Claire Drawing Room Signed Chevallier Pont Neuf Paris Nineteenth Box

Clear chamber* for drawing in brass, signed "Maison de l'Ingénieur Chevallier** Opticien, Place du Pont-Neuf 15 Paris", in its original box, from around 1830, first half of the 19th century. This clear room is in its own juice. The optics are missing. A note: traces of oxidation on the brass, wear of time, look at the photos. We put another clear bedroom for sale on this site. ** Chevallier (1778-1848): engineer-optician to the Prince of Condé, one of the members of the famous family of opticians established since 1765 (Louis-Vincent Chevallier) on the Quai de l'Horloge in Paris. Known as the Engineer-Chevallier since 1740, he himself opened a shop at the corner of Pont-Neuf. We owe him many inventions and improvements in the manufacture of a wide variety of instruments, instruments of experimental physics, experimental optics, chemistry, astronomy, mineralogy, surgery, etc. which were manufactured and found in the workshops and stores of the house of Charles-Chevalier, engineer. He now occupies a shop at 17 rue des Pyramides where he perpetuates the tradition. __________________________________________________________ *A camera lucida (in Latin camera lucida) is an optical device used as a drawing aid by artists and patented in 1806 by William Hyde Wollaston. The camera lucida performs an optical superposition of the subject to be drawn and the surface where the drawing must be transferred. The artist uses this layering to place key points of the subject to be reproduced, or even its outline. The perspective is reproduced perfectly, without construction. The prism including a 45° surface, the image is inverted as with a mirror.
