Rabbi Yechezkel Landau was born in 1713 in Opatow, Poland, and received his Rabbinical education in Galicia. From 1746 he served as a Rabbi in Yampole on the upper Dniester, then was appointed Chief Rabbi of Prague and head of the Yeshiva (Talmudic school) in 1755.
He is best known to us today through his monumental work of she'alot uteshuvot entitled Noda Biyehudah, one of the most authoritative sources in Halacha. He was a devoted Rosh Yeshiva, a compassionate Rabbi, a strong community leader and a skillful negotiator with governments during the numerous wars and threatened expulsions that plagued the Jewish community.
The Nodah Biyehudah is buried in the Fibichova cemetery, near the television tower in Prague 3, at the metro station Jiriho Z Podebrad. The cemetery is open to the public on Sunday, Tuesday and Thursday from 11:00-16:00 and on Fridays from 10:00-14:00.
