Pierre Auguste Renoir did not start his career being a great artist. He started his art career as a teen when he was apprenticed to a porcelain artist, where he learned how to paint on the porcelain dishware. Then he took free drawing lessons which was run by Louis-Denis Caillouette. A couple years later, Renoir became a student of Charles Gleyre, another artist, at Gleyre's studio. There he met Claude Monet, Alfred Sisley, and Frédéric Bazille, and he also met Camille Pissarro and Paul Cézanne.
His first time revealing his art was in 1864 when he get into the Paris Salon exhibit in Paris where he showed his early realism paintings "La Esmeralda" and then the next year he showed another painting, a portrait of Alfred Sisley's father, William Sisley.
But in the year 1870 he was drafted into the war but fell ill with dysentery. His good friend Frédéric Bazille died in that same year.
After the war in 1871, he and old friends such as Claude Monet, Camille Pissarro, and Edgar Degas helped create the Impressionist movement, which in very short later time included artists such as Mary Cassatt, Paul Cézanne, Berthe Morisot, and more.
