Pablo Picasso (1881 - 1973), Spanish painter and sculptor of the twentieth century; the most famous and influential of all modern artists. He co-founded a type of art called Cubism which sought to illustrate the concept that everything in naturecan be reduced to the cube, the cone and the cylinder. Later works in this style entirely did away with any trace of realism in painting and sculpture. —PDC Volume 4 Approved Glossary
