10669 Herfordia           Discovered 1977 Mar. 16 by H.-E. Schuster at the European Southern Observatory.
Herford, a town in what is sometimes called "Eastern Westfalia", is known for its numerous light industries and beautiful surrounding countryside. It was in Herford that Walter Baade, born in nearby Schröttinghausen, first realized his love of astronomy.
