William Schlumberger (1800 – April 1838) was an Alsatian chess master. He is known to have taught
Pierre Charles Fournier de Saint-Amant to play chess and as the operator of The Turk, a chess-playing machine which was purported to be an automaton. It was Bavarian musician and showman Johann Nepomuk Mälzel who hired him to operate The Turk.  Schlumberger acted as the Turk's director in Europe and in the United States until his death from yellow fever in 1838.

Biography
The main source of information on Schlumberger's life is  Willard Fiske's book of the first American chess congress and, in particular, the section dedicated to “The history of the Automaton Chess-Player in America”. The brief biography given below is, unless otherwise indicated, taken from that publication.

Schlumberger was born in Mulhouse, Alsace, a region often fought over by France and Germany. He belonged to a wealthy family, and attained a very high education. He was considered very strong in Mathematics and he spoke not only French and German with which, as an Alsatian, he was equally familiar from childhood, but also in English. His own account of himself was, that he had entered upon the business life, for which he had been so carefully educated, in Paris, where he and his brother were put in charge of the dépôt of the family establishment at Mulhouse. He was thrown out of business by a commercial misfortune, and then he began to support himself by giving lessons in Chess at the Café de la Régence. At the Café, he was one of the leading players, but was known there only by the name of Mulhouse a nickname given to him, probably, by Saint-Amant. When St. Amant, began to frequent the Café de la Régence, about the year 1823, he found Mulhouse,  capable of playing with La Bourdonnais at no greater odds than the Pawn and move, and fully equal to Boncourt and Mouret. Therefore, the young St. Amant took chess lessons from him. Many years later, he gratefully acknowledged that to Schlumberger he owed his first initiation to chess.

The subsistence of Schlumberger, dependent solely upon his earnings as a Chess-teacher, was undoubtedly precarious. For this reason, he accepted the offer of Maelzel, the owner of The Turk, to operate the Chess-Automaton during its tour in America for fifty dollars a month plus travel expenses.
During the tour, however, there were some incidents that almost revealed the secret of the Automaton.
In Baltimore, two boys, secreted on a roof, saw the figure of Schlumberger come out of the machine. An article, "The Chess-Player Discovered," appeared in the Baltimore Gazette on Friday, June 1, 1827, exposing the matter.
Later, in Richmond, the Turk was observed by Edgar Allan Poe, who later wrote his essay "Maelzel's Chess Player" published in April 1836. He observed:

There is a man, Schlumberger, who attends him wherever he goes, but who has no ostensible occupation other than that of assisting in the packing and unpacking of the automaton. This man is about the medium size, and has a remarkable stoop in the shoulders. Whether he professes to play chess or not, we are not informed. It is quite certain, however, that he is never to be seen during the exhibition of the Chess Player, although frequently visible just before and just after the exhibition. Moreover, some years ago Maelzel visited Richmond with his automata, and exhibited them, we believe, in the house now occupied by M. Bossieux as a Dancing Academy. Schlumberger was suddenly taken ill, and during his illness there was no exhibition of the Chess Player. These facts are well known to many of our citizens. The reason assigned for the suspension of the Chess-Player's performances, was not the illness of Schlumberger. The inferences from all this we leave, without farther comment, to the reader.

On November 9, 1837, Schlumberger and Maelzel sailed to Havana, Cuba. There, Schlumberger contracted Yellow Fever and died in April 1838.

Chess games

The previously quoted book of the first American chess congress describes Schlumberger as a rapid Chess-player, but not particularly strong in the endgame. It also adds some details about his opening repertoire:

When the Automaton adhered to its claim of the first move, the game was made a gambit; when the adversary had the move, Schlumberger invariably resorted to Mouret's favorite defence of King's Pawn one—a Boeotian defence, thoroughly understood at the Cafe de la Regence—so often played afterwards by La Bourdonnais, so thoroughly detested by McDonnell In playing end-games, Schlumberger did not come off quite so well: he was sometimes beaten, although very seldom.

A very few and rare games of Schlumberger games survived, however. The following game, lost by the Automaton, is not particularly well played, but it has a certain historical importance being, possibly, the first published game by an American woman chess player. Here it is presented with the comments of C. H. Stanley

Mrs. F - The Turk (Schlumberger)
Philadelphia, 1827
1. e4 e6 Most of our readers, we presume, are aware that the Automaton was a Turk; had he been a Christian, he surely would not have played "K. P. one" against a lady. 2. Nc3 d5 3. Qf3 Nf6 4. Bd3 An eccentric style of move, but by no means bad play under the circumstances 4...c5 His "Turkship" has not yet discovered the dexterity of his fair antagonist; expecting to achieve an easy
victory he considers it beneath his dignity to take care of his Pawns. 5. b3 Bd6 6. exd5 exd5 7. Nxd5 Nxd5 8. Qxd5 O-O 9. Bb2 Mrs. F. shows a thorough knowledge of the peculiar position under which her various Pieces will act most favorably. There is more natural genius displayed by her in the conduct of this game than is met with in by far the greater portion of the games which
come under our notice. 9... Nc6 10. a3 Be6 11. Qe4 g6 12. O-O-O Qd7 13. h3 Bf5 14. Qf3 Bxd3 15. Qxd3 Rae8 16. Nf3 a6 17. g4 b5 18. c4 We like the boldness and decision of Mrs. F.'s style of play; this is true Chess. Blue Beard will shortly make the unwelcome discovery that he has for once at least "caught a Tartar". If the ladies of his own country possessed the characteristics evinced by Mrs. F., their position would be far different from that which it now is. 18...bxc4 19. Qxc4 Rb8 20. Kb1 Qb7 21. Qc3 Threatening an immediate
checkmate. 21...Nd4 Badly played; his only chance to save the game would be to push King's Bishop's Pawn one square 22. Nxd4 Be5 Play as he will, he must now lose a Piece, as, should he take Kt. with Pawn, Mrs. F. would take Pawn
with Queen, and in order to avert the checkmate then threatened, it would be necessary to abandon the Bishop to his fate. 23. Qxc5 Bxd4 24. Qxd4 f6 25. Qc4+ Kg7 26. Ka2 Rfc8 27. Qa4 Rc2 28. b4 Qd5+ 29. Qb3 Qe4 30. Rhe1 Qc6 31. Rc1 Rxc1 32. Rxc1 Qd6 33. Rd1 a5 34. b5 a4 35. Qxa4 Qd5+ 36. Qb3 Qc5 37. d4 Qg5 38. a4 Qf4 39. Qg3 resigns. Never was better account rendered of Infidel and Saracen, on the sandy desert of his own soil, than is now given by the fair champion of Christendom of her unbelieving foe, on the chequered field of his own battle-ground.

Willard Fiske gave the following explication of Schlumberger's poor play during this game.
Maelzel's first exhibition-season in Philadelphia extended from 26 December 1826, to 20 March 1827. The Hall was open twice a day—at noon and in the evening—and full games as well as end-games were played, but whether indifferently at either hour I do not know. The Automaton lost one end-game—the famous Three Pawn position—to Mr. Daniel Smith; and one full game to a lady, Mrs. Fisher. The latter game happens to be the only specimen of poor Schlumberger's play—I will not say skill—that has been preserved. It was printed at the time in the Philadelphia Gazette, and was afterwards reported in Mr. Stanley's American Chess Magazine (p. 57). It was played at two different sittings, on the 30th and 31st days of January. Maelzel's devotion to the fair sex was quite too profound to allow his Automaton to insist upon his prerogative to take the first move; nay, Schlumberger is said to have had peremptory orders to get beaten. After the lady's 39th move, Mr. Maelzel (says the newspaper), at this stage of the game, considering it lost, politely thanked Mrs. F., and observed that he was fairly beaten. He also remarked that the Automaton had been conquered but three times—once in Paris, once in Boston, and by Mrs. F. of Philadelphia.

The other of Schlumberger's games which has survived is probably more interesting. It was played with Charles Vezin (1781–1853), considered the founder and father of chess in Philadelphia and a good player.
The notes to the game  are from Chess in Philadelphia: a brief history of the game in Philadelphia edited by G. C. Reichhelm and W. P. Shipley, 1898. Additionally, analysis carried out with the chess engine FireBird 1.2 are reported in square parentheses.

C. Vezin - W. Schlumberger
Played in Philadelphia at a private party between Mr. Charles Vezin and Maetzel's Automaton Chess Player. It took three sittings, starting January 15, 1827, continuing January 22 and finishing January 23.
1.e4 e6 2.Bc4 Not well opened.
