Mordecai Paldiel born Markus Wajsfeld (March 10, 1937, Antwerp, Belgium) is a lecturer at Stern College (Yeshiva University) and Queens College in New York. He received a B.A. from Hebrew University and an M.A. and Ph.D. in Religion and Holocaust Studies from Temple University in Philadelphia. Paldiel is the former Director (1984-2007) of the Department of the Righteous Among the Nations at Yad Vashem in Jerusalem.

Paldiel was born into a Hassidic family of Szlomo Wajsfeld, a diamond trader originally from Miechów near Kraków and Hinde née Labin from Uhnow (now Ukraine) as one of their five children before World War II. Thanks to a Catholic Priest who was able to smuggle them across the border, the family fled from Nazi occupied Belgium via France to Switzerland in 1940 when he was 3 years old. Later after the war the family emigrated to New York.Mordecai Paldiel (1982), Secular Dualism: The 'religious' Nature of Hitler's Antisemitism, Temple University
