Pablo Picasso was a prolific and influential Spanish artist who lived from 1881-1973. He helped develop modern art through his pioneering use of abstraction. Picasso made radical departures from traditional artistic styles and developed techniques like collage and papier collé. Throughout his career he worked in various mediums including painting, sculpture, ceramics, photography, and printmaking. In 1924, Picasso created some of the earliest examples of "light paintings" by moving light sources in front of a camera during long exposures.
