Ignace-Louis-Alfred Le Cointe (14 September 1823 â 18 June 1893, sometimes called Alfred Lecointe) was a French mathematician, mathematics teacher, and Jesuit priest. He wrote textbooks about trigonometry and conic sections and a book of problems at the secondary level.
Le Cointe was born 14 September 1823, in Nîmes, to a devout and illustrious family. He had an early interest and aptitude for exact sciences, so was sent to Paris to attend the ÃÂcole Centrale at an unusually young age. In 1847, joined the Jesuit order, and was sent to study philosophy at the seminary in Vals. He taught mathematics in Vals, at the Collége Saint-Michel in Saint-ÃÂtienne, at the ÃÂcole Sainte-Marie in Toulouse, and at the Institut Catholique de Toulouse. He died in Toulouse.
