Wow! I guess if you need exaggeration - go for it.
I suggest you read Ron Chernows biography, Titan. Many years ago , I read Nevinss go at his life. But Chernow makes the man come to life. Consider how huge an enterprise Standard Oil became, They used to speak of Captains of Industry. Men like him, and Vanderbilt, Jay Gould, Tom Scott , and Carnegie deserve that description, because what they were doing was empire building..literally.
