History's Famous Figure

No we are not talking about Winston Churchill, not even about Issac Newton, I am referring to this person called Che Guevara, the Bolivian revolutionary fighter. I don't understand the hype surrounding the man of seeming mythical proportions. People like David Beckham, Mike Tyson had his image tattooed onto their bodies and a number of people wearing T-shirts adorned with his image? Who the hell is he anyway..and why is he so famously cool?? A check in Wikipedia to find out..
