Excerpt
The accompanying portrait of M. Gustave Trouve is taken from a small volume devoted to an account of his labors recently published by M. Georges Dary. M. Trouve, who may be said to have had no ancestors from an electric point of view, was born in 1839 in the little village of Haye-Descartes. He was sent by his parents to the College of Chinon, whence he entered the Ecole des Arts et Metiers, and afterward went to Paris to work in the shop of a clock-maker. This was an excellent apprenticeship for our future electrician, since it is in small works that electricity excels; and, if its domain is to be increased, it is only on condition that the electric mechanician shall never lose sight of the fact that he should be a clock-maker, and that his fingers, to use M. Dumas?s apt words, should possess at once the strength of those of the Titans and the delicacy of those of fairies. It was not long ere Trouve set up a shop of his own, whither inventors flocked in crowds; and the work he did for these soon gave up to him the secrets of the art of creating. The first applications that he attempted related to the use of electricity in surgery, a wonderfully fecund branch, but one whose importance was scarcely suspected, notwithstanding the results already obtained through the application of the insufflation pile to galvano-cautery. What the surgeon needed was to see plainly into the cavities of the human body. Trouve found a means of lighting these up with lamps whose illuminating power was fitted for that sort of exploration. This new mode of illumination having been adopted, it was but natural that it should afterward find an application in dangerous mines, powder mills, and for a host of different purposes. But the perfection of this sort of instruments was the wound explorer, by the aid of which a great surgeon sounded the wounds that Italian balls had made in Garibaldi?s foot.
