Kenn Clark, an aeronautical engineer who had ably assisted Professor Robert Jahn ’51 *55 in running the electric propulsion laboratory at Princeton, died April 24, 2018. He was 79.

Clark graduated from the University of Michigan with bachelor’s and master’s degrees in aeronautical engineering in 1961 and 1962, respectively. He then earned a Ph.D. in mechanical and aerospace engineering from Princeton in 1969. For several years he helped administer the electric propulsion lab of the mechanical and aerospace engineering department.

Under Jahn, Clark assisted students at the lab, and was well liked and admired by them and colleagues alike. Later, he was with RCA Labs in Princeton, which eventually joined Lockheed Martin. Clark was a member of several satellite-launch teams.

His interests included attending sporting events, historic landmarks, space exploration, and his music collection. Since 1989 Clark had been a career-service volunteer for Princeton and an APGA member. He is remembered for his kindness and real interest in others. He contributed to the Graduate School’s Annual Giving campaign for 36 years.

Clark is survived by his wife of 57 years, Janet; three children; and four grandchildren.

Graduate memorials are prepared by the APGA.
