In 1770, Hungarian engineer Wolfgang von Kempelen unveiled a miracle: a mechanical man who could play chess against human challengers. In this week's episode of the Futility Closet podcast we'll meet Kempelen's Mechanical Turk, which mystified audiences in Europe and the United States for more than 60 years. We'll also sit down with Paul Erdős and puzzle over a useful amateur. Intro: Lewis Carroll sent a birthday wish list to child friend Jessie Sinclair in 1878. An octopus named Paul picked the winners of all seven of Germany’s World Cup games in 2010. Sources for our feature on the Mechanical Turk: Tom Standage, The Turk, 2002.
