Pablo Picasso was a Spanish painter, sculptor, and one of the most influential artists of the 20th century. He is best known for co-founding the Cubism movement, which revolutionized European painting and sculpture by breaking objects into geometric shapes and presenting multiple perspectives simultaneously. Throughout his prolific career, Picasso created thousands of artworks, including famous pieces like Guernica and The Weeping Woman. His innovative approach and diverse styles, ranging from the Blue Period to Surrealism, have left a lasting impact on modern art and continue to inspire artists around the world.
