After Princeton, where he was baseball captain and president of the Student-Faculty Association and the Westminster Society, he taught biology at Andover for 17 years, was headmaster of his prep school, Shady Side Academy, for 12 years, and head of the lower school at Albuquerque (N.M.) Academy for seven years. A highlight for Flop was spending 94 of his 96 summers at Lake Chautauqua in western New York, where he was active for more than 60 years in Sunday services and was an honorary trustee of the Chautauqua Institute. In 1984 he wrote, “While it has been my pleasure and honor to be on many church and civic boards, my close ties with Chautauqua have made my efforts there ‘a labor of love.’ Indeed, it is there I will be buried.”
Flop was married in 1945 to Julianne “Julie” Barnum, who survives him. Also surviving are a daughter, Caran Redington, and her husband, Bill; a son, Geof ’74, and four grandchildren.
