Harav Shmuel Wosner was born in 1913 in Vienna, Austro-Hungary and studied in the Yeshivas Chachmei Lublin of Poland led by Rabbi Meir Shapiro.
He was also a student of Rabbi Shimon of Zelicov who was the official supervisor at the Yeshiva. In Vienna, he had known and befriended the Rabbi Chanoch Dov Padwa of Galicia.
He married and immigrated to Palestine before the Holocaust and dwelled in Yerushalayim where he studied at the Dushinsky Yeshiva. It was in that time that, in spite of his young age,
he became a member of the Edah HaChareidis. When he relocated to Bnei Brak, upon the incentive of the Chazon Ish, Rabbi Dov Berish Widenfeld of Tshebin, Rabbi Isser Zalman Meltzer
and Rabbi Yitzhak HaLevi Herzog he established his "Yeshiva Chachmei Lublin" bearing the same name as the one in Lublin where he studied in his youth. He is the author of several works
of Jewish law, such as Shevet HaLevi ("The Tribe of Levi"), a comprehensive series of Halachic rulings and responsa on Jewish laws comprising ten volumes and several other Torah books
all bearing the same name. [Source]
