10656 Albrecht           Discovered 1971 Mar. 25 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
German astronomer Carl Theodor Albrecht (1843-1915) was influential in setting up the International Latitude Service. He became the first head of the ILS when it was established in 1899 at the Prussian Geodetic Institute, Potsdam.
