 The request from the KPD was rejected by the CDU, SPD and FDP.In the political climate of the Cold War, the Communist Party had little influence in Siegen, unlike in the neighboring district of Altenkirchen, where a convalescent home was named after Kraemer in 1948

With the ban on the KPD in the West in 1956 all efforts to rehabilitate Kraemer effectively ended.In 1975 the Jewish chairman of the Society for Christian-Jewish Cooperation Hugo Herrmann publicly referred to Kraemer, who, he said, had tried in Buchenwald, "put an end to the torture of the Jews", an effort for which he paid with his life.
