Michael Gottschalk was a local bookbinder and bookdealer who took over the management of Johann Christoph Beckman's printing press in Frankfort d.O. in 1693. Gottschalk became the moving spirit of the press for almost four decades. His most ambitious project was a completed edition of the Talmud, printed in 1697-1699, a work for which the Frankfurt press is best known to this day.
