About Yehoshua Neuwirth
Yehoshua Yeshaya Neuwirth was an eminent Orthodox Jewish rabbi and posek in Jerusalem. He was one of the primary students of Rabbi Shlomo Zalman Auerbach and the author of a two-volume Hebrew language treatise, Shemirat Shabbat Kehilchatah — translated into English as Shemirath Shabbath: A practical guide to the observance of Shabbath — a compendium of the laws of Shabbat which is viewed by many as an authoritative work regarding these laws. While Rabbi Auerbach issued most of his halachic rulings orally, Rabbi Neuwirth publicized many of his teacher's rulings on the laws of Shabbat in his book, first published in Hebrew in 1965. Feldheim Publishers published the first volume of the English-language translation in 1984; volumes 2-4 appeared in 1989, 1997, and 2001, respectively, and the current three-volume boxed set was issued in 2002.
