This man's algebraic machine used an "endless spindle" to compute the sum of log a plus b in order to  find the roots of polynomials.
This man's algebraic machine used an "endless spindle" to compute the sum of log a plus b in order to  find the roots of polynomials. He described how to improve upon Babbage's designs by using  electromechanical devices in his "Essays on Automatics." His telekino was a remote controlled boat. He  designed the Whirlpool Aero Car at Niagra Falls and the Astra airships used by France in WWI. His most  famous invention dates to 1912 and used a king and rook against king end game. For 15 points, name this  Spanish inventor of the first documented real chess playing automaton.
