Bronson Pinchot, an Audie Award-winning narrator and Audible's Narrator of the Year for 2010, received his education at Yale University, which filled out what he had already received at his mother's knee in the all-important areas of Shakespeare, Greek art and architecture, and the Italian Renaissance. He restores Greek Revival buildings and appears in television, film, and on stage whenever the pilasters and entablatures overwhelm him.
