Georges Braque 1908 reveals that the effect of his encounter with Picasso was more to accelerate and intensify Braque’s exploration of Cézanne’s ideas, rather than to divert his thinking in any essential way.” Braque’s essential subject is the ordinary objects he has known practically forever. Picasso celebrates animation, while Braque celebrates contemplation. Thus, the invention of Cubism was a joint effort between Picasso and Braque, then residents of Montmartre, Paris. These artists were the style's main innovators. After meeting in October or November 1907, Braque and Picasso, in particular, began working on the development of Cubism in 1908. Both artists produced paintings
Georges Braque throughout Paris and then Europe. The two artists' productive collaboration continued and they worked closely together until the beginning of World War I in 1914, when Braque enlisted with the French Army. In May 1915, Braque received a severe head injury in battle at Carency and suffered temporary blindness. He was trepanned, and required a long period of recuperation. Braque resumed painting in late 1916. Working alone, he began to moderate the harsh abstraction of cubism. He developed a more personal style characterized by brilliant color, textured surfaces, and—after his relocation to the Normandy seacoast—the reappearance of the human figure.
