About Yehoshua Neuwirth
Yehoshua Yeshaya Neuwirth (Hebrew: יהושע ישעיה נויברט; 15 February 1927 – 11 June 2013) was an eminent Orthodox Jewish rabbi and posek (halakhic authority) 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. == Biography == Rabbi Neuwirth was born in Berlin, Germany. His father Aharon served as rabbi in a number of German communities. After Kristallnacht, he travelled to Belgium on the Kindertransport (children's convoy) but was rejoined by his parents in 1939. They settled in Amsterdam, the Netherlands. During the Second World War, the family lived in hiding, supported by the Resistance. Two of his brothers were killed. During this time, Neuwirth had little access to rabbinic literature, apart from the volume of the popular work Mishnah Berurah that deals with the Shabbat laws. In 1946 he immigrated illegally to Palestine, and was detained at Atlit camp before being released and travelling to Jerusalem, where he was accepted at the Kol Torah yeshiva.
