Pablo Picasso (1881 - 1973) was an artistic virtuoso who co-founded Cubism. He produced an astounding 20,000 paintings, prints, drawings and sculptures during his brilliant 70-year career. Picasso's body of work was so vast, and its phases so unique, that art historians have divided it into specific periods. His revolutionary Cubist works, with their distorted shapes and fragmented forms, established that art does not need to literally represent reality. Zealously embracing every medium from primitive art to sketches to Surrealism, Picasso had an unrivaled influence upon 20th century art.
