Leonardo Torres Quevedo

Leonardo Torres Quevedo was a Spanish civil engineer, mathematician, and inventor who developed numerous engineering innovations related to aerial trams, airships, catamarans, and remote control, and who was also a pioneer in the fields of computing and robotics. In the 1890s he focused his efforts on analog computation; from his Laboratory of Automatics established in Madrid in 1907 he built El Ajedrecista in 1912, an electromagnetic device capable of playing a chess endgame, and he designed a special-purpose electromechanical calculator that conceptually foreshadowed floating-point arithmetic.
