1810 CE–1874 CE · Modern · Frankfurt am Main
Abraham Geiger (1810–1874) was a German Jewish scholar and theologian who fundamentally shaped the intellectual foundations of Reform Judaism. Born in Frankfurt, he studied at the University of Bonn and became a rabbi in Wiesbaden and later Breslau before settling in Berlin. Geiger pioneered the Wissenschaft des Judentums ('science of Judaism'), applying rigorous historical and philological methods to Jewish texts and traditions. He argued that Judaism possessed an essential ethical monotheism that could develop and adapt while maintaining continuity with its past. Through his scholarship, polemics, and rabbinic leadership, he demonstrated that Jewish practice and belief could be modernized without abandoning Jewish identity, profoundly influencing the theological and institutional direction of Reform Judaism throughout the nineteenth century.

Frankfurt am Main, on the Main river in Hesse, Germany, became an imperial city in 1372. Holy Roman kings were elected here, by law from 1356, and from 1562 to 1792 they were also crowned here, and in 1848 the first elected German parliament met in its St. Paul's Church. Philipp Jakob Spener, the city's Lutheran chief pastor from about 1666 to 1686, is regarded as the father of Pietism. From 1462 its Jews were confined to the Judengasse, early modern Germany's largest Jewish community. The Chatam Sofer was born here in 1762, and Samson Raphael Hirsch led its Orthodox Israelitische Religionsgesellschaft from 1851 until his death in 1888. Most of its Jews fled or were killed in the Holocaust.
