Burshtin is a Hasidic dynasty headed by Grand Rabbi David Eichenstein, the Burshteiner Rebbe. The main Burshteiner synagogue is located in Borough Park, Brooklyn.
The group originated in Burshtyn, now located in Ukraine, but was once part of Austria-Hungary. The Grand Rebbe is a scion of many great rabbinical dynasties, including Zidichov and Stretin. He has authored several books of Hasidic lore. He is a disciple of Grand Rabbi Joel Teitelbaum of Satmar. His brother, Grand Rabbi Isaac Menachem Eichenstein, is the Galanter Rebbe of Williamsburg, Brooklyn. His son, Rabbi Zeideleh has, in recent years, been functioning as a "Rebbe in Waiting" offering auxiliary and complementing Rebbe services alongside the Grand Rebbe. The second son, Rabbi Luzer, leads the local chapter in the Williamsburg section of Brooklyn.
The name 'Burshtin' is derived from Polish-Yiddish (bursztyn) or Ukrainian (Бурштин) for amber (German and Yiddish: Bernstein, Börnsteen „Brennstein“, lit. "burn[ing]stone"; lat. electrum or glaesum, Greek, Ancient (to 1453);: ἤλεκτρον ēlektron[1]).
The new Burshtin headquarters is built in its full glory and is located at 12th Ave and 56th Street in Brooklyn, New York. Burshtin opened a new synagogue in the Williamsburg section of Brooklyn serving the followers of Burshtin living in Williamsburg.
