Geiger
Geiger, Abraham, the son of a rabbi, was "born at Frankfort-on-the-Maine in 1810, and trained for his father's profession, following also the courses at Heidelberg and Bonn. He showed much ability, and wrote as a student valuable essays on the relations between Judaism and Mohammedanism. In 1832 he became Rabbi at Wiesbaden, and in 1838 was transferred to Breslau, where he' spent twenty-five years of learned industry, producing his Textbook on the Mischna, Studies from Maimonides, and a treatise of high interest on the text and translation of the Bible as influencing the development of Judaism. His views brought him into conflict with old-fashioned theologians. He was, however, made Rabbi at Frankfort in 1863, and thence chosen to the Chief Rabbinate of Berlin in 1870, dying there in 1874. Among his later works are Pliarisees- and Saddueees, A History of Judaism, and a Jewish prayer-book. His ephemeral publications on Semitic philology and historical and literary subjects ' were very numerous.
