North London Collegiate School. In 1895 she succeeded Miss Buss as headmistress of
North London Collegiate, serving until 1918. Sophie Bryant was a pioneer in education for women. She was the first woman to receive a DSc in England; one of the first three women to be appointed to a

When Trinity College Dublin opened its degrees to women, Bryant was one of the first to be awarded an honorary doctorate. She was also instrumental in setting up the Cambridge Training College for Women, now
