Mary M. Campbelldied May 19, 2012 at Brookside Nursing Home due to complications from Alzheimer's. Born in Hanover, NH September 14, 1940, she was the daughter of Clarence and Edith Campbell, who preceded her in death.

Mary graduated from Hanover High School in 1958 and Wellesley College in 1962 with a B.A. in art history. After graduation, Mary joined the Peace Corp and spent 2 years in Venezuela. Later she moved to Boston, MA where she was employed at The Architects' Collaborative and at Eisenberg and Schiffer Architects. During this time she continued her education studying architecture and planning at the Boston Architectural Center.

Mary then moved to Haverhill, NH and cared for her mother for several years. After the death of her mother, Mary was employed at the Montshire Museum of Science and later the Cold Region Research Engineering Labs. She served as a volunteer for many community programs including the Haverhill Library Association, Bedell Covered Bridge, Inc., Haverhill Historical Society, Haverhill Planning Board, Thresholds program at the Grafton County Jail, and Retired Senior Volunteer Program (RSVP).

Mary greatly enjoyed entertaining and was famous for slow cooking, with many gourmet meals served into the night. She was interested in many arts and crafts especially weaving, knitting, and sewing. At her home on the Haverhill Common she raised sheep for wool, grew plants for dyes, and spun yarn. She also collected a remarkable selection of fabric, yarn, and patterns for any occasion as well as literature on crafts and historical topics. For years Mary joined neighbors for a morning walk around the Haverhill Common and Court Street.

Mary was married to William (Bill) Koch, Jr. who died in 2009. She is survived by her sisters, Ann Campbell of Somerville MA and Elizabeth Campbell (Gregory Hill) of Seattle WA, and her niece Caroline Hill of Washington DC.
