Deletion of Robert Berger (mathematician)

Comment: For starters, that "one paper" was a significant result: the demonstration that there are indeed aperiodic tilings -- such tilings were previously unknown (and unanticipated) in the history of mathematics.   reads in part, "If the event is highly significant, and the individual's role within it is a large one, a separate article is generally appropriate."  Further, this is "one paper" is a highly cited article; since someone took the time to look at MathSciNet, surely they know this.  Last, |Wikipedia is not paper.  This isn't blog-like or self-promotional; it isn't an entry in a directory; it is a tub|stub that merits further expansion
