Jozef Maximilián Petzval (born Jan. 6 1807 in Szepesbéla (Spišska Belá), former Hungarian Komitat Zips in Slovakia, died Sept. 19 1891 in Vienna) got his engineering diploma at the University of Pest in 1828. He spoke several languages. In 1832 he made a doctorate at the philosophical faculty after further studies in mathematics and physics. From 1837 to 1877 he was tenured professor for mathematics at the University of Vienna.
