Pieter Cornelis Mondriaan was a Dutch painter born in 1872 who pioneered abstract art. He began his career painting realistic landscapes but evolved through fauvism and divisionism after being influenced by artists like Jan Toorop, Jan Sluyters, Edvard Munch, Georges Seurat, and Vincent van Gogh. In the early 20th century, Mondriaan's style became more abstract as he incorporated Cubist principles and limited his palette to primary colors separated by black lines, founding the De Stijl art movement. He is recognized as one of the pioneers of pure abstraction in painting.
