The Boltzmann Medal (or Boltzmann Award) is the most important prize awarded to physicists that obtain new results concerning statistical mechanics; it is named after the celebrated physicist Ludwig Boltzmann. The Boltzmann Medal is awarded once every three years by the Commission on Statistical Physics of the International Union of Pure and Applied Physics, during a plenary conference concerning statistical physics.
The award consists of a gilded medal; its front carries the inscription Ludwig Boltzmann, 1844--1906.
All the winners are influential physicists or mathematicians whose contribution to statistical physics have been relevant in the past decades.
