Augustin-Jean Fresnel

Augustin-Jean Fresnel

1788 CE1827 CE · Broglie, Normandy

Augustin-Jean Fresnel was a French civil engineer and physicist whose work on interference, diffraction, and polarization established the wave theory of light on firm mathematical footing. He also designed the stepped Fresnel lens, which vastly improved lighthouse illumination. He is the optical physicist, distinct from his brother Fulgence Fresnel, the orientalist and Assyriologist.
