In 1897, Tatra produced the first motor car in central Europe, the Präsident automobile.  In 1921, it changed its name to "Kopřivnická vozovka a.s.", and in 1919 changed from the Nesselsdorfer marque to the "Tatra" badge, named after the nearby Tatra Mountains on the Polish-Czechoslovak border at the time (now this range is on the Polish-Slovak border).
