Kerry William Purcell has written books and essays about photography, film, design, philosophy, and critical theory. He's the author of biographies on Alexey Brodovitch and Josef Muller-Brockmann and is a senior lecturer in design history at University of Hertfordshire. In this episode, Jarrett and Kerry talk about how he found himself writing designer biographies, why he doesn't like to call himself a design historian, and how design can be a lens to ask questions around culture, politics, and history.
