Joseph Beuys (1921-1986) was a German artist, teacher, and art theorist who is regarded as one of the most influential artists of the second half of the 20th century. Beuys’ work is grounded in the transformative and the guided principle of art’s ability to heal through its psychological, social, and/or political subject matter. Core, also is the concept that art, common materials, and one's "everyday life" are ultimately inseparable.
