About this Item
Jb. k.k. polytech. Inst., 14. - Hrsg. Johann Joseph Prechtl. - Wien, Gedruckt und verlegt bei Carl Gerold, 1829, 8°, VI, 410 pp., mit acht Kupfertafeln, orig. Broschur. Erstdruck! "Der Erfinder glaubt, indem er diese Maschine bekannt macht, daß dieselbe das Interesse, welches sie haben kann, mehr in der Sonderbarkeit als ihrer Nützlichkeit verdankt; weil sie, obschon theoretisch zur Auflösung von Gleichungen aller Grade geeignet, sehr enge Grenzen in der parktischen Ausführung findet, und nur mit Schwierigkeit für mehr als fünf Grade, oder einige darüber in Anwendung kommt." "In 1826-27 Girard was in London to present a new invention of his, a calculating machine, to the Royal Society but was disappointed to hear that Babbage had recently made a presentation of a similar machine. A tract was published in 1827 to explain the differences between the author's and Babbage's machines, a copy of which is held in the Royal Society achives (Equations machine invented by Ph. de GIRARD "(a description with figures) London : John Churchill, 1827). PHILIPPE HENRI DE GIRARD (1775-1845) , "French mechanician, was born at Lourmarin, Vaucluse, on the 1st of February 1775 . He is chiefly known in connexion with flax-spinning machinery . Napoleon having in 18ro decreed a reward of one million francs to the inventor of the best machine for spinning flax, Girard succeeded in producing what was required . But he never received the promised reward, although in 1853, after his death, a comparatively small pension was voted to his heirs, and having relied on the "money to pay the expenses of his invention he got into serious financial difficulties . He was obliged, in 1815, to abandon the flax mills he had established in France, and at the invitation of the emperor of Austria founded a flax mill and a factory for his machines at Hirtenberg . In 1825, at the invitation of the emperor Alexander I. of Russia, he went to Poland, and erected near Warsaw a flax manufactory, round which grew up a village which received the name of Girardow . In 1818 he built a steamer to run on the Danube . He did not return to Paris till 1844, where he still found some of his old creditors ready to press their claims, and he died in that city on the 26th of August 1845 . He was also the author of numerous minor inventions." Encyclopedia Britannica 1911. Seller Inventory # 48725
