Franklin invented the lightning rod and never accepted royalties from the manufacture and sale of them. He did the same with the Franklin Stove. He respected property and property rights, but was extremely generous with his own. The royalties from either of those inventions would have made him separate fortunes.
His life was one of the most fascinating stories I've ever heard or read. Great choice.
But since you mentioned favorites, I have to go with Jefferson. He was a flawed man...an abolitionist who owned slaves, a man who loathed the Federal government and its power, yet purchased the Louisiana territory without Congress' permission...but his ultimate philosophy is something I think of as important as the revolution itself. Plus, I urge every American to actually read the Declaration of Independence. A document that, when read, remains as powerful as it did 234 years ago. Thankfully, the Founding Fathers picked the absolute right man to be its author.
I have no vote although I thought that was funny when I first heard it.
Go down south and look in the Yellow Pages and you are likely to see thousands of Washington's and Jefferson's. There's a reason for that.
