2119 Schwall           Discovered 1930 Aug. 30 by M. Wolf and M. Ferrero at Heidelberg.

Named in memory of August Schwall (1877-1947), mechanician at the Heidelberg-Konigstuhl Observatory for almost half a century, night assistant to Wolf during 1914-1932, guiding exposures with the 0.72-m reflector. Name proposed by A. Bohrmann.
