Etienne-Louis Malus (1775-1812) the French officer, engineer, physicist and mathematician. He was particularly interested with the study of light, and he studied geometic systems called ray systems, closely related to Julius Plucker's line geometry. His discovery of the polarization of light by reflection was published in 1809, and his theory of double refraction of light in crystals, in 1810. He is remembered for Malus' Law which gives the resultant intensity, when a polariser is placed in the path of an incident beam. His names is one of the 72 inscribed on the Eiffel Tower.
