Yosef Chaim Sonnenfeld

Yosef Chaim Sonnenfeld, also spelled Zonnenfeld (1 December 1848 – 26 February 1932), was the rabbi and co-founder of the Edah HaChareidis, a Haredi Jewish community in Jerusalem, during the years of the British Mandate of Palestine.

His father, Rabbi Avraham Shlomo Zonnenfeld, died when Chaim was five years old.

Sonnenfeld and Abraham Isaac Kook were vigorous opponents in many areas.

However, notwithstanding their disagreements, the two rabbis enjoyed a relationship of mutual respect and friendship.

[1] Sonnenfeld wrote scholarly commentaries on the Torah, Talmud, and Shulchan Aruch.
