Mephisto
Taubenhaus was a primary operator of the remote-controlled Mephisto chess player machine. The third automaton Mephisto was made by Charles Godfrey Gumpel, and unlike its predecessors The Turk and Ajeeb, it had no hidden operator and functioned by electro-mechanical means. Gumpel took a few years to build it and it was first shown in 1876 at his Leicester Square home in London. It was the first automaton to win a chess tournament when it was entered in the Counties Chess Association at London in 1878. Mephisto was operated by Isidor Gunsberg in the main. It was shown regularly for 10 years, and at one time had its own club in the UK. When Mephisto went to the Paris Exposition in 1889 it was operated by Taubenhaus. After 1889 it was dismantled and its subsequent whereabouts are unknown.
