Ignace-Louis-Alfred Le Cointe (14 September 1823 – 18 June 1893, sometimes called Alfred Lecointe) was a French mathematician, mathematics teacher, and Jesuit priest.
Life
Le Cointe was born in Nîmes, attended the École Centrale in Paris at an unusually young age, and in 1847 joined the Jesuit order in Toulouse, and was sent to study philosophy in Vals. He taught mathematics at the seminary in Vals, at a college in St.-Etienne, at the École Sainte-Marie in Toulouse, and at the Institut Catholique de Toulouse. He died in Toulouse.[1][2]
