William Lewis studied at Parsons School of Design (both the New York City and Paris branches), Hunter College, where he earned his BFA, and New York University from which he graduated with his MA in 1992. After several years of working and exhibiting in New York, he moved to Boise in 1997. Following a stint as an adjunct professor in the Art Department at Boise State University, he began teaching art full time in the public school system. Lewis’ work has been exhibited in New York and in multiple venues in the northwest. His paintings have been included in three Idaho Triennial exhibitions at the Boise Art Museum (earning merit awards twice), and some are permanently installed in the Boise Public Library’s Hillcrest branch. Lewis’s work was also featured in the Sun Valley Center for the Arts' Making Camp exhibition. Exhibition reviews of his art have appeared in The Boise Weekly, Idaho Arts Quarterly, and in the internationally distributed magazine, Art in America. In 2019, Lewis had a solo exhibition, Adventures in Eveningland, at the Rosenthal Gallery, College of Idaho, Caldwell. He was a recipient of the 2011 Fellowship award from the Idaho Commission on the Arts.
