This thought randomly sprang into my head late last night after I read a reference to King Arthur and wondered whether he was the greatest ever Englishman. I then wondered who you guys would consider the greatest ever American? Who embodies what you believe is the best of your nation?
No poll, just interested to read a few opinions. If it's somebody who you think isn't amazingly well known, add a summary of their most poignant achievements please. Don't feel limited by politics, gender or religion, if you think an author, actor, industrialist or other fits the bill, I'd like to hear why.
