He was born at Ladány (Tiszaladány), Borsod-Abaúj-Zemplén County, Hungary. The descendant of an ancient family of scholars, he pursued his rabbinical studies at the yeshivot of Ujhely, Verbé, and Eisenstadt (the last-named then in charge of Israel Hildesheimer). He studied (1868–71) philosophy and Orientalia at the universities of Vienna, Budapest, and Berlin, taking his PhD. degree at Tübingen. In December 1871, he was called as rabbi to Lauenburg in Pomerania; in 1874, to Gnesen, Prussian Posen; and in September 1878, to Frankfurt. At Frankfurt he organized two model religious schools. Horovitz was a director of the Deutsche Rabbinerverband and president of the German Jewish orphanage at Jerusalem.
Conflict and career
Horovitz was rabbi in Frankfurt at a time when the disagreements between the Orthodox and Reform factions were reaching their peak. Horovitz was appointed to chair a committee on ritual to placate the Orthodox followers of Samson Raphael Hirsch, who were threatening to found of a separate community, the Israelitische Religionsgesellschaft ("Religious Society of Israelites"). He was given authority over the entire community's religious institution, and promoted the construction of a new Orthodox synagogue on the Börneplatz, which was dedicated on September 10, 1882. Horovitz promoted the coexistence between the different factions; maintaining that it was possible for a unified community to exist while both sides exercised autonomy over their own institutions.
Horovitz died in Frankfurt in 1910. He was buried in the cemetery in RatBeil Straße.
