[Picture: Van Gogh's self portrait ] Vincent Willem van Goghwas a Dutch Post-Impressionist artist. His paintings and drawings include some of the world's best known, most popular and most expensive pieces. Van Gogh spent his early adult life working for a firm of art dealers. After a brief spell as a teacher, he became a missionary worker in a very poor mining region. He did not embark upon a career as an artist until 1880. Initially, van Gogh worked only with sombre colours, until he encountered Impressionism and Neo-Impressionism in Paris. He incorporated their brighter colours and style of painting into a uniquely recognizable style, which was fully developed during the time he spent at Arles, France. He produced more than 2,000 works, including around 900 paintings and 1,100 dr...more >>awings and sketches, during the last ten years of his life. Most of his best-known works were produced in the final two years of his life, during which time he cut off part of his left ear following a breakdown in his friendship with Paul Gauguin. After this he suffered recurrent bouts of mental illness, which led to his suicide.
