Shipping and railroad tycoon Cornelius Vanderbilt (1794-1877) was a self-made multi-millionaire who became one of the wealthiest Americans of the 19th century. As a boy, he worked with his father, who operated a boat that ferried cargo between Staten Island, New York, where they lived, and Manhattan. After working as a steamship captain, Vanderbilt went into business for himself in the late 1820s, and eventually became one of the country’s largest steamship operators. In the process, the Commodore, as he was publicly nicknamed, gained a reputation for being fiercely competitive and ruthless. In the 1860s, he shifted his focus to the railroad industry, where he built another empire and helped make railroad transportation more efficient. When Vanderbilt died, he was worth more than $100 million.
