Rabbi Yitzchak Reuben Nehmad was born in Buenos Aires on March 17th, 1952, into a family whose rabbinic and rabbinical-slaughter tradition spans generations. His father, Rabbi Eliahu Chay Nehmad, was a renowned Shochet in Buenos Aires — son of Rabbi Yitzchak Nehmad, who came from Aram Tzoba (Halab) and was among the first Shochatim of the city.
Rabbi Nehmad began his Torah studies at Talmud Torah Chazon Ovadia, part of the Shuva Israel community — at the time, one of the leading Charedi communities of Buenos Aires. He continued his Yeshiva Ketana studies in the same institution, completing this stage of his education at the Satmar Yeshiva in New York.
At eighteen, Rabbi Nehmad traveled to Eretz Israel to pursue Yeshiva Gedola studies. He was admitted to the prestigious Yeshivat Porat Yosef under the tutelage of Rabbi Shalom Cohen ztz"l, where he remained for nearly four years (1970–1974). Beyond his mastery of Gemara, he received Semicha as Shochet and Bodek from Rabbi Nissim Azran.
After returning to Buenos Aires and marrying, Rabbi Nehmad settled with his family in Bnei Brak. There he studied at Kollel Chazon Ish and received Semicha in Issur veHeter from Rabbi Nissim Karelitz ztz"l and Rabbi Shmuel haLevi Wosner ztz"l. He also became a recognized Mohel in the city of Buenos Aires.
For almost fifty years, Rabbi Nehmad has worked in the field of Shechita. For many years he served as Shochet; today he holds the position of Bodek. He has worked for the Rabbanut HaRashit of Israel and was responsible for the export Shechita of Neve Tzion, the certification authority directed by Rabbi Shalom Cohen ztz"l.
Today, in Buenos Aires, Rabbi Nehmad leads a Shechita team whose production serves both the local market and export — with the United States as one of its principal destinations. His dedicated work in Shechita has never interrupted his Torah scholarship: Rabbi Nehmad serves as Rosh Kollel at Kollel Horaa Beer Yitzchak, based at Beit Haknesset Chevre Mishnayot. He is recognized within the Argentine community as a Talmid Chacham, and is the author of Toledot Yitzchak, a published book on the Halachot of Hafrashat Challah.
