Prigogine

Viscount Ilya Romanovich Prigogine (; Russian: Илья Романович Пригожин; 25 January [O.S. 12 January] 1917 – 28 May 2003) was a Belgian physical chemist of Russian origin, noted for his work on dissipative structures, complex systems, and irreversibility. Prigogine's work most notably earned him the 1977 Nobel Prize in Chemistry “for his contributions to non-equilibrium thermodynamics, particularly the theory of dissipative structures”, as well as the Francqui Prize in 1955, and the Rumford Medal in 1976.
