In Germany, Best lived undisturbed for two decades. Only in the late 1960s did documents and witnesses turn up to shed light on his past in the Reich Main Security Office. But his trial was repeatedly postponed for health reasons. Best, an eternally colorful but sinister figure, died in June 1989.
Duckwitz remained in Copenhagen after the war, initially working as a representative of the West German chambers of commerce. He entered the diplomatic service when the Foreign Ministry was rebuilt in West Germany. He returned to Denmark as the West German ambassador in 1955. Ten years later, he chose to retire early, because he disagreed with Bonn's policy of marginalizing East Germany.
But soon Chancellor Willy Brandt brought him back and made him his chief negotiator for the Treaty of Warsaw, which was designed to reconcile Poles and Germans.
Soon after the end of the war, Denmark honored Duckwitz, the converted Nazi, for his role in the rescue campaign. In 1971, two years before his death, Yad Vashem, Israel's memorial to the Jewish victims of the Holocaust, presented him with its "Righteous Among the Nations" award.
