Ivan Fyodorov, Russian printer

Ivan Fyodorov or Ivan Fеdorov sometimes transliterated as Fiodorov, was one of the fathers of Eastern Slavonic printing. He was also a skilled cannon maker and the inventor of a multibarreled mortar. Fyodorov was forced out of Moscow because of his attempts to employ the “blasphemous” new printing techniques, and found refuge in Poland–Lithuania, first in Zabłudów, then most notably in Ostroh, where he was instrumental in the publication of the Ostrog Bible.
