West was born in Springfield, Pennsylvania, in a house that is now in the borough of Swarthmore on the campus of Swarthmore College, as the tenth child of an innkeeper and his wife. The family later moved to Newtown Square, Pennsylvania, where his father was the proprietor of the Square Tavern, still standing in that town. West told the novelist John Galt, with whom, late in his life, he collaborated on a memoir, "The Life and Studies of Benjamin West" (1816, 1820) that, when he was a child, Native Americans showed him how to make paint by mixing some clay from the river bank with bear grease in a pot. Benjamin West was an autodidact; while excelling at the arts, "he had little education and, even when president of the Royal Academy, could scarcely spell". One day his mother left him alone with his little sister Sally. Benjamin discovered some bottles of ink and began to paint Sally's portrait. When his mother came home, she noticed the painting, picked it up and said, “Why, it’s Sally!” and kissed him. Later, he noted, "My mother's kiss made me a painter."
