the 19th century, would make him one of the wealthiest men in the world. Starting with a single boat, he grew his fleet until he was competing with Robert Fulton for dominance of the New York waterways, his energy and eagerness earning him the nickname "Commodore", a United States Navy title for a captain of a small task force. Fulton's company had established a monopoly on trade in and out of New York Harbor. Vanderbilt, based in New Jersey at the time, flouted the law, steaming in and out of the harbor under a flag that read, "New Jersey Must Be Free!" He also hired the attorney Daniel Webster to argue his case before the United States Supreme Court; Vanderbilt won, thereby establishing an early precedent for the United States' first laws of interstate commerce. While many Vanderbilt family members had joined the Episcopal Church, Cornelius Vanderbilt remained a member of the Moravian Church to his death. The Vanderbilt family lived on Staten Island until the mid-1800s, when the Commodore built a house on Washington Place (in what is now Greenwich Village). Although he always occupied a relatively modest home, members of his family would use their wealth to build magnificent mansions. Shortly before his death in 1877, Vanderbilt donated US$1 million (equivalent to $ million in ) for the establishment of Vanderbilt University in Nashville. The Commodore left the majority of his enormous fortune to his eldest son, William Henry Vanderbilt. William Henry, who outlived his father by just eight years, increased the profitability of his father's holdings, increased the reach of the New York Central Railroad, and doubled the Vanderbilt wealth. He built the first of what would become many grand Vanderbilt mansions on Fifth Avenue, at 640 Fifth Avenue. William Henry appointed his first son, Cornelius Vanderbilt II, as the next "Head of House". Cornelius II built the largest private home in New York, at 1 West 58th Street, containing approximately 154 rooms, designed by George B. Post. He also built The Breakers in Newport, Rhode Island. Cornelius II's brother, William Kissam Vanderbilt, also featured prominently in the family's affairs. He also built a home on Fifth Avenue and would become one of the great architectural patrons of the Gilded Age, hiring the architects for (the third, and surviving) Grand Central Terminal. He also built Marble House at 596 Bellevue Avenue in Newport, Rhode Island. George Washington
