently taught at the Amphibious Force Operational Intelligence School.

For our 25th, he wrote that after “15 years of bachelorhood with lots of sculling, skiing, and fishing,” he married Deborah Dunn.

Early in his career, Dan turned to consulting engineering in commuter and high-speed railway projects. He was the design manager of the Philadelphia Airport High Speed Line Railroad and participated in the initial planning for the Washington, D.C., regional transit system, the Northeast Corridor high-speed railway service, and high-speed service between Philadelphia and Harrisburg.

Dan retired in 1988 and moved from suburban Philadelphia to Glenmoore. There he became deeply involved with the township’s planning issues and management of water resources. In retirement, he enjoyed hunting with his wire-haired Bassets, hiking, and gardening.

Our sympathy goes to Deborah; daughters Reed and Alexandra; a nephew, Henry ’83; and four grandchildren.

Undergraduate Class of 1950
