He stayed on at Princeton after our undergraduate years to earn a master’s degree in chemical engineering. He then spent 18 years in research and development with Union Oil Co. in California. He said his most significant assignment with Union Oil was 20 months spent in Colorado working on an oil shale demonstration project.

Chuck’s first marriage ended in 1963. A second marriage also ended after two years, in early 1969. By then he had joined Kerr-McGee Oil in Oklahoma City, Okla. Later in 1969 he met and married his third wife, Barbara. In our 25th-reunion yearbook, he reported, “It seems I more than lucked out after the previous two attempts. This marriage has not had a bit of trouble. And now, at 47, I’m a new father!”

Chuck died June 1, 2017. He is survived by his wife, Barbara; their daughter Sarah; and his brother Gordon ’49.
