W. Elst at the European Southern Observatory. Edward Witten (b. 1951) is a physicist at the Institute for Advanced Study in Princeton and one of the premier theoretical physicists of our time. He has made fundamental contributions to particle physics and string theory. In 1990 he was awarded the Fields Medal, the highest prize in mathematics.
