Even before moving to Pennsylvania almost three decades ago, I had admired Benjamin Franklin. Not only was he an author, publisher, diplomat, postmaster, political theorist, and one of the founding fathers of USA, but he was also a first-rate technoscientific researcher. Anyone who has seen the numerous fierce storms that sweep the Atlantic seaboard would be glad to learn that Franklin invented the lightning rod. He also invented bifocal glasses, a stove that heats better than an open fireplace yet spews out much less smoke, and a flexible urinary catheter for immobile patients—all devices in common use more than two centuries later. He was the first to map the Gulf Stream to produce navigation charts that trimmed the transatlantic sailing time by two weeks. Spreading snatches of cloth of different colors on snow, he determined the scientific reason for wearing dark clothes in winter to keep warm and light clothes in summer to keep cool. With his most famous experiment that gave him a frightening jolt, he ascertained that lightning is electricity.
