(30837) Steinheil Main-belt Asteroid

Discovered on 15 January 1991 by F. Borngen at Tautenburg.

Carl August von Steinheil (1801-1870) was a professor in Munich, where he established an optical workshop in 1854. The workshop gained recognition through the efforts of his son Hugo Adolph (1832-1893) and grandson Rudolf (1865-1930), and the first wide-angle and aplanatic objective was constructed there.Naming citation (20020427/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
