I saw a thread like this some time ago, but thought I'd start another just for fun. List your top 5 favorite mathematicians. These don't necessarily have to be who you feel are the "best", but just the five that you have the most respect for or interest in. Here's my five: 1. Gauss 2. Euler 3. Newton 4. Archimedes 5. Riemann [Edit] If anyone would like to discuss works or ideas by someone in your list, feel free.
