Mademoiselle Souvestre founded the girls’ boarding school Allenswood, outside London, where her most famous pupil was Eleanor Roosevelt who went on to become one of the most respected women of the 20th century.
Eleanor’s early life was marked by an alcoholic father and a vain and distant mother (both of whom died before she was ten), and she was sent abroad to boarding school.
Mademoiselle Souvestre was the headmistress of the preparatory school to which young Eleanor was sent. Fortunately, Mademoiselle Souvestre’s goal for her students was to expand their minds and attain intellectual independence. The school used French in many classes. Eleanor turned out to be better prepared than most for Allenswood, due to extensive French tutoring prior to enrolling.
According to Elizabeth Pearce of MentorResources, it was during this period that Eleanor lost her shyness and acquired the self-confidence which would stand her so well in later life. Mademoiselle Souvestre mentored Eleanor, and they made field trips to Venice and Paris, with Eleanor making the arrangements. Mentoring introduced the teenager to the lifestyle of an independent woman. Eleanor always credited Souvestre with forming both her character and her intellectual outlook. The First Lady’s newspaper column on politics and social issues, My Day, was read daily by millions.
