For 25 years after the war, Maas worked tirelessly as a reconciler. The new state of Israel, aware of what Maas had done for Jewish Germans, invited him for a state visit, making him the first non-Jewish German to visit the Jewish state, and in 1967, he was recognized by Yad Vashem as a Righteous Gentile. He became an unofficial ambassador between West Germany and Israel, persuading the German government to support Israel with money, technology, and diplomatic support. Maas published three books about his visits to Israel, and made countless speeches in churches and synagogues, explaining Israel to the Germans, and the new West Germany to Israelis. Hermann Maas died in his sleep in the night of September 26-27, 1970 while visiting relatives in Mainz. His body lies in the Handschuhsheim Cemetery in Heidelberg.
