Pierre-Auguste Renoir (February 25, 1841–December 3, 1919) was a French artist who was a leading painter in the development of the Impressionist style. As a celebrator of beauty, and especially feminine sensuality, it has been said that "Renoir is the final representative of a tradition which runs directly from Rubens to Watteau".

Pierre-Auguste Renoir is a famous French impressionist painter, associated with the Impressionism movement along with his friends Claude Monet, Alfred Sisley, and Frédéric Bazille.

Renoir was born in Limoges, Haute-Vienne, France, on February 25, 1841 as a child of a working class family. Renoir’s first encounter with painting dates from his childhood he worked in a porcelain factory where his drawing talent led to him painting designs on China.
From the beginning in early 1860s when Renoir started studying art under Charles Gleyre in Paris, when he didn't have enough money to buy paint, to his last day when rheumatoid arthritis severely hampered his movement and he was forced to paint by strapping a brush to his arm, and created sculptures by directing an assistant who worked the clay, Renoir's painting was always beautiful and optimistic! So was his view of life and his painful condition. The pain passes, but the beauty remains was Renoir's words.

Renoir's paintings are probably the most popular, well-known, and frequently reproduced images in the history of art. Almost everybody has heard of the Bathers, The Umbrellas, Luncheon of the Boating Party and one of the most expensive paintings ever, Le Moulin de la Galette along with many other. They present a vision of a forgotten world, full of sparkling color and light. Renoir once said: Why shouldn't art be pretty? There are enough unpleasant things in the world.
