Frederick Lum Trowbridge ’35 *44
Fred Trowbridge died on Apr. 20, 1989, in Klamath Falls, Oreg., to which he had moved in 1985 to be nearer his family. For more than ten years, Fred struggled with cancer, but he kept active, visiting family and friends across the country, downhill skiing, and riding his mountain bike, until the last two years of his life. His dedication to his family and his courage in pursuing all that life offered were inspiring to those who knew him.
Fred was born on July 6, 1914, in Chatham, N.J. The youngest of 11 children, he was orphaned before he reached school age and was raised by his mother's sister, a seamstress in Newark, N.J. She placed him in Grace Church Choir School and Trinity School, in N.Y.C. His undergraduate career was interrupted by the Depression, but he returned to Princeton in the early '40s and completed both his B.S. and M.S. (in chemical engineering) in 1944. He then joined Union Carbide and worked in technical plant design and chemical sales until the early '70s, when he became a part-time consultant for the Idaho Power Commission, in Boise.
A loyal supporter of Princeton, Fred returned with his family for many reunions, including the grand 50th in 1985. The class extends its sympathy to his wife of 50 years, Betty Ward; their three children, Joan Wayland, Frederick '64, and John (Yale '67), all of whom have M.D. degrees; and seven grandchildren. Col. Schuyler D. Ferris '36 and Roderick S. Ferris '74 are cousins.
