Marvin Hewitt never finished high school, but he taught advanced physics, engineering, and mathematics under assumed names at seven different schools and universities between 1945 and 1953. In this week's episode of the Futility Closet podcast we'll trace the curious career of an academic impostor, whose story has been called "one of the strangest academic hoaxes in history."

We'll also try on a flashproof scarf and puzzle over why a healthy man would check into a hospital.
