11309 Malus           Discovered 1993 Aug. 15 by E. W. Elst at Caussols.
Étienne-Louis Malus (1775-1812) was a French physicist who discovered the polarization of reflected light. In 1798 he accompanied Napoleon to Egypt as a member of the corps of engineers. In 1809 he published a paper on the discovery of the polarization of light.
