Berlin Observatory
The Berlin Observatory (Berliner Sternwarte) is a German astronomical institution with a series of observatories and related organizations in and around the city of Berlin in Germany, starting from the 18th century. It has its origins in 1700 when Gottfried Leibniz initiated the "Brandenburg Society of Science″ ("Sozietät der Wissenschaften") which would later (1744) become the Prussian Academy of Sciences ("Preußische Akademie der Wissenschaften"). The Society had no observatory but nevertheless an astronomer, Gottfried Kirch, who observed from a private observatory in Berlin. A first small observatory was furnished in 1711, financing itself by calendrical computations.

Nedeljković was appointed first director of the newly founded Observatory. On 1 July 1887 Nedeljković started his activity at the provisory astronomical and meteorological observatory which was located in the rented house of the Gajzler family at 66 "Svetozara Markovića" Street. Located at the crossroads of the "Vojvode Milenka" and "Svetozara Markovića" streets in the historical neighborhood of Vračar (though today administratively in the municipality of Savski Venac), the house still stands today. Adopting the justified request of Prof. Nedeljković, a new Minister of Education, Dr Vladan Đorđević passed on 27 September 1888 the Regulation on the establishment of unified network of meteorological stations in the whole country. Then Observatory become Central meteorological station for data collection.
