Trenchard More Jr.

1930 - 2019

Trenchard More, Jr. of Keene, NH, died peacefully on October 4, 2019 at age 89 surrounded by his loving family. Trenchard was born in Boston and raised in Hingham, where his family had a longstanding connection to Old Ship Church. He received his bachelors degree in mathematics from Harvard and a doctorate in electrical engineering from M.I.T. before teaching at Yale University in the 1960s. He was an early contributor to the field of artificial intelligence and developed Array Theory, the mathematics of nested interactive arrays. His work took him to IBM, and internationally to Queens University in Canada and the Technical University of Denmark. Trenchard married Kath- arine Grinnell Biddle of Milton in 1958. They took their family up Mount Katahdin, spent summers on the Elizabeth Islands, and went skiing in the Green Mountains, in addition to cultural forays to New York City. When grand- children arrived, Trenchard gathered his family for many summers on the coast of Maine. His love of natural beauty was echoed in his appreciation for the music of Stravinsky. Trenchard is survived by his beloved wife Kate, son Paul More and his wife Elizabeth of Concord, son Grinnell More and his wife Linda of Jacksonville, daughter Libby Pratt and her husband Neil of London, and six grandchildren. A memorial service in his honor will be held at Old Ship Church on October 20, 2019 at 2:00 PM. Donations in his memory may be given to: Old Ship Church, 107 Main Street, Hingham, MA 02043.
