Bravais, Auguste 

Born Aug. 28, 1811, in Annonay; died Mar. 30, 1863, in Versailles. French crystallographer. Member of the Paris Academy of Sciences (1854) and professor at a poly technical school in Paris.

Bravais founded the geometric theory of the structure of crystals. He discovered the fundamental forms of spatial lattices, known as Bravais lattices, and advanced the hypothesis that they are constructed from points uniformly distributed in space.
