Mordechai Ben Šemuel Maisel was a businessman, philanthropist, Jewish community head, and builder of Prague’s Jewish town during the late 16th and early 17th centuries. He established a successful banking business and several silver and gold mines in Bohemia. Maisel’s financial success was instrumental to the tactical success of the Holy Roman Emperor’s forces during the Turkish Wars, which allowed him more financial freedoms and decisions that made him wealthier.
