Jack died of stroke complications on Nov. 5, 1999, at the age of 78.
Born in Ecuador and raised partially in New Jersey and Texas, he was one of the original organizers of the Outward Bound School.
Jack prepped at St. Paul's. On campus he was a member of Ivy Club. During WWII he fought with the OSS, operating behind Japanese lines in Burma.
A graduate of Columbia law school, Jack practiced business law in Denver from 1950-71. He later became an executive with the Oil Shale Corp. He served as chief legal officer, acquired two of its major refineries, and ran its coal division.
Jack availed himself of the many friendships he had made while training with the 10th Mountain Division at Camp Hale, Colo., to bring into being the famed Vail Ski Resort.
In 1950 he married Helen B. Chenery, with whom he had four children. A divorce ended that union in 1973. In 1980 Jack married Marjorie Sargent, who survives him. Also surviving are two daughters, Sarah Manning and Katharine McGrath, two sons, Christopher and John Jr., his sister and her husband, Dr. and Mrs. Edwin M. Sykes Jr.
To the entire family we offer our deepest condolences.
