Isaac Nieto (1702–1774) (יצחק ניטו) was Ḥakham of the Portuguese congregation Sha'are Hashamayim, Bevis Marks, London, and the son of David Nieto. In 1749 Nieto became Gibraltar's first Rabbi when he travelled to Gibraltar from London and established the Shaar Hashamayim congregation. His 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 (London 1771) was the basis of all subsequent translations (e.g., those of Isaac Pinto and of Aaron and David de Sola).

Aharon Varady, founding director of the Open Siddur Project, is a copyright researcher and amateur book scanner. He prepares digital images and new digital editions of prayer books and related works in the Public Domain in order to make their constituent parts (prayers, translations, annotations, etc.) publicly accessible for collaborative transcription by project volunteers. (In some cases, he finds existing digital editions prepared by others that require correction and reformatting.) If you appreciate his efforts, please send him a kind note or contribute to his patreon account.
