Dame Rose Heilbron (1914-2005; called 1939) was one of the country's most famous barristers. In 1949 she was one of the first two women to be made a KC (the other was Helena Normanton) and later she was the first woman judge to sit at the Old Bailey. In 1985 she was appointed the Inn's first female Treasurer.
