Yair Bacharach

Who was Yair Bacharach?

Yair Chayim Bacharach was a German rabbi and major 17th century posek, who lived first in Koblenz and then remainder of his life in Worms and Metz. His grandmother Eva Bacharach was a granddaughter of the Maharal of Prague, and his father Moses Samson Bacharach, and grandfather had served as rabbis of Metz.

He was the author of Havvot Yair a collection of responsa by the title of which is he commonly referred; its title is a reference to his grandmother Chava as well as to a place mentioned in Numbers 32:41 and elsewhere in the Jewish Bible. Other work includes his Mekor Chayim, which was intended as a principal commentary to Shulkhan Arukh but was withdrawn by Bacharach when he discovered that other commentaries, notably the Taz and the Magen Avraham, had appeared. It is still regarded a prime source of material concerning minhagim of the area and epoch.

Besides his Halakhic expertise he had complete mastery of all the sciences, music, history and wrote poetry. He compiled a 46 volume encyclopedia on many topics.

In 1689 the Worms community was decimated by the French during the Nine Years' War. Gradually, it was rebuilt. In 1699 he was appointed rabbi of Worms where his father and grandfather had served before him. He served for only three years until his death in 1702. The inscription on his tombstone begins with the words, “A great and dark horror befalls us from the hiding of the light of Rabbeinu...”
