François-Joseph Lange of Maltière

François-Joseph Lange , knight of Maltière , born with Rouen in 1730 is a Physicien French.

Lange of Maltière was useful a long time, with the rank of captain of infantry, with the regiment of Dolphin, where its control deserved to him the title of knight of the order of Saint-Louis. This impassioned amateur of sciences, the letters and arts, that its memorandums describe like “ very poor officer, but very large physicist, naturalist, enough geometrician, in an academic prone word who would be employed much better in an academy than in a regiment ”, indeed cultivated those in his moments of leisure as long as its military career lasted.

As soon as it was withdrawn from the service, Lange of Maltière could be devoted entire to its scientific research. Occupying much physics in the part which is attached to optics, its principal merit is to be the inventor of a solar microscope, to which it gave the name of Physitechniope . Quoted with praise in the Newspaper of Trévoux of July 1753, this microscope was, in 1781, counterfeited, under the name of “mégascope”, by the famous physicist Charles to which one allotted the invention of it, but, in 1787, Mr. Sorel published a Mémoire in which it showed the undeniable rights of Maltière to discovered which was wrongfully denied to him.

Lange of Maltière communicated to the Académie of Rouen several Science reports, among which: Construction and use of a solar microscope , 1751; On the ground suitable to manufacture the porcelain , 1767; On a siphon precipitating , 1770; vertebral Petrifications , 1771; Paper of Tahiti, pays by Bougainville , 1772; Telescope of Dolon , 1772; universal Magic lantern , 1785; microscopic Reader , 1787.

The author of these Memories, who had also talent for poetry, left in manuscript a Épître in Eglé on his talents , a extremely remarkable Ode on Happiness , the legend of saint Jean-Baptiste and a héroï-comic poem on Paule de Viguier, famous woman, known under the name of the Beautiful Paule, born with Toulouse, at the beginning of.

He was accepted member of the Académie of Rouen and judge-academician of that of the Palinod S of the same city.
