29208 Halorentz           Discovered 1991 Sept. 9 by F. Borngen and L. D. Schmadel at Tautenburg.
The Dutch physicist Hendrick Antoon Lorentz (1853-1928) formulated the classic electron theory and predicted the Zeeman effect. He derived the Lorentz transformation, the Lorentz contraction, time dilation and the velocity dependence of the mass. He shared the 1902 Nobel Prize for physics with his student Zeeman.
