His co-development of Cubism alongside Georges Braque between 1907 and 1914 remains one of the most consequential ruptures in the history of Western art, collapsing multiple viewpoints into a single plane and severing painting's obligation to the visible world. He worked across painting, sculpture, printmaking, and ceramics with sustained ambition across seven decades. Major retrospectives were mounted at MoMA as early as 1939, and his work is held permanently at the Musée Picasso in Paris, MoMA in New York, and the Reina Sofía in Madrid. He died in France in 1973.
