DESCRIPTION:Jean-Claude Hausmann\, Université de Genève\nIn 1956\, John
  Milnor astonished the mathematical community by discovering exotic sphere
 s\, i.e. smooth manifolds homeomorphic but not diffeomorphic to a standard
  sphere. Less than seven year later\, exotic spheres in high dimensions we
 re fully classified up to diffeomorphism by the work of Kervaire-Milnor\, 
 which gave birth to surgery theory. These important achievements have been
  possible thanks to great advances in differential topology\, as well as i
 n homotopy theory. This talk will survey those effervescent years in topol
 ogy.
