Ilya Prigogine (Russian: Илья́ Рома́нович Приго́жин) (January 25, 1917 – May 28, 2003) was a Belgian physicist and Nobel Laureate chemist noted for his work on dissipative structures, complex systems, and irreversibility.

Prigogine was born in Moscow, Russia and studied chemistry at the Université Libre de Bruxelles in Brussels, Belgium. In 1959, he was appointed director of the International Solvay Institute in Brussels, Belgium. He was later appointed Regental Professor and Ashbel Smith Professor of Physics and Chemical Engineering at the University of Texas at Austin in the United States, where in 1967 he co-founded what is now called the Center for Complex Quantum Systems.

Prigogine is known best due to his definition of dissipative structures and their role in thermodynamic systems far from equilibrium, a discovery that won him the Nobel Prize in Chemistry in 1977.

Dissipative structure theory led to pioneering research in self-organizing systems, as well as philosophic inquiries into the formation of complexity on biological entities and the quest for a creative and irreversible role of time in the natural sciences.

His work is seen by many as a bridge between natural sciences and social sciences. With University of Texas at Austin professor Robert Herman, he also developed the basis of the two fluid model, a traffic model for urban networks, using Bose-Einstein Condensation theory in traffic engineering.

In his later years, his work concentrated on the mathematical role of determinism in nonlinear systems on both the classical and quantum level. He proposed the use of a rigged Hilbert space in quantum mechanics as one possible method of achieving irreversibility in quantum systems. He also co-authored several books with Isabelle Stengers, including The End of Certainty and the classical book La Nouvelle Alliance.

Prigogine was the author of several scientific articles and books. He was a member of numerous scientific organizations, and received numerous awards, prizes and 53 honorary degrees. In 1955 Ilya Prigogine was awarded the Francqui Prize for Exact Sciences. He was awarded the 1977 Nobel Prize in Chemistry. In 1989, he was awarded the title of Viscount by the King of Belgium.
