The Turk
In Boston, Mälzel told a story that the New York chess players could not handle full games and that the Boston players were much better. This was a success for many weeks, and the tour moved to Philadelphia for three months. In Baltimore, it lost a match against Charles Carroll, a signer of the Declaration of Independence. Two American brothers built their own machine, the Walker Chess-player. Mälzel tried to buy it, but they would not sell it. This second machine toured for a number of years, but was never as famous as the Turk.
