Paul Cezanne (1836-1906) : Ignored during most of his life, but a massive influence on the direction of art after his death. Very original in style and technique, Cezanne loved playing with perspective and color to make things look unrealistic, but 'right'. He was the first to work mostly in flat geometric forms, the first to work in impressionist lighting into a realist style. Opened the door for cubism with his odd perspectives.
