Upon graduation he remained at Princeton to earn a master’s degree and work for the Department of Aeronautics and Mechanical Engineering as a lecturer and research associate at its Forrestal facility that specialized in the study of hovercraft vehicles.
In 1958 Marc married Meredith “Merry” McLaughlin, a Bryn Mawr graduate who was the daughter of Roland McLaughlin, dean of the School of Architecture. Marc and Merry bought an old farmhouse on a 100-acre property along the D&R canal and they were very much a “faculty couple,” their home serving as a social center for students and friends. They traveled widely and were active on the local tennis circuit as well as in several community organizations. They also built a vacation cottage amid a colony of Princetonians on the Caribbean island of Culebra and, on Marc’s retirement, they moved to a family home in Newagen, Maine. Marc died there March 20, 2020.
