One of his most influential experiences was his semester abroad with the English-Speaking Union. It led to repeated travel to England and several long friendships. His senior-year roommates were Joe Bacheller, Walt Barry, and Jim Hurlock.
After graduation he enlisted in the Navy. He then joined Gulf Oil, and in 1959 married Kathleen “Kay” Johnson, whom he had known in high school. They settled in New Canaan to raise their four children, Michael, Chris, Jean, and Kathleen. Don joined Quantum Chemical and became treasurer and vice president, before retiring in 1988.
Don and Kay lived for a while in Washington, Conn., where they had space for farm animals, family, and grandchildren who came to call him Pedro. Don immersed himself in a Princeton mentoring program, worked with at-risk students, and enjoyed local politics. Princeton was a lasting influence on his life.
Don is survived by Kay, their four children, and 12 grandchildren.
