Eliezer Waldenberg

Also known as The Tzitz Eliezer

1915 CE–2006 CE · Modern · Kfar Vitkin

R. Eliezer Yehuda Waldenberg (1915–2006), known as the Tzitz Eliezer after his magnum opus, was the defining voice of medical halacha for the modern era. Born in Jerusalem and educated in its yeshivot, he served as a dayan on the Rabbinate's Beit Din HaGadol for over forty years and was the long-time posek for Shaare Zedek Medical Center in Jerusalem.

His responsa on artificial insemination, IVF, organ transplantation, end-of-life care, abortion, autopsies, and countless other medical questions are the starting point for any modern halachic discussion of medicine. He was also a major posek on questions of conversion, the sanctity of the Land of Israel, and the halachic status of the State.
