30837 Steinheil           Discovered 1991 Jan. 15 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.
