P.T. Barnum was huckster, con man, promoter and entertainer. His American Museum featured ancient relics side by side with such "living curiosities" as lions, snakes, bearded ladies and Siamese twins. In 1871 he took the whole show on the road; it traveled by rail. Barnum introduced the idea of three rings, and his "Jumbo the Elephant" added a new word to the English language. By the time he teamed up with James Bailey, his circus had become "The Greatest Show on Earth."
