FRIEDENSREICH HUNDERTWASSER (1928-2000) WAS an artist, architect, and activist known for his holistic, all-encompassing embrace of nature and ecology in both his life and work. While on the surface his artistic and personal style would seem to place him squarely in the freewheeling hippie milieu of the late 60s, he also possessed a rigorousness and discipline that made him more monk than hedonist.
