Susan Sutherland Isaacs, CBE (née Fairhurst; 24 May 1885 – 12 October 1948; also known as Ursula Wise) was a Lancashire-born educational psychologist and psychoanalyst. She published studies on the intellectual and social development of children and promoted the nursery school movement. For Isaacs, the best way for children to learn was by developing their independence. She believed that the most effective way to achieve this was through play, and that the role of adults and early educators was to guide children's play.
