Borngen and L. D. Schmadel at Tautenburg. Austrian physicist Ludwig Boltzmann (1844-1906) confirmed Maxwellian electrodynamics experimentally in 1872 and is one of the founders of the kinetic theory of gases. He explained thermodynamics in terms of statistical mechanics and black-body radiation. The name was suggested by the first discoverer.
