(10838) Lebon Main-belt Asteroid
Discovered on 9 March 1994 by E. W. Elst at Caussols.
Gustave Le Bon (1841-1931) was a French social psychologist who became famous through his book La psychologie des foules (1895): “Crowd behavior is unanimous, emotional and intellectually weak”. Freud's Massa und Ich-analyse (1920) owes much to his ideas.Naming citation (20000523/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
