Named in memory of Ulrich Haug (1929–1992), German astronomer, who investigated interplanetary dust particles in his early years in Tübingen and who is known from later work at the Hamburg Observatory, mainly for his contributions on interstellar extinction and for observations with the Schmidt telescope, moved from Hamburg-Bergedorf to the German-Spanish Astronomical Center at Calar Alto, where he made tests for quasars being the basis for the Hamburg Quasar Survey.
