Happy Birthday William Sidney Mount!! This American painter was born in 1807 and came from a family of painters (one of three brothers who were painters). His family lived on a farm on Long Island. After an apprenticeship with his older brother, William became a portrait painter and genre scenes of life on the farm. After a short stint in New York, he returned to Long Island to settle in Stony Brook for the rest of his life. His style lends narration to scenes of American life in the 19th century.
