P.T. Barnum worked with many performers. Perhaps the most famous was the diminutive General Tom Thumb. Barnum also promoted Swedish singer Jenny Lind, but his biggest act was Jumbo the Elephant, an African elephant he bought from the London Zoo.
P.T. Barnum is best known as a circus man, but he spent most of his career running a curiosity museum and staging freak shows. Barnum attracted people to his American Museum through shrewd advertising, or "humbug." He also wasn't afraid of a hoax.
