R. Isaac Zev b. Jacob Perez Wendrowsky (1854-1918) was born in Rozhanaka, Vilna Province. He studied in various yeshivot and was ordained by R. Isaac Elhanan Spektor of Kovno, R. Alexander Moses Lapidot of Raseiniai and R. Noah Hayyim of Szczucin. Unwilling to earn a living as a rabbi, he became a real estate agent. He immigrated to one of Baron Hirsch's agricultural colonies in Argentina in 1895 with the hope that the mild climate would be better for his asthma. While working the land he also contributed articles to the European Hebrew press. Due to friction with the administration of the colony, he immigrated to America in 1900. With many regrets, he became the rabbi of Hevrah Hayyei Adam Anshei Minsk (89 Henry St.) in order to support his family (p. 9). He later became a writer and an editor for the Yiddish press, to which he contributed hundreds of articles. R. Wendrowsky was a member of the Vaad Harabbonim of New York, a secretary of Agudath Harabbonim and a director of RlETS and Yeshivah Rabbi Jacob Joseph. He also organized the Agunah Society of Agudath Harabbonim to protect abandoned women. His brother was R. Aryeh Dov Wendrowsky.
