Robert Filliou (French, 1926-1987) was a French artist and economist associated with the Fluxus movement who produced works as a filmmaker, action poet, sculptor and director of artistic happenings. His practice emphasized the autonomy of the individual and was rooted in the life/art intersections that exist in Fluxus philosophy. Filliou was influential in the development of the Mail Art practice and is well known for his proclamation of Art’s Birthday, which continues to be celebrated to this day.
