The influential artist known for the technique of cubism is Pablo Picasso. Along with Georges Braque, he developed this revolutionary art movement in the early 20th century, characterized by the fragmentation of objects into geometric shapes and the use of multiple perspectives. Picasso's works, such as “Les Demoiselles d'Avignon,” challenged traditional representations in art and paved the way for modernism. His innovative approach expanded the boundaries of visual expression, making him one of the most significant figures in the history of art.
