Susan Isaacs made a significant impression on the world of early childhood education during the first half of the twentieth century. She ranks alongside Froebel and Dewey, as one of the pioneers of child-centred education. As Jody Hall has written, "the life, work and legacy of Isaacs serve as a witness to the value of the curiosity of children." She also enjoyed respect from beyond the academic community. Between 1929 and 1936 her contributions to the magazine "The Nursery World," as "agony aunt" Ursula Wise, were much appreciated. This article describes Isaacs' life, work and legacy.
