Canaris also intervened to save a number of victims from Nazi persecution, including Jews, by getting them out of harm's way; he was instrumental, for example, in getting five hundred Dutch Jews to safety in May 1941. Many such people were given token training as "Abwehr" "agents" and then issued papers allowing them to leave Germany. One notable person he is said to have assisted was the then Lubavitcher Rebbe in Warsaw, Rabbi Yosef Yitzchok Schneersohn. This has led Chabad Lubavitch to campaign for his recognition as a Righteous Gentile by the Yad Vashem Holocaust memorial.
