The Henri Poincaré Prize 2000 was awarded to Joel Lebowitz for his
important contributions to various aspects of equilibrium and
nonequilibrium statistical physics: stability of matter, correlation
inequalities, phase transitions, and approach to equilibrium, to
mention just a few. In addition to this he has set his deep knowledge
of science and his tireless energy to the service of our community by
running the bi-annual statistical mechanics meetings and the Journal
of Statistical Physics. For many decades, Joel Lebowitz has been the
soul of statistical mechanics.
