Jacques Cazotte

Jacques Cazotte, a French writer, born at Dijon in 1720, guillotined in Paris, Sept. 25, 1702. He became first known by a prose poem, Olivier, somewhat in the style of Ariosto's poems. Soon a number of tales, full of wit and originality, among them Le diable amoureux and Le lord impromptu, added to his fame. He was endowed with such facility and power of imitation that in one night he wrote a sequel to Voltaire's poem, La guerre civile de Geneve, and so perfect was the imitation that no one doubted the addition to be Voltaire's own. Cazotte in his later years became one of the most fervent adepts of Illuminism and Martin-ism. Being a faithful royalist, he was arrested during the revolution, and escaped death in the September massacres through the heroism and entreaties of his daughter Elisabeth, but was soon arrested again, condemned by a tribunal, and executed.

The statue of the "Flute Player " in the gardens of the Tuileries first suggested to him the project of making an automaton player, and he acquired great celebrity by works of that class. (See Automaton.) Cardinal Fleury appointed him inspector of silk manufactures, and in consequence of his improvements in machinery he was attacked by the workmen of Lyons; he retaliated by constructing an automaton ass weaving flowered silks. He bequeathed his collection to the queen, who gave it to the academy of sciences; it was scattered in consequence of a contest with the mercantile authorities for the possession of the manufacturing machinery, and Vaucanson's most celebrated automatons are now in Germany.
