Don died Aug. 6, 2013, at the Merrimack Valley Hospice in Haverhill, Mass., from complications related to Kennedy’s disease, from which he had suffered for more than 20 years.
Don came to Princeton from the Salisbury School in Connecticut, where he sang in the choir and lettered in football, basketball, and baseball. At Princeton he majored in mechanical engineering and was a member of Dial Lodge. He continued his passion for singing with a voice scholarship each year, including one at Westminster Choir College his senior year. His roommates were Jay Cullen, Steve Dantzscher, Ray Kidani, and Bob Major.
After Princeton, Don built on his background in mechanical engineering to become an expert in operations research, supply-chain management, and inventory control. He achieved APICS certification and worked as a management consultant with several companies. A longtime resident of Andover, Mass., he sang in the choir and served as the cantor for several years at St. Robert Bellarmine Church.
Don is survived by Judy, his wife of 45 years; his daughter, Bethany; and his older brother, Richard Hajec. The class extends its deepest sympathy to all his family.
