William Hart (March 31, 1823 June 17, 1894), was a Scottish-born American landscape and cattle painter, and Hudson River School artist. His younger brother, James McDougal Hart, was also a Hudson River School artist, and the two painted similar subjects. He studied under Jules-Joseph Lefebvre. Hart was born in Paisley, Scotland, and was taken to America in early youth by his family. He was apprenticed to a carriage painter at Albany, New York, and his first artistic experience was in decorating the panels of coaches with landscapes. He also spent time as a portrait painter. He returned to Scotland, probably in the early or mid 1840s, where he studied for three years.
