Francis Bacon (28 October 1909 – 28 April 1992) was an Anglo-Irish figurative painter known for his bold, austere, graphic and emotionally raw imagery. Bacon's painterly but abstract figures typically appear isolated in glass or steel geometrical cages set against flat, nondescript backgrounds. He began painting during his early 20s; yet he worked only sporadically until his mid 30s. Before this time he earned his living as an interior decorator and designer of furniture and rugs....wikipedia

It amazes me that he could get such beautifully painted paintings to come out of his horribly unkempt studio.
