What was Claude Monet painting style?

Claude Monet is a hero of the painting movement referred to as Impressionism. Impressionism is a painting style that developed in France in the 19th century as a radical departure from rigid academic representational panting. These painters were interested in the way light defines the way we see. They used small dabs of vibrant colors (many of which had only recently become available due to the industrial revolution) to create their pictures. They were also champions of leaving the studio to paint outside (plein air painting) taking with them small canvases and tube paints (another modern novelty).

While it would be impossible to choose a single image or subject that Monet is known for, in the art world the phrase "Water Lilies" is synonymous with him.
