Karl Ziegler (1898-1973), born in Helsa, Germany, received his Ph.D. In 1920 from von Auwers at the University of Marburg. He became the director of the Max-Planck-Institut für Kohlenforschung at Mülheim/Ruhr in 1943. He shared the Nobel Prize in Chemistry in 1963 with Giulio Natta (1903-1979) for their work in polymer chemistry. The Ziegler-Natta catalyst is widely used in polymerization.
