Physician; lived in Frankfort-on-the-Main in the seventeenth century. Though not in the employ of the community, his name is subscribed to the articles of agreement drawn up in 1656 between the congregation of Frankfort and its physicians, Solomon Bing and Abraham Hein. According to these articles, the Jewish physicians pledged themselves not to attend patients who were not members of the congregation without the permission of two elders of the synagogue. They also promised to visit the poor gratis; to respond to calls day and night; not to attend to any patient outside of the Jewish quarters; and not to accept the presidency of the congregation before the age of sixty.
