John Sartain
John Sartain , 1808-97, American engraver, b. London. Shortly after his arrival in the United States in 1830, he received important commissions for prints after paintings by leading artists. He is known for having introduced pictorial illustration as an important feature of American periodicals, most notably in Graham’s Magazine and in Sartain’s Union Magazine of Literature and Art, which he founded in 1849. He pioneered in mezzotint engraving in the United States, and produced many fine engravings after such painters as Benjamin West and Thomas Sully.
