About the name	Named in 1847 by Johann Friedrich Ludwig Hausmann in honour of the French physicist, mathematician, meteoriticist, astronomer, and mineralogist, Jean-Baptiste Biot [April 21, 1774, Paris, France - February 3, 1862, Paris, France], who studied the optical properties of the micas. Biot and his associate, Félix Savart, discovered that an electric current in a wire produced a magnetic field. Biot received many awards in his lifetime in recognition of the value of his scientific researches.
