LOL I opened this thread just to post a link to the Quanta magazine site. It's a very well done article and applies a great human element to the story. Dementia is one of the few things that scares me.

For an amateur mathematician to do this is, as you say, a surprising feat. I'd go beyond that to add a bunch more superlatives.

I highly recommend the link you provided. It's a bit long but well written.

And another that I just found and read:
