The influential Beuys helped realign the parameters for art-making. He met Lorenz through working with the wildlife film-maker Sielmann in post-war years. Grass was a fellow-student, though their connection was tangential. Paik and Maciunas were met in the early 60’s, the start of his association with Fluxus. He made sound pieces with Paik, Moorman and Vostell, cooked at Spoerri’s restaurant, invited Morris and Rainer to perform, met Warhol in Naples, and greatly respected Cage. Richter ran into him as a student, Kiefer was among those he taught. Sacked from his teaching job, he founded a Free University with Böll.
