Instrument maker.
The Musée des Arts et Métiers have on display a form of dividing engine used for engraving series of accurately-space lines on printing plates, designed by Nicolas-Jacques Conté and constructed by Antoine-Clerc Gallet in 1803. See here and illustrations on this page. Conté was responsible for a publication on Napoleon's Egyptian campaign, and wishing to reduce the cost of producing the plates for printing the illustrations, he proposed using a machine to assist in engraving. It would engrave parallel lines, more or less pronounced, graduated to vary the density of the tones. The publication of the Description de l’Égypte in twenty volumes took place from 1808 to 1822. Gallet constructed the machine.
