Đorđe Stanojević was also the member of the pleiad of great man that led Serbia on the road to progress. Physicist, astronomer and meteorologist per education, after studies abroad comes back to Serbia in 1887. In many aspects of his work, he was a pioneer: he was the first Serbian astrophysicist and author of first works in this field, he realized the first radio broadcasting in Serbia, realized the first X-Ray in Serbia, and wrote the first book about aeronautics. He was also a great promoter of science and rector of Belgrade University (1913-1921). Apart from that, he was engaged in the inclusion of Serbia in the system of international standards and the implementation of the metric system.
In spite of that, Djordje Stanojević remained remembered as a man who had decisive influence on the start of electricity use in Serbia. As a matter of fact, five years after the building of the hydroelectric power plant at the Niagara Falls, Stanojević, in Užice, performs the construction of the hydroelectric power plant according to the Tesla system. After that, power plants are erected in Vučje, Niš, Veliko Gradište, Ivanjica, Vlasotince, enabling electrification and industrialization of Serbia. Thanks to his efforts, Belgrade obtains the electrical lightening in 1893, and the next year also the electrical tram. Thanks to personal friendship, he managed to bring Nikola Tesla in his only visit to Serbia on June 1, 1892, and two years later, he publishes a book “Nikola Tesla and his Inventions”.
Great love of Đorđe Stanojević was photography. He is the author of the first Serbian photography in colour, and he arranged the first Serbian photo-monography in Serbia. Dealing with photography encouraged him to create his only known invention, protected by patents in Belgium, France and Great Britain (GB 191313077 A), album for keeping photographic plates – negatives.
