Mary Whitmore McClintock of Concord, MA died peacefully on November 6th, 2013 at the age of 92. Born on July 24th, 1921 in Greenfield, MA, to Philip F. Whitmore and Martha R. Whitmore, she grew up on the family farm in North Sunderland and was taught by the same school teacher as her father. Without a high school in town, Mary attended Northfield School for Girls and later Wellesley College '42 as had her mother, Martha R. Whitmore '20, her grandmother Mary H. Richardson 1887 and later her daughter Martha '69. She met her husband of 66 years, the late Professor Frank A. McClintock, at a square dance getting to know him on joint Wellesley-MIT Outing Club trips. They were married on September 10th,1944, receiving their guests on her parent's lawn in front of the family waterfall. Mary and Frank moved to Pasadena, California, shortly returning to become one of the original settlers of the progressive Conantum housing community in Concord. As a farm child, Mary spent much of her childhood alone outdoors and roamed the forests, streams and fields of her family farm, showering under waterfalls and swimming from "the rocks" in the Connecticut River. From her mother she learned the night sky and to "bird by ear", from her father the native plants, geology and work on the farm. From this arose a deep, abiding and comforting connection with nature. Her belief of the importance of land preservation for generations to come led her to dedicate some of the woods surrounding her family farm in Sunderland for land conservation. Mary wrote her senior thesis on the "ecosystem" of Observatory Hill at Wellesley College, 12 years before the first ecology textbook was published. Then, having minored in mathematics, Mary was hired by the Statistics Department at Employers Liability Assurance Company (the only woman there with a college degree) and was sent to International Business Machines (IBM) to learn how to code (i.e. physically wire) "computers". MIT's Center of Analysis recruited her to be their Assistant Supervisor of Analysis and code a secret wartime project, which she figured out was predicting the weather and was later used for D-Day. She then moved to Pratt and Whitney Aircraft in Hartford, CT. She eagerly embraced the rise of computers, first for writing and later sleuthing answers on the internet for her family and friends. With her love of numbers, she served for over 25 years as the treasurer of the Women's Parish Association of the First Parish Meetinghouse in Concord, and also for the Thoreau Lyceum and the Conantum Garden Club. A competitive swimmer, she became manager of the Wellesley College Swim Team, taught swimming and water safety at the YMCAs, colleges, and later at Walden Pond. Her love of the outdoors also led her hiking, camping, canoeing, skiing, gently walking through the woods and climbing through alpine gardens above timberline in Colorado during her many summer family trips out west. Mary became the legendary "nature lady" teaching field natural history courses for the Thoreau Lyceum, the Concord Public Schools and Concord Adult Education, leading children and adults in her classes around Walden Pond, sharing her in in-depth knowledge of Thoreau's journals, typically walking and pausing in the same places that Thoreau wrote about. Concord, with its heritage of naturalists and transcendentalists, was an ideal place for her to explore her many interests. She strongly believed that environmental education was for all ages, teaching nature in the First Parish nursery school, elementary, junior and high schools throughout the greater Boston area as well as college courses. Mary and a number of local women were also leaders of the "Birds Go to School" program, for which they caught wild starlings and brought them into classrooms in the inner city to show students before letting them go out the window. She also trained teachers at the Elbanobscot Foundation and last, but not least, developed "Armchair Naturalist", a course for older adults, ranging in age from 80 to 94. Mary would sit outdoors for hours simply noticing all that came to her through sight, sound or touch. She delighted in finding the first shoots of spring, songs of returning birds, peepers, the coming of fall and life in winter. Regardless of the season she would bring back to the house a variety of flowers, pine cones, dried seeds or leaves. At other times she would go out exploring, often taking the road unknown. She could not pass a dirt road without turning in to see what secrets it held. She would gather the family in the car and drive to a nearby hill to watch the sunset and smell the apple blossoms. Mary had a wonderful curiosity about life near and far. She loved learning about Unitarian Universalism; Judaism, and many other religions, getting on her hands and knees looking for worms from a robin's eye view, or discovering the meaning of a new word. She enriched the Concord Chorus with her harmonious alto voice. Mary brought family, friends and strangers into her warm embrace with the telling of stories and her impish sense of humor. She treasured her many friends, including meeting weekly with women neighbors in Conantum under the cover name, "The Sewing Group", which carries on to this day. Mary is survived by Martha and her husband Joel Charrow of Chicago, IL and their children Ben and his wife Caroline, and Julia and her daughter Makayla; Roger and his wife Jane Jeffries, presently on the high seas off Philippines; David and his wife Nancy of Lyman, ME and their daughter Sue; and Rich and his daughters Charlotte and Rayna of Denver, CO. Mary was a cohesive matriarch for both sides of her extended family and a loving sister to the late Carolyn Shilling of Kingston, RI and her brother William Whitmore of Sunderland. Condolences to the family may be sent to the McClintock family c/o Newbury Court, 80 Deaconess Road #341 Concord, MA 01742. Tributes may be posted at deefuneralhome.com.
