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″).
Gottfried Kirch
Then in 1700 he was appointed the first astronomer of the Royal Society of Sciences (″Kurfürstlich-Brandenburgische Societät der Wissenschaften″) in Berlin on 10 May by Prince-elector Friedrich III. of Brandenburg (since 1701: King Friedrich I. of Prussia). The founding of the associated Berlin Observatory was a reaction to the new national observatories in Greenwich, Paris and St. Petersburg. To finance the Academy, the Prince-Elector conferred the "Kalenderpatent" on it (a monopoly on publishing almanacs). Kirch and his wife therefore were obliged to also finance the Academy by their almanac calculations.
