Wikipedia: Pablo Picasso
Pablo Ruiz y Picasso, also known as Pablo Picasso (/pɪˈkɑːsoʊ, -ˈkæsoʊ/; Spanish: [ˈpaβlo piˈkaso]; 25 October 1881 – 8 April 1973), was a Spanish painter, sculptor, printmaker, ceramicist, stage designer, poet and playwright who spent most of his adult life in France. 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.
