Rabbi Yonasan Steif

As av beit din of Budapest, Rabbi Yonasan Steif was a leading halachic authority in pre-war Hungary. A survivor of the Bergen-Belsen concentration camp, he later immigrated to the United States and served as a preeminent posek for the community of Hungarian expatriates in Williamsburg, Brooklyn. Although not a Hasid himself, he was highly respected in Satmar circles and served them as a halachic decisor. His extensive responsa, published as *She'eilos u'Teshuvos Mahari Steif*, are considered a classic of modern Hungarian halachic jurisprudence and are widely cited.
