Named in memory of Albrecht Kahrstedt (1897–1971), on the staff of the Astronomisches Rechen-Institut since 1922 and later in charge of the section at Potsdam. When that section combined with the Babelsberg Observatory, he became director. He was an indefatigable computer of minor planet orbits, notably of (1221) Amor, and he also prepared the right-ascension system of the FK3. (M 3930) _ _.
