Michael Francis Atiyah has had a remarkably long and productive career that is based in topology but encompasses such diverse fields as algebraic geometry, differential equations, and theoretical physics. In recognition of three major theorems he developed during the first decade of his career, he was awarded the Fields Medal in 1966. Atiyah is also one of the pioneers of string theory, a new way of looking at the structure of matter. Claude LeBrun wrote in American Scientist that Atiyah has "played the role of the great unifier for a swath of mathematical subfields that had been developing into autonomous petty fiefdoms, oblivious to the outside world." He has also served in various capacities to help guide the scientific policy of the British government and has been an articulate spokesperson for the importance of theoretical research.

Atiyah was born in London on April 22, 1929. His father was Edward Selim Atiyah...
