Bob Ross(October 29, 1942 - July 4, 1995) was a grandmaster American oil painter who primarily practiced the finer, more respectable arts of relaxation and kindness. His quiet, nurturing disposition was a form of therapy to the weary, and the reassuring intonations of his gentle voice hypnotized entire generations of would-be illustrators into creating a million-dollar art supply store enterprise.

Ross utilized the wet-on-wet oil painting technique, in which the painter continues adding paint on top of still wet paint rather than waiting a lengthy amount of time to allow each layer of paint to dry. Combining this method with the use of two inch and other types of brushes as well as painting knives allowed Ross to paint trees, water, clouds and mountains in a matter of seconds. Each painting would start with simple strokes that appeared to be nothing more than colored smudges. As he added more and more strokes, the blotches transformed into intricate landscapes.
