有声读物: Art of Money Getting

Phineas Taylor Barnum (July 5, 1810 – April 7, 1891) was an American showman, businessman, and entertainer, remembered for promoting celebrated hoaxes and for founding the circus that became the Ringling Bros. and Barnum & Bailey Circus.
His successes may have made him the first "show business" millionaire. Although Barnum was also an author, publisher, philanthropist, and for some time a politician, he said of himself, "I am a showman by profession...and all the gilding shall make nothing else of me," and his personal aims were "to put money in his own coffers".
