Yahrtzeit of Rabbi Chaim Yosef David Azulai (1724-1807), a great Sephardic sage known by the acronym "Chida." He was born in Jerusalem, and for many years served as a roving emissary for Jews in Israel, traveling to hundreds of Jewish communities throughout Europe and North Africa to raise money. Chida studied under the Ohr HaChaim, and wrote some 70 works of Jewish commentary and law, including the famous Birkei Yosef. He also served for a time as chief rabbi of Egypt. He died in Italy, and was later re-interred to his beloved Jerusalem.
