A major figure in the art movement known as Cubism was Pablo Picasso. He, along with Georges Braque, developed this revolutionary style in the early 20th century, characterized by fragmented forms and multiple perspectives. Cubism broke away from traditional representation in art, allowing for a new way of seeing and interpreting reality. Picasso's work during this period, including masterpieces like "Les Demoiselles d'Avignon," has left a lasting impact on modern art and continues to influence countless artists today.
