an early American portrait painter and engraver. Greenwood was born in Boston, Massachusetts in 1727. He apprenticed with Thomas Johnston, a sign painter and engraver from 1742 to 1745 where he copied various English works. Besides portraits, Greenwood painted many satirical works. He left Boston in 1752 and traveled to the Dutch colony of Surinam in northeast South America. He stayed there for over five years, during which time he executed 115 portraits, before traveling again, this time to Europe, arriving in Amsterdam in May 1758.
