As a man of many discoveries, Karl Ziegler was also a man of many patents. As a result of his patent agreement with the Max Planck Institute, Ziegler was a wealthy man. With part of this wealth, he set up the Ziegler Fund with some 40 million deutsche marks to support the institute's research. Another namesake is the Karl-Ziegler-Schule, an urban high school that was founded on December 4, 1974, renaming a previously existing school. The school is located in Mülheim, Germany.
