Joshua Solomon Soncino

Printer of the first-ever printed Talmud tractate — Berakhot, 1483/84 — and, per Marvin J. Heller's primary scholarship, the actual originator of the Gemara-center/Rashi-inner-margin/Tosafot-outer-margin page layout that every subsequent Talmud edition has followed "with rare exceptions." Matters to this vault because he is the correction the vault's earlier Bomberg framing needed: the layout is his, not Bomberg's; Bomberg's later, far more famous editio princeps used Soncino's layout and is independently credited only with fixing the standard pagination.
