Hayyim Tyrer

Hayyim ben Solomon Tyrer was an important Hasidic rabbi and kabbalist, and is today remembered for several well known Hasidic works.
He is also known as "Hayyim of Czernowitz", after his time there.
He was a pupil of Rabbi Yechiel Michl, as well as of the Maggid of Mezritch; both in turn direct pupils of the Baal Shem Tov. After he had been rabbi at five different towns, among them Mogilev, Czernowitz and Botoșani, he settled in Jerusalem. In 1812, he founded the Great Synagogue on Asiiskaya Street on the right bank of the river Byk. He died in Jerusalem in 1813, and was buried in a cave in the Jewish cemetery of Safed.
He was the author of: Sidduro shel Shabbat, kabbalistic homilies on Shabbat-related subjects Be'er Mayim Ḥayyim, novellæ on the Pentateuch, in two parts Sha'ar ha-Tefillah, kabbalistic reflections on prayer Ereẓ ha-Ḥayyim, in two parts: a homiletic commentary on the Prophets and Hagiographa, and novellæ on the tractate Berakhot
He is mentioned by Rabbi Sender Margalioth in his responsa on Shulchan Aruch, Even Ha'ezer.
Streets named after him are "Beer Maim Hayyim" in Rehovot and in Ramat Elchanan neighborhood in Bnei Brak, as well as "Ma'ale Beer Maim Haim" street in the Beit Vagan neighborhood in Jerusalem
