Piotr Zawadzki (died 1796), a type founder, printer, Warsaw bookseller, noble of the Ostoja coat of arms by origin. In 1777, having obtained royal privilege, he opened a "punchcutting studio for cutting out letters from steel and casting them" in Warsaw. The workshop produced Latin, Hebrew, Greek, and Cyrillic fonts as well as sheet music. It supplied at least thirty-two domestic printing houses from Połock to Kraków. In 1789, Zawadzki founded a printing house, which by the end of its activity had produced over two hundred prints, mainly books.
