(b Windham, CT, 6 April 1783; d New York, 16 Feb 1861). American painter. After attending a country school and working on his father’s farm, he decided at the age of 16 to become an artist. He took lessons from Joseph Steward (1753–1822), a retired minister who operated a portrait studio in Hartford, CT. Waldo opened his own studio in Hartford in 1803, before moving on to paint portraits in Litchfield, CT, and Charleston, SC. In 1806, bearing letters of introduction to Benjamin West and John Singleton Copley, Waldo travelled to London, where he studied at the Royal Academy. His portrait of Mr M’Dougle (untraced) was shown at the Royal Academy in 1808.
