Hollis Nichols

Hollis Nichols was born and raised in the Greater Boston area spending his boyhood summers on the family farm in Hollis, NH. He was an Alumni, Treasurer and Trustee of Roxbury Latin School in Boston MA. He conceived the idea of affiliating Beaver Brook with Roxbury Latin to provide an outdoor natural science experience for the urban school.

Hollis had a passion for land stewardship practices and land protection. His particular interests in agriculture, horticulture, and land protection were demonstrated by his generous contributions to Beaver Brook over the years. The organization was started with his donation of the Nichols family summer home and surrounding 18 acres. Along with his wife Ellen, Hollis established funds dedicated to acquiring future parcels of land for Beaver Brook.

His other passion was fostering a greater awareness and appreciation of our heritage through innovation and practical restoration of old buildings. One excellent example is the Maple Hill Farm home of the Beaver Brook offices and its complex of buildings.
