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″).
Berlin Document Center
The Berlin Document Center (BDC) was created in Berlin, Germany, after the end of World War II. Its task was to centralize the collection of documents from the time of Nazism, which were needed for the preparation of the Nuremberg Trials against war criminals. The BDC was under American administration until 1994, when the German Federal Archives (Bundesarchiv) was allowed to take control of the BDC. While the paper records remained in Germany, the entire collection was microfilmed and made available at the National Archives in Washington, DC, where researchers have much better access unhindered by restrictive German privacy laws now in effect in Berlin.
