Jacob Sadé (Hebrew: יעקב שדה) (3 June 1925 – 16 March 2020) was a German-born Israeli otolaryngologist, also an emeritus professor at the Sackler School of Medicine, Tel Aviv University.
He established the local League for Hearing Improvement and was one of the editors of the Acta Otolaryngologica Orientalia—an International ear, nose and throat journal.
In 1967 he joined the Weizmann Institute of Science as a visiting professor, working for four years in the Polymer Department, headed by Prof. Aharon Katzir, where he carried out research in the field of Otology.
In 198, Sadé was appointed Incumbent of the Felix and Sara Dumont Chair of Hearing Disorders Research at Tel Aviv University.
From 1986 to 1990 Sadé served as President of the Israeli Ear Nose and Throat Society and was the coordinator of the ENT yearly scientific prize.
Sadé was the first to describe the mucus-ciliary system of the middle ear—studies which demonstrated that the function of these microscopic organelles depends on the presence of mucus and its biochemical composition.
