R. Shmuel HaLevi Wosner (1913-2015), author of Shevet HaLevi, was a leading halachic authority of the past generation. Born in Vienna, he was a disciple of R. Shmuel David Ungar, rabbi of Nitra, R. Yosef Elimelech Kahana, rabbi of Ungvar (both perished in the Holocaust) and later a close disciple of Rabbi Meir Shapiro at the Chachmei Lublin yeshiva. In 1939, he immigrated to Eretz Israel with his wife. He first settled in Jerusalem, where he studied under the leading rabbis of the city. He soon thereafter gained prominence as a leading Torah scholar and was appointed as rabbi and posek of the Geulah neighborhood. In 1947, he moved to Bnei Brak to serve as rabbi of the Zichron Meir neighborhood. He was recommended for this position by the Chazon Ish who already then discerned the greatness and strength of the young man and foresaw his illustrious future. After a short while, he was appointed rabbi of the Chug Chatam Sofer communities in the city and with time became renowned as a foremost halachic authority acknowledged by all circles. He responded to thousands of halachic queries which were published in the eleven volumes of his book Responsa Shevet HaLevi.
