set up its documentary collection. He immigrated to the United States of America in 1948 at the invitation of Salo Baron. There he first held the post of research fellow and then, from 1951 until his death, that of lecturer at Columbia University. From 1949, he also headed the Jewish Teachers Seminary and taught courses at the Herzliya Teachers Seminary in Israel and was the Research Director of the YIVO-Yad Vashem Joint Documentary Project, a bibliographical series on the Holocaust, from 1954-1960. Friedman's post-war research focused on the Holocaust, including an account of the Warsaw ghetto uprising titled Martyrs and Fighters: The Epic of the Warsaw Ghetto (1954) and a volume describing Christian rescue, Their Brothers' Keepers (1957). A volume of his essays devoted to Holocaust topics, Pathways to Extinction: Essays on the Holocaust (1980), was edited posthumously by his wife, Dr. Ada Eber-Friedman. He also remained committed to his earlier scholarly interests, and published articles in Yiddish, Polish, Hebrew, French, and English, such as "Polish Jewish Historiography between the Two Wars" and "The First Millennium of Jewish Settlement in the Ukraine and in the Adjacent Areas."
