Morris Louis lived from 1912 to 1962, a life that spanned two World Wars, a war on drugs, a war on love, a war on fruitcake, and a war on the abstract expressionists. Morris Louis painted in drips, thinning his paint and letting it run in rivulets down the canvas, pooling into a muddy brown on the drop cloth. It can have the effect of looking accidental. He is generally considered to be in the school of My Child Could Paint That.
