Franklin has indeed been aptly called "many-sided." He was eminent in science and public service, in diplomacy and in literature. He was the Edison of his day, turning his scientific discoveries to the benefit of his fellow-men. He perceived the identity of lightning and electricity and set up the lightning rod. He invented the Franklin stove, still widely used, and refused to patent it. He possessed a masterly shrewdness in business and practical affairs. Carlyle called him the father of all the Yankees. He founded a fire company, assisted in founding a hospital, and improved the cleaning and lighting of streets. He developed journalism, established the American Philosophical Society, the public library in Philadelphia, and the University of Pennsylvania. He organized a postal system for the colonies, which was the basis of the present United States Post Office. Bancroft, the eminent historian, called him "the greatest diplomatist of his century." He perfected the Albany Plan of Union for the colonies. He is the only statesman who signed the Declaration of Independence, the Treaty of Alliance with France, the Treaty of Peace with England, and the Constitution. As a writer, he has produced, in his _Autobiography_ and in _Poor Richard's Almanac_, two works that are not surpassed by similar writing. He received honorary degrees from Harvard and Yale, from Oxford and St. Andrews, and was made a fellow of the Royal Society, which awarded him the Copley gold medal for improving natural knowledge. He was one of the eight foreign associates of the French Academy of Science. The careful study of the _Autobiography_ is also valuable because of the style in which it is written. If Robert Louis Stevenson is right in believing that his remarkable style was acquired by imitation then the youth who would gain the power to express his ideas clearly, forcibly, and interestingly cannot do better than to study Franklin's method. Franklin's fame in the scientific world was due almost as much to his modest, simple, and sincere manner of presenting his discoveries and to the precision and clearness of the style in which he described his experiments, as to the results he was able to announce. Sir Humphry Davy, the celebrated English chemist, himself an excellent literary critic as well as a great scientist, said: "A singular felicity guided all Franklin's researches, and by very small means he established very grand truths. The style and manner of his publication on electricity are almost as worthy of admiration as the doctrine it contains."
