The Henri Poincaré Prize 1997 was awarded to Arthur Wightman for his
central role in the foundations of the general theory of quantized
fields, the powerful impetus impressed promoting resarch on various
aspects of Modern Mathematical Physics (on constructive QFT, and on
domains ranging from statistical mechanics, dynamical systems and
ergodic theory to integrable systems, Schroedinger Operators and
renormalization theory), for his expository contributions of a
masterly level to mathematical physics.
