Who was Augustin Jean Fresnel?

Augustin Jean Fresnel was a French physicist who lived from 1788 to 1827. He studied light and optics. Fresnel's brilliant work led him to work on lighthouses and other technical areas that needed strong, focused lights. He was famous enough to have a street named after him in Metz, France.

The basic design for the Fresnel lens is still in use today, from lighthouses to stage spotlights to the solar panels on spacecrafts.
