Haham of the Portuguese congregation Sha'are Shamaim, Bevis Marks, London; born 1702; died at London 1774; son of David Nieto. He was officially appointed as "ḥakam ha-shalem" in 1733, but gave up the post in 1741 and went abroad. He returned in 1747 and took up the profession of notary. In 1751 the congregation requested him to accept the post of ab bet din, his colleagues being Isaac de Valle and Jacob Coronel. A few years afterward a violent dispute arose with regard to the titles of the members of the bet din and as to the relation of the members to one another. Nieto wrote a letter of resignation March 17, 1757, and on July 14 following he was prohibited from exercising the functions of assessor.
Nieto preached on Feb. 6, 1756, the day of fast and penitence ordered by the king, a "Sermon Moral," published in Spanish and English in London, 1756. Better known is his translation of the prayer-book in two volumes: "Orden de las Oraciones de Ros Ashanah y Kipur" (London, 1740) and "Orden de las Oraciones Cotidianas, Ros Hodes Hanuca y Purim" (ib. 1771). This translation was the basis of all subsequent translations (e.g., those of Pinto and of A. and D. da Sola).
