Constructed by Charles Godfrey Gumpel (c.1835 - 1921), an Alsatian manufacturer of artificial limbs, it took some 6 or 7 years to build and was first shown in 1878 at Gumpel's home in Leicester Square, London. Mephisto was mainly operated by chess master Isidor Gunsberg.
Mephisto consisted of a life-size figure of an elegant devil, dressed in red velvet and seated in an armchair in front of an ordinary table, where the chessboard was sited. The chessboard had indentations on each square to hold the bases of the chessmen to prevent them from moving. The figure was bolted to the table to enable its arm to reach across the board.
It was the first automaton to win a Chess tournament when it was entered in the Counties Chess Association in London in 1878 and at one time had its own chess club. In 1879 Mephisto, with Gunsberg, went on tour, defeating every male player. When playing ladies, however, Mephisto would first obtain a winning position before losing the game then courteously offer to shake their hand afterwards.
When Mephisto was shown at the Paris Exposition of 1889 it was operated by Jean Taubenhaus. After 1889 it was dismantled and its subsequent whereabouts are unknown.
Mephisto was later used as the name of a top-line dedicated chess computer which won the World Microcomputer Chess Championship in the years 1985-1990. The name is now used by the consumer electronics company Saitek on its line of standalone chess computers.
