Who taught Pierre-Auguste Renoir at his painting studio in Paris?

In 1862, Pierre-Auguste Renoir took painting lessons at the studio of Charles Gleyre, a Swiss painter who had been a student of the 19th-century Neoclassical artist Jean-Auguste-Dominique Ingres.1

While Renoir found that Gleyre's academic style did not suit his own artistic vision, he accepted the discipline of the studio to acquire the fundamental skills necessary to become a professional painter. It was at this studio that Renoir met fellow students Alfred Sisley, Claude Monet, and Frédéric Bazille, with whom he formed a lasting friendship based on their shared desire to create art that was closer to life and free from traditional constraints.1
