Little is known about the life of Grigori Perelman outside of his work in mathematics and mathematical upbringing. There are probably more accounts of failed communication attempts than actual interviews of him.
I personally find disgusting that many existing accounts of Perelman portray his life in a rather negative light (living with his mother and sister, never cutting his beard…) It also shows how some of these journalists only know a handful of scientists and among them the extroverts are probably overrepresented.
While it’s not the rule, it’s also not rare to find other introverts like Perelman—after all, the academic life can be lead with minimal human interaction and lots of alone time.
I had a professor much like him last year. The only time I ever entered his office, I couldn’t make heads or tails of the paper he was reading, or even the abstract. I only know it was about optics because it was part of the journal name. What was he working on? Impossible to know now, but I couldn’t shake the idea that a man much like him but on the other side of the world one day announced this astonishing result. Who else could be the next?
Probably another silent person that has «eccentricities».
