Don Leo Jonathan
In the early 1970s he created the Catch Wrestling Association (CWA) based in Austria but promoting shows in the surrounding countries as well. On August 2, 1977 Wanz defeated Jan Wilkens on a show in Cape Town, South Africa to become the first holder of the CWA World Heavyweight Championship, bringing the championship back to Europe once the tour was over. Over the next two years Wanz defended the championship in Austria and Germany on several occasions, before losing to Don Leo Jonathan on September 1 in Johannesburg, South Africa. Wanz brought Jonathan to Graz, Austria to win the championship for a second time in front of a home town crowd. In Germany, he wrestled Andre the Giant and was one of the few wrestlers to bodyslam him.
