10506 Rydberg          
Johannes Robert Rydberg (1854-1919) was a Swedish physicist educated at the University of Lund who held the chair of physics from 1901 to 1919. He is well-known for the Rydberg constant, which appears in a spectroscopic expression that relates the various lines in the spectra of chemical elements.
