2004 marks the 150th anniversary of the founding of the famous Breslau Seminary, where Leo Baeck and countless other German-Jewish theologians were trained for the Rabbinate. It also marks the 175th anniversaries of the Seminario Rabinico in Padua, Italy, and the Seminaire Rabbinique d'Alsace in France. It was in these seminaries that the so-called scientific study and knowledge of Judaism, or Wissenschaft des Judentums, developed as the modern approach to the comprehensive study of Judaism, including literature, music, language, art, and comparative philosophies. The scholarly and intellectual frame of reference created by these seminaries remains the model for contemporary Jewish studies. The influence of this scholarship penetrated Orthodox circles in Europe as well. This lecture will explore that influence and examine the nature of Wissenschaftlich influence in traditional 19th century Europe.
