First, yesterday, we find that Physics winner Donna Strickland did not have a page. She had one four years ago briefly, but it had been quickly deleted on notability grounds.
And now today we get a Chemistry winner, George P. Smith, who also did not have a page--not even an old deleted page. His first page was created this morning after the Prize was announced.
This also happened last year, also in Chemistry, with Jacques Dubochet.
