Auguste Toussaint (1911-1987) began his career in 1932 as a librarian at the Carnegie Library in Curepipe before becoming the chief archivist of the National Archives of Mauritius in 1945. His first book Port-Louis, deux siècles d’Histoire, published at the age of 26, is the starting point for a considerable bibliography which includes more than twenty major books and numerous publications in journals and newspapers. Among his major works, it is worth mentioning his contributions to the Dictionnaire de Biographie Mauricienne that he started for the History Society of Mauritius, that he co-founded, and his work on Mascarene maritime routes and the privateers of the Indian Ocean, in particular La Route des île, Contribution à l’Histoire maritime des Mascareignes and Histoire des Corsaires. Initially a self-educated historian, he pursued university studies in parallel for many years and obtained the University of London Bachelor of Arts in 1945, a P.H.D. in Philosophy – History Section and graduated from the School of Librarianship and Archives in 1947. Besides his professional commitment both in Mauritius and abroad, Auguste Toussaint was also very active in the world of associations.
