Jacques Benard, improperly said Robert Bénard was a French engraver born in Rosny-sous-Bois in 1731 and died in Paris in 1794. He signed 60% of the Encyclopedia engravings and took part in other monumental editions, like Cook’s voyages or the Methodical Encyclopedia, for which he directed a team of 60 people. Thanks to research in the National Archives, in the parish records of the Seine Saint-Denis archives, as well as in the manuscript records of the longitude office, more facts about his life are known.
