Emília Rotter started out as a pair skater with Gyula Szabó, but when she paired up with László Szollás, they became the first great Hungarian figure skating pair. They placed second at the 1930 and 1931 European Championships, before winning their first World Championships in 1931 in Berlin. In a close contest with the Brunets of France, they failed to take the gold at the 1932 Olympic and World Championships, placing third and second respectively. They then won three World Championships in a row (1933-1935) and the 1934 European crown, but again failed to win at the Olympics, this time losing out to the home favourites Herber and Baier. The sixfold Hungarian champions retired after that season. Rotter later worked as an administrator at the University of Technology in Budapest.
