Benedikt (Pinchas) Wolf was born in 1875. His father, Josef (Ze'ev) Wolf, founded the Talmud Thora in Cologne in 1861. Pinchas Wolf studied in Berlin and briefly taught at the Samson-Raphael-Hirsch school in Frankfurt am Main, before he became the director of the Talmud Thora in Cologne in 1900. Rabbi Pinchas Wolf (died 1950) has been described as a "goan in Torah wisdom and science, as well as a man of enterprise" (N.Z. Friedmann, Otzar Harabanim, p. 351, no 16988). He held this position until 1936, when he immigrated to Palestine. He died in 1968.
