Étienne-Louis Malus

Biography

Étienne-Louis Malus (1775–1812) was a French military officer and physicist whose scientific contributions, though brief due to his early death, significantly advanced the understanding of light and optics. His discovery of the polarization of light through reflection established fundamental principles in physics that continue to inform optical science.

Malus's dual career in military service and scientific research exemplified the intellectual engagement of French officers of his era. He was laid to rest at Père Lachaise Cemetery in Paris, where he is remembered as a talented scientist whose promising career was cut short but whose discoveries endure.
