In the late 1500s a Nuremberg man named Frantz Schmidt began to do something utterly remarkable for his era: he started keeping a journal. But what makes Schmidt even more compelling to us is his day job. For forty-five years, Schmidt was an efficient and prolific public executioner, employed by the state to extract confessions and put convicted criminals to death. In his years of service, he executed 361 people and tortured, flogged, or disfigured hundreds more. Is it possible that a man who practiced such cruelty could also be insightful, compassionate, humane—even progressive?
