The popular conception of Dame Laura Knight is of an energetic woman piling on the paint in the back of a huge and antiquated Rolls-Royce at Epsom Derby, the door propped open to the view, or charging off in pursuit of gypsies, clowns or ballerinas. A widely popular and successful artist, she painted people in action in a robust, realistic style, and was able to compete with men on their own terms, managing to get herself elected to that hitherto almost entirely masculine preserve, the Royal Academy.
