Pablo Ruiz y Picasso, also known as Pablo Picasso (October 25, 1881 - April 8, 1973), was a Spanish painter, sculptor, printmaker, ceramicist, stage designer, poet and playwright. As one of the greatest and most influential artists of the 20th century, he is known for co-founding the Cubist movement, the invention of constructed sculpture, the co-invention of collage, and for the wide variety of styles that he helped develop and explore. Picasso, Henri Matisse and Marcel Duchamp are regarded as the three artists who most defined the revolutionary developments in the plastic arts in the opening decades of the 20th century, responsible for significant developments in painting, sculpture, printmaking and ceramics. Picasso demonstrated extraordinary artistic talent in his early years, painting in a naturalistic manner through his childhood and adolescence. During the first decade of the 20th century, his style changed as he experimented with different theories, techniques, and ideas. Exceptionally prolific throughout the course of his long life, Picasso achieved universal renown and immense fortune for his revolutionary artistic accomplishments, and became one of the best-known figures in 20th century art. He died in 1973 at the age of 91. No artist credited, undated.
