Caroline Fisher of Cambridge, and longtime summer resident of West Tisbury, died Saturday morning, August 28, at the Martha’s Vineyard Hospital.

Born Caroline McMurtrie Speer on August 10, 1922, in Wilkes-Barre, Pa., she was the first of three daughters born to Charlotte Rose Welles Speer and the Rev. Elliott Speer. She lived for a number of years in Northfield, where her father served as headmaster of the Mount Hermon School for Boys before his death in 1934. (A recent account of Reverend Speer’s death appears in Craig Walley’s book, Murder at Mount Hermon, The Unsolved Killing of Headmaster Elliott Speer, Northeastern University Press 2004.)

Caroline Speer graduated from Vassar College in 1944 and attended Union Theological Seminary in New York city from 1944 to 1945, where she served as a research assistant to the noted theologian Paul Tillich. In 1948 she married Roger Dummer Fisher.

They lived in Paris from 1948 to 1949 while her husband worked on the Marshall Plan, and then returned to live in McLean, Va., for nine years. In 1958, they moved to Cambridge when her husband joined the faculty of Harvard Law School.

In 1960 the Fishers purchased the Watcha Gun Club at Scrubby Neck in West Tisbury and began their 50-year association with the Island. In 1964 they hired Herb Hancock to build a new house nearby on Watcha Pond where they, their children and grandchildren have been summering ever since.

She is survived by her husband of 61 years, Roger Fisher, emeritus professor of law at Harvard University, of Cambridge; her sister Margot Goudsmit of Norwich, Vt.; her sons Elliott Speer Fisher of Norwich, Vt., and Peter R. Fisher of Maplewood, N.J.; and five grandchildren: Allegra, Kate and Josie, of Norwich, Vt., and Duncan and Charlotte of Maplewood, N.J.

A memorial service will be held on Oct. 2 at 2 p.m. at St. Barnabas Episcopal Church on Main street in Norwich, Vt.

In lieu of flowers or gifts, the Fisher family has requested that donations be made the Martha’s Vineyard Hospital Annual Fund, P.O. Box 1477, Oak Bluffs, Mass. 02557, noting that they are made in memory of Caroline Speer Fisher.
