Dr.-Heinrich-Maier-Staße

The priest Heinrich Maier was a member of the resistance group Maier-Messner-Caldonazzi during the NS regime. Maier served as a priest in the Vienna parish of Gersthof. His acquaintance Franz Josef Messner was the general director of the Semperit AG. Another member of the group was Walter Caldonazzi, who worked at the United Forests in Vienna. The group produced and distributed anti-Nazi leaflets. In addition, they supplied British and American intelligence agencies with information about the German arms industry. In the spring of 1944, the group was uncovered by the Gestapo. Heinrich Maier was brought before the People's Court together with nine other accused and sentenced to death. After a period of imprisonment in the Mauthausen concentration camp, the NS judiciary executed him at the Vienna District Court on 22 March 1945.
