He was educated at the Budapest University of Jewish Studies and at the University of Budapest (Ph.D. 1888). Immediately after his graduation he was called to the rabbinate of Carlsbad. Through his efforts the Kaiser Franz Josef Regierungs-Jubiläum Hospiz was erected at Carlsbad, at a cost of 500,000 Austrian crowns, to provide food, shelter, and medical treatment for indigent Jews who come to that city in large numbers in search of health. This institution was opened on 1 May 1903.
