Louis-Marin Bonnet French, 1736 - 1793
French engraver and publisher. He came from a family of artisans and owed his training in engraving to his brother-in-law, the engraver Louis Legrand (1723-1808). Through Legrand, Bonnet became the pupil of Jean-Charles Francois in 1756, a year before the latter discovered the CRAYON MANNER technique of engraving, designed to reproduce the effect of a coloured-chalk drawing. Around the end of 1757 Bonnet used the new technique to engrave a Cupid after Francois Eisen. Gilles Demarteau, a rival of Jean-Charles Francois
