With her husband, Knight founded the Jacob and Gwendolyn Knight Lawrence Foundation in 2000, initially to support the early careers of professional artists. When Lawrence died, Knight disbanded the original foundation and changed her will so that most of the couple's assets went to support children's programs. Today the Foundation's activities are devoted to the maintenance of a website that had been developed in 2000. The U.S. copyright representative for the Jacob and Gwendolyn Knight Lawrence Foundation is the Artists Rights Society.
