Abstract
Professor Ilya Prigogine (January 25, 1917 -- May 28, 2003), Nobel Laureate 1977 in chemistry, was one of the great visionaries of our time. Not content to rest on his laurels, he continued hard technical scientific publication, often with junior colleagues, for 25 years after the Nobel Prize was awarded to him. His fields of work included non-equilibrium thermodynamics, the emergence of dissipative structures and complex behavior, and the foundations of the arrow of time in natural science. He directed two major research institutions: the Center for Studies in Statistical Mechanics and Complex Systems at the University of Texas at Austin and the International Solvay Institutes for Physics and Chemistry at Brussels.
