Paul Dupuy, History Lecturer at Paris' École Normale Supérieure, published in 1896 the first scientific biography of the mathematician Évariste Galois, titled "La vie d'Évariste Galois". He attended the École Normale Supérieure at rue d'Ulm, Paris. His schoolmates included the future geographers Marcel Dubois and Bertrand Auerbach, and the future historians Georges Lacour-Gayet, Salomon Reinach and Gustave Lanson. In the 1890s, Dupuy was a prominent defender of the unjustly convicted Jewish French officer Alfred Dreyfus. He was the father of Marie-Thérèse Maurette.
