Robert Liston

I, like many people, get stuck on Wikipedia on a regular basis whenever I start reading about anything interesting. Until now, I've never felt the need to share, but I have a service to the anti-social community in entertaining them, so here goes my first attempt at sharing something you could just as easily find yourself. 

Robert Liston was a Scottish surgeon who was apparently a badass at amputation and able to do it faster than anyone else. Unfortunately, he sometimes amputated more than was necessary. Unfortunately, malpractice was a long way off. 

His most famous case apparently involved amputating a leg in record time, accidentally amputating his assistant's fingers, too, and then amputating the coat tails of a spectator, all of which died, two from infection, and one from fright. Triple-kill achievement unlocked.
