R. Dov Ber b. Abraham Menahem Abramowitz (1860-1926) was born in Vabalninkas (or Novolnick?), Lithuania, moved with his family to Jerusalem at the age of ten. Educated in his youth by R. Moses Nehemiah Kahana and R. Eleazar Dan Ralbag at the Etz Hayyim yeshivah, he was later ordained by R. Samuel Salant and he served as a district rabbi in Jerusalem. He immigrated to Philadelphia in 1894 and moved to New York two years later to become the rabbi of Mishkan Israel Anshei Suwalk. R. Abramowitz also had a Hebrew printing shop, Zion Printing. R. Dov Ber succeeded the recently deceased R. Shalom [Solomon] Elhanan Halevi Jaffe as the chief dayyan of St. Louis in 1906 and became "one of St. Louis's best known Orthodox rabbis" (USJ). R. Abramowitz endeavored to strengthen American Orthodoxy and helped found RIETS and the Agudath Harabonim. He was active in Zionist affairs and his support for the Va'ad ha-Kollel in Jerusalem was much appreciated by its leaders. He formed the first branch of Mizrahi in America in St. Louis, thus establishing the city as the center of religious Zionism in the country. He later served as the president of American Mizrahi. In 1918 he partook in the first meeting of the American Jewish Congress and he attended the London Zionist Conference in 1920. The following year he moved back to Jerusalem where he passed on and was buried on the Mount of Olives. His grandson was Abram Leon Sachar. R. Abramowitz wrote Dat Yisroel (New York 1899-1905) a multi-volume work on halakha and religious observance; Ktav ha-Dat (New York 1900) homilies; Sefer Ketubah ((New York 1901) on weddings; Beit Va'ad la-Hakhamim (New York 1903) the first rabbinic journal published in America; and several other works.
