Famous Slovaks: Wolfgang von Kempelen
Wolfgang von Kempelen was born in Bratislava, and spent most of his life in Vienna, where he worked in the service of Maria Theresia, ruler of the Habsburg Empire.
Von Kempelen was quite simply a genius. Among his many achievements was the invention of a speaking machine (in 1791) and a special typewriter for the blind.
His most famous invention, however, was the construction of The Turk, a chess-playing automaton, which was later found out to be a hoax.
