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″).
Leuschner Observatory
In 1898, Armin Otto Leuschner was appointed the director of the Students' Observatory, a post that he held until his retirement in 1938. During this time, "the observatory became a center for the computation of the orbits of comets, minor planets, and satellites." Astronomer Simon Newcomb said that Leuschner organized the department and observatory into "a thorough school of astronomy, than which [...] there is none better." After he stepped down, the observatory was directed by a series of well regarded astronomers, including Otto Struve from 1950–59 and Louis G. Henyey from 1959–64. The Students' Observatory was renamed Leuschner Observatory by the Regents of the University of California in 1951 in honor of A. O. Leuschner. The Space Sciences Lab, which operates SETI, began operations in 1960 at Leuschner Observatory until a permanent home in the Berkeley hills was completed in 1966.
