Philippe Henri de Girard patented in France spinning frames for both the dry and wet spinning of flax. His inventions were also patented in England in 1815, in the name of Horace Hall. Little is known about Horace Hall, it is a possible pseudonym. Undoubtedly if he had taken out his patent in England in 1815, the year of the Battle of Waterloo, in a French name there would not have been a lot of enthusiasm for it; possibly even suspicion. In the British Isles James Kay has been credited with the invention of this device. On 2 December 1826 shortly after Kay’s patent was awarded, Philippe Henri de Girard wrote to the Editor of The Manchester Guardian complaining about and pointing out he had been the inventor. The following is an extract from his letter: :"''A few months ago, a gentleman of the name of Kay, excited a strong sensation in the trade, by announcing a new method of spinning flax, by which much finer and better yarn was produced, than by any other process previously adopted. He announced this invention not only as new, but as his own; the results of his experiments were published in many provincial and London papers; and he granted to several flax-spinners, the right of using his invention, for which he obtained a patent''. :''The public will now hear, perhaps with some astonishment, that all this noise was made for a discovery long since published on the continent, and even patented in England twelve years ago. This new process of spinning, announced by Mr. Kay, is the same which I invented fourteen years since, and which is established, with great success, in France, Saxony, and Germany. A patent was taken out in England, in the month of May, 1815, by my partners in Paris, Messers. Cachard and Lanthois, in the name of Mr. Horace Hall''." It is probably not surprising that a French man, when France was at war with Britain, may have had to use a pseudonym when taking out a patent in England. ==References== Manchester Guardian, 2 Dec.,1826 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Horace Hall」の詳細全文を読む スポンサード リンク
