Editor's Take:

Franklin may be the most well-rounded of America's founders, equally at home in a print shop, a laboratory or a royal court. He rose from humble beginnings as a printer's apprentice to become a publisher, writer and civic organiser, founding a library, a fire company and a university in Philadelphia. His famous experiments with electricity, including flying a kite in a storm, made him internationally renowned. As a diplomat in France, he secured the alliance that helped America win independence. His wit and practical wisdom, in sayings like 'Early to bed and early to rise', are still widely quoted.
