7.- Jay Gould

gouldSource

A Railroad baron and gold speculator. He amassed  a fortune of $71.2 billion. He also masterminded the 19th century transportation boom in the United States. And, along with financier James Fisk, purchased a share in the gold market large enough to affect market movements at the time. A Machiavellian tycoon in every way. Also, a Pisces.
