Henry W. Minot, J.D.
Henry Whitney Minot III moved to Maine in 1989 where he managed financial and trust accounts and pursued interests in woodworking and photography. A childhood interest in minerals was rekindled during this period, and he attended his first major mineral show in 2007, where he made his first significant mineral purchase, a large tourmaline specimen from Mount Mica, Maine. Following that purchase he began to expand his knowledge of mineralogy and added to his collection with a focus on New England Minerals.  He began attending symposia in Rochester, NY and in Maine, and mineral shows from Tucson to Germany, England and France, meeting collectors, miners and geologists.  Combining his interests in photography and minerals he now concentrates on photographing his collection and exhibits the images on the worldwide mineral website mindat.com.  He currently lives in Edgecomb, Maine and joined the board of the Maine Mineral and Gem Museum in 2016.
