Jacob Van der Schley (1715 - 1779) was a prominent Amsterdam engraver and draftsman based out of Amsterdam.  Schley apprenticed under portrait engraver Bernard Picart, whose style he imitated.  He is said to have completed several of Picart's portraits following his master's death.  While Schley is primarily known for his work as a portraitist and illustrator, he also has a considerable cartographic corpus.  He is known to have worked with Bellin, Hondt, and Provost, among others.
