SALLY WALLER read Modern History at Oxford University and has subsequently devoted her life to education, through teaching, examining and writing. She has produced many history textbooks for a range of publishers in the course of her career and, most recently, has been the editor and part-author of a popular Advanced Level History series for Oxford University Press. She has also contributed articles to educational journals and has pursued a number of independent research projects. Her recent retirement after many happy years as a History teacher at the Cheltenham Ladies’ College has given her the opportunity to combine her historical and educational interests through this study of that College’s pioneering Principal.
