Art Nouveau was an art movement that took place in Europe between 1890 and 1910. It emphasized natural forms and organic lines inspired by nature. Important Art Nouveau artists included Aubrey Beardsley, Gustav Klimt, Henri Toulouse-Lautrec, and Alfons Mucha. Klimt focused on symbolist painting and is famous for works like The Kiss. Toulouse-Lautrec created hundreds of paintings and posters in just 20 years, helping to define the style. Mucha was known for his stylized posters of beautiful women.
