What recent discoveries have amateur mathematicians made?

Dear overflowers

Out of curiosity: do you know any famous papers and/or results by non professional mathematicians? (I realize that 'non professional mathematicians' is quite vague, so let's also say 'amateur'?) Thank you for your answers!

Edit: I meant of course math papers. Also, I am interested in somewhat recent examples, say the last 2 centuries.
