Joseph Beuys

Joseph Beuys was a German-born artist active in Europe and the United States from the 1950s through the early 1980s, who came to be associated with that era's international, Conceptual art and Fluxus movements.
Beuys's diverse body of work ranges from traditional media of drawing, painting, and sculpture, to process-oriented, or time-based "action" art, the performance of which suggested how art may exercise a healing effect (on both the artist and the audience) when it takes up psychological, social, and/or political subjects.
Beuys is especially famous for works incorporating animal fat and felt, two common materials - one organic, the other fabricated, or industrial - that had profound personal meaning to the artist. They were also recurring motifs in works suggesting that art, common materials, and one's "everyday life" were ultimately inseparable.
