Pablo Ruiz Picasso (25 October 1881 – 8 April 1973) was a Spanish painter and sculptor who spent most of his adult life in France. One of the 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. Among his most famous works are the proto-Cubist Les Demoiselles d'Avignon (1907) and the anti-war painting Guernica (1937), a dramatic portrayal of the bombing of Guernica by German and Italian air forces during the Spanish Civil War. His career spanned more than 76 years, from his late teens to his death in 1973.

Arguably Picasso's most famous work is Guernica, asked to explain its symbolism, Picasso said, "It isn't up to the painter to define the symbols. Otherwise it would be better if he wrote them out in so many words! The public who look at the picture must interpret the symbols as they understand them."
