Maira Kalman posts a charming illustrated story about Ben Franklin and the nature of invention:
I don’t think he was ever bored. He saw a dirty street and created a sanitation department. He saw a house on fire and created a fire department. He saw sick people and founded a hospital. He started our first lending library. He saw people needing an education and founded a university. He started the American Philosophical Society where men and women shared developments in science. And then, by the way, he helped create and run the country. He was a signer of both the Declaration of Independence and the Constitution.
