Mark died Jan. 17, 2012, at his home, surrounded by his family.

Born in Chicago, he came to Princeton from Bloom Township (Ill.) High School. At Princeton, he joined Quadrangle Club and was a member of the Prince staff. He withdrew from the University in June 1959 and graduated from the University of Michigan with a bachelor’s degree in politics in 1963. He earned an M.P.A. in public administration and urban studies at Syracuse in 1966.

After short stints in San Francisco and Philadelphia and six months in Europe, Mark and his wife, Hope, moved to Vermont in the late 1960s. In 1972, he joined the Rutland Regional Planning Commission, rising to lead it as executive director in 1983, a position held until illness forced him to resign this year. He saw the commission as an enabler for local planning. “The most important thing is to listen to people,” he is quoted as saying, “to understand where they are, to help them articulate where they want to be, and to assist them in drawing the roadmap to get them there.”

He is survived by Hope, whom he married in 1967; sons Tycen and Jorden; five grandchildren; one great-grandchild; and his brother, Stephen.
