Cornelius Vanderbilt (May 27, 1794 – January 4, 1877), nicknamed "the Commodore", was an American business magnate who built his wealth in railroads and shipping. After working with his father's business, he worked his way into leadership positions in inland and coastal shipping, then invested in the rapidly growing railroad industry, effectively transforming the geography of the United States.
As one of the richest Americans in history and wealthiest figures overall, Vanderbilt was the patriarch of the wealthy and influential Vanderbilt family. He provided the initial gift to found Vanderbilt University in Nashville, Tennessee. For his monopoly on shipping and the railroads, facilitated in part by political manipulation, Vanderbilt is often described as either a "captain of industry" or a "robber baron".
