William Coperthwaite was a native of Maine who traveled the world in search of folk-art techniques and subsistence skills. Impressed by the beauty and intelligence of the traditional central Asian nomadic tents called "yurts," Coperthwaite adapted and introduced to North America yurt design and construction. For four decades he participated in building more than three hundred yurts for family homes, schools, camps, and outbuildings. Awarded a doctorate from Harvard University's School of Education for his work with Eskimo villagers, Coperthwaite taught in a variety of innovative educational settings. William passed away unexpectedly in late 2013. His organization, the Yurt Foundation, continues to serve to promote sensible and economical self-reliance through workshops, lectures, and publications.
