At Princeton Donald majored in electrical engineering and was active in numerous foreign student and engineering associations. He joined Wilson Lodge his senior year. He earned a master’s degree in applied mathematics at Brown University in 1963 and joined Westinghouse Electric Co. in its corporate research and development department. He spent his entire career with Westinghouse, first in computer applications and later in management-information systems, retiring in 1999.
In 1976 Donald married Yuling Li, a Wellesley graduate. They had one daughter, Evelyn, who predeceased him. Donald continued an active involvement with the Pittsburgh Chinese community. By Yuling’s account, he became an excellent cook, a keen gardener, and a Steelers fan. But their greatest enthusiasm was for travel — river cruises and tours throughout Europe, New Zealand, China (of course), and safari in Africa.
Sadly, Donald suffered with Alzheimer’s in his last years and died as the result of a fall on Aug. 1, 2020. He is survived by Yuling, who has our sympathy.
