Joseph Heinrich Beuys was a German artist, teacher, performance artist, and art theorist whose work reflected concepts of humanism, sociology, and, with Heinrich Böll, Johannes Stüttgen, Caroline Tisdall, Robert McDowell, and Enrico Wolleb, created the Free International University for Creativity & Interdisciplinary Research (FIU). He previously in his talks and performances also formed The Party for Animals and The Organisation for Direct Democracy. He was a member of a Dadaist art movement Fluxus and singularly inspirational in developing of Performance Art, called Kunst Aktionen, alongside Wiener Aktionismus that Allan Kaprow and Carolee Schneemann termed Art Happenings. Today, internationally, the largest performance art group is BBeyond in Belfast, led by Alastair MacLennan who knew Beuys and like many adapts Beuys's ethos.
