This is a parochial talk, based on my memory of events over a number of yea
rs. Thus I still remember the rather excited tone of Denis Jerome, telling
me on the telephone twenty years ago that he had at last observed supercond

but the field soon developed into a new country which Orsay helped to conqu
er. This is what we are celebrating today.
