52308 Hanspeterröser           Discovered 1991 Oct. 7 by L. D. Schmadel and F. Börngen at Tautenburg.
Hans-Peter Röser (b. 1949), director of the Institute of Space Studies at the University of Stuttgart, participated significantly in the observation campaign of the Kuiper Airborne Observatory and has been one of the key initiators of the subsequent US-German Stratospheric Observatory for Infrared Astronomy.
