Leonard Schenk Janszoon (February 26, 1696 - June 11, 1767) was a Dutch engraver, the son of Petrus Schenk (Pieter Schenck) the Elder (1660 - 1711). Leonard was bornin Amsterdam and was tough engraving in his father's workshops. Most of Leonard's work focused on geography and architecture, but he also has a significant corpus of portraiture. Leonard engraved several maps and also carried on his father’s relationship with engraving plates for the Amsterdam edition of the Histoire de l'Académie Royale des Sciences. Leonard inherited neither his father's publishing legacy or business, all of which went to his older brothers, but remained a prolific private engraver in the Amsterdam trade through the late 18th century.
