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.
Telegrafenberg
In 1874 the first observatory was built on the hill. Over the years the site developed in a main center for astronomy, physics and geosciences. A number of institutions have their headquarters on the Telegraphenberg, among them the Potsdam Institute for Climate Impact Research and the GFZ German Research Centre for Geosciences, as part of the Albert Einstein Science Park that includes the hill.
