Berlin Observatory
The construction of the new Berlin Observatory proceeded from a cabinet order of 10 November 1830 according to the design of Schinkel. An approximately one hectare plot was acquired at a price of 15,000 Thalers in the present-day area of Berlin-Kreuzberg. The foundation stone was laid on 22 October 1832 and the observatory was ready by 1835, on the area currently bounded by the streets ″Friedrichstraße″, ″Besselstraße″ and ″Lindenstraße″. The southern end of the ″Charlottenstraße″ was later named ″Enckeplatz″ in honor of the director at that time and the observatory acquired the address of Enckeplatz 3 A (now: ″Enckestraße 11″).
German Academy of Sciences at Berlin
The academy was founded in 1946 by the Soviet Military Administration in Germany to continue the long tradition of the Prussian Academy of Sciences and the Brandenburg Society of Sciences, which had been founded in 1700 by Gottfried Wilhelm Leibniz. To facilitate publishing, the Akademie Verlag was founded also in 1946. The 250th anniversary in 1950 was already boycotted by West Germans due to the influence of the socialist East German authorities, which mainly had East Germans elected to the academy in the decades to follow. It became the most important academy in the German Democratic Republic, and was accordingly renamed 'Academy of Sciences of the GDR' (Akademie der Wissenschaften der DDR) in 1972, once the division of Germany was accepted as the state of affairs. In the 1980s, the AdW itself had over 200 members, including two dozen West Germans. It coordinated research at 59 institutes that employed 22,000 persons. Following the fall of the Berlin wall, academy members called for a reform of the academy, rejecting the leading role of the Socialist Unity Party of Germany.
