Branko Mladenović, 14th century Serbian feudal lord, founder of the House of Branković.
With schoolmate Gagi Mihajlović, Mladenović formed a band called Limunovo drvo (Lemon Tree) that dabbled in melodic hard rock.
In his spare time, Mladenović prepared and published a series on Eastern Europe, as well as early articles on the Serbs in Canada for the Canadian Encyclopedia, book reviews for The Montreal Star, and a study of East European Law in Canada for Bulletin zur Ostforschung.

In 1969, his students presented Professor Mladenović with a Festschrift to commemorate his 65th birthday.
In 2002, the band participated the Milan Mladenović tribute album Kao da je bilo nekad... Posvećeno Milanu Mladenoviću (As if It Had Happened Sometime... (Dedicated to Milan Mladenović)) with the cover version of the track "O, O, O...", originally released on the Šarlo Akrobata album Bistriji ili tuplji čovek biva kad... (Brighter or Dumber a Man Becomes When...).
