Letter of Approbation by Rabbi Shmuel HaLevi Wosner
Letter of approbation for a book (14 lines), handwritten and signed by R. Shmuel HaLevi Wosner, author of Shevet HaLevi. Bnei Brak, [ca. 1976-1977].
Approbation to the book Mekor HaBracha - laws of blessings, authored by R. Gavriel Krausz, head of the Manchester Beit Din. In his approbation, R. Wosner writes that the subject of the laws of blessings "is reputed to be a very complex topic, to distinguish between the certain and the doubtful, and these are matters of utmost importance… yet people treat it lightly, by devising various leniencies which have no halachic basis". Further in the letter, R. Wosner writes a beautiful aggadic thought pertaining to blessings.
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 R. 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 earned prominence as a foremost Torah scholar and was appointed 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.
