One the most distinguished artists of the twentieth century, Jacob Lawrence was born in Atlantic City and spnt part of his child hood in Pennsylvania. After his parents split up in 1924, he went with his mother and siblings to New York, settling in Harlem. "He trained as a painter at the Harlem Art Workshop, inside the New York Public Library's 113 5th Street branch.
