A completely objective ranking of the top 5 mathematicians of history. And with all due respect, no I did not forget about Newton....
  1. Leonhard Euler
    *The Master of us All*
  2. Carl Gauss
    *The Prince of Mathematics*
  3. Archimedes
    Originated the important tradition of mathematicians making great discoveries while bathing.
  4. Alexander Grothendieck
    Possibly influenced the last half of 20th century mathematics more than anyone else. Also just a fascinating dude. I'm still waiting for part 3 of Scharlau's biography to be translated into English.
  5. Euclid
    It's weird to imagine how different mathematics would look like if *Elements* had never happened.
