German, 1921-1986. Joseph Beuys was an avant-garde sculptor and performance artist recognized for his controversial works created in a ritualistic manner with unconventional materials. Beuys shared strong credence with Fluxus; a democratic form of creative attitude open to adoption by the artist from various media and eras. Critics found an influence of German Expressionism in his work owing to its obsessive and unsettling qualities and the constant attempt to transform and reshape human conditioning and social structures. In one of his performances, he locked himself in a room for three days, with a live coyote and armed only with some felt and a cane.
