Pierre Brassau
Peter, better known by his alias Pierre Brassau, was a chimpanzee and artist who was the subject of a 1964 hoax perpetrated by Åke "Dacke" Axelsson, a journalist at the Swedish tabloid Göteborgs-Tidningen. Axelsson came up with the idea of exhibiting a series of paintings made by a non-human primate, under the pretense that they were the work of a previously unknown French artist named "Pierre Brassau", to test whether critics could tell the difference between true avant-garde modern art and the work of a chimpanzee.
