”Kosher Investigator beautifully captures Rabbi Berel Levy’s remarkable contributions to kosher food – and, more generally, to Judaism. A skilled investigator himself, author Dovid Zakilowski draws on oral interviews, obscure printed sources, and Rabbi Levy’s previously unknown personal papers to provide a revelatory account of his life. Written with great sympathy – and not shying away from controversial topics – this carefully researched book is a page-turner that readers will thoroughly enjoy.”

”Kosher Investigator pays honor to a founding father of modern industrial kosher certification. Rabbi Berel Levy’s passionate commitment to yiddishkeit and his keen powers of investigation helped transform the American kosher certification system into a model of reliable private regulation. Dovid Zaklikowski’s inspiring account also reveals the love of Torah and Am Yisroel that motivated Rabbi Levy’s many achievements.“
