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.

Alexander Alexander (also, Alexander ben Judah Leib, Hebrew: אלכסנדר בר יהודה לײב; d. ca. 1807), from London, was a translator of many of the first Jewish prayerbooks in the English language, for both (S&P) Sefaradim and Ashkenazim. He initially used the press of a non-Jewish printer, J. & W. Richardson, before acquiring his own, the first Jewish press in London. Prior to translating the S&P liturgy Alexander produced an Ashkenazi prayer book translated into English in collaboration with B. Meyers. Both were printed in London in 1770 by W. Tooke. In the same year he also printed two Haggadot, one for Sefaradim and another for Ashkenazim printed by W. Gilbert. Alexander worked for the printer Moses Hertz Hague from 1770 to 1773, and his name is recorded as a typesetter for the second volume of מלך הדרת, a commentary on the Zohar by Rabbi Shalom Buzaglo.
