DJORDJE NIKOLIC was born in Belgrade, Serbia, coincidentally on National Aviation Day. Since early childhood he has been fascinated by all aviation-related matters, always staring up in the sky and regularly visiting aviation themed museums across Europe. His interests are primarily in the Royal Yugoslav Air Force and the history of Belgrade in the period between the two world wars and his collection includes hundreds of original photographs, documents, pilot logbooks and other memorabilia. Djordje graduated in mechanical engineering from the University of Applied Sciences in Aachen, Germany. Having completed his studies in the German language, he was able to research and interpret historical documents relating to the German aircraft in Yugoslav service in the interwar and Second World War period. He is also an avid aircraft modeler and regularly attends local and national shows and contests. Djordje currently resides in Washington State, USA.
