On this day in 1881, Pablo Picasso, one of the greatest and most influential artists of the 20th century, is born in Malaga, Spain. Picasso's father was a professor of drawing, and he bred his son for a career in academic art. Picasso had his first exhibit at age 13 and later quit art school so he could experiment full-time with modern art styles. He went to Paris for the first time in 1900, and in 1901 was given an exhibition at a gallery on Paris' rue Lafitte, a street known for its prestigious art galleries. The precocious 19-year-old Spaniard was at the time a relative unknown outside Barcelona, but he had already produced hundreds of paintings. Winning favorable reviews, he stayed in Paris for the rest of the year and later returned to the city to settle permanently. The work of Picasso, which comprises more than 50,000 paintings, drawings, engravings, sculptures, and ceramics produced over 80 years, is described in a series of overlapping periods. His first notable period--the "blue period"--began shortly after his first Paris exhibit. In works such as The Old Guitarist (1903), Picasso painted in blue tones to evoke the melancholy world of the poor. The blue period was followed by the "rose period," in which he often depicted circus scenes, and then by Picasso's early work in sculpture. In 1907, Picasso painted the groundbreaking work Les Demoiselles d'Avignon, which, with its fragmented and distorted representation of the human form, broke from previous European art. Les Demoiselles d'Avignon demonstrated the influence on Picasso of both African mask art and Paul CEzanne and is seen as a forerunner of the Cubist movement, founded by Picasso and the French painter Georges Braque in 1909.
