Károly Zipernowsky (born as Carl Zipernowsky, 4 April 1853 in Vienna – 29 November 1942 in Budapest)[1] was an Austrian-born Hungarian electrical engineer. He invented the transformer with his colleagues (Miksa Déri and Ottó Bláthy) at the famous Hungarian manufacturing company Ganz Works and he contributed significantly with his works also to other AC technologies.
