Richard Maxwell Dunn, a teacher, scholar, and banker who taught at the Ross School and East Hampton High School, died of pancreatic cancer on Friday in New York City. He was 70 and had been ill for 15 months.
Mr. Dunn, who lived full time in Springs since 2003, followed an unusual career path. He received a B.A. from Dartmouth College and a Ph.D. in French literature from Yale University. From 1969 to 1974, he was a French professor of the University of Chicago.
