29212 Zeeman           Discovered 1991 Sept. 10 by F. Borngen at Tautenburg.
Dutch physicist Pieter Zeeman (1865-1943) discovered the splitting of spectral lines in the magnetic field, allowing the analysis of the atomic fine structure. He also made a verification of special relativity. He shared the 1902 Nobel Prize for physics with his teacher Lorentz.
