W H E N I STARTED work on this life of the two friends and pioneers of girls’ education in this country, Frances Mary Buss and Dorothea Beale, I went first to the official biographies, Frances Mary Buss by Annie Ridley, published in 1895, and Dorothea Beale of Cheltenham, published in 1908. Both books contain lengthy extracts from correspondence and personal sketches, and in the case of Miss Beale from a manuscript autobiography and a private diary. Unfortunately this material was subsequently destroyed and I have had to treat these published quotations as original sources. I have, therefore, only used footnotes to indicate the source of additional unpublished material and magazine articles, etc. Miss Beale was a prolific writer and her books, particularly her History of the College, have helped me much. So, too, have two recently published books, The North London Collegiate School 1850-1950-Essays in Honour of the Centenary of the Frances Mary Buss Foundation; and Miss A. K. Clarke’s History of the Ladies College 1853-1953.
