George Washington Vanderbilt II (November 14, 1862 – March 6, 1914) was an art collector and member of the prominent Vanderbilt family, which had amassed a huge fortune through steamboats, railroads, and numerous business enterprises. He owned the 250-room Biltmore House, the largest home in the United States.
The youngest child of William Henry Vanderbilt and Maria Louisa Kissam. George II was named after his paternal uncle.
As the youngest of William's children, George II was said to be his father's favourite and his constant companion. Relatives described him as slender, dark-haired, and pale-complexioned. Shy and introverted, his interests ran to philosophy, books, and the collection of paintings in his father's large art gallery. In addition to frequent visits to Paris, France, where several Vanderbilts kept a home, George travelled extensively, fitting fluent in eight foreign languages.
His dad owned elegant mansions in New York City and Newport and an 800-acre (3.2 km 2 ) country estate on Long Island. When William passed away in 1885 of a stroke, he left a fortune of approximately $200 million, the bulk of which was split between his two older sons, Cornelius Vanderbilt II and William K. Vanderbilt. George W. Vanderbilt II inherited $1 million from his grandfather and received another million on his twenty-first birthday from his father. Upon his father's death, he inherited $5 million more, as well as the income from a $5 million trust fund. He ran the family farm at New Dorp and Woodland Beach, now the neighbourhood of Midland Beach on Staten Island, New York where he had been born, then lived with his mom in Manhattan until his own townhouse at 9 West 53rd Street was completed in 1887. The Vanderbilt family business was operated by his older brothers. This left George to spend his time in intellectual pursuits.
In 1891 he joined the New York Society of the Sons of the American Revolution.
At Biltmore, George led the life of a country gentleman. Having a great interest in horticulture and agriscience, he oversaw experiments in scientific farming, animal bloodline breeding, and silviculture (forestry). His goal was to run Biltmore as a self-sustaining estate. In 1892, Olmsted suggested that Vanderbilt hire Gifford Pinchot to manage the forests on the estate. According to Pinchot, who went on to be the first Chief of the United States Forest Service, Biltmore was the first professionally managed forest in the U.S; it was additionally the site of the Biltmore School of Forestry, the first such school in North America, established in 1898 by Dr. Carl A. Schenck.
On June 1, 1898, George W. Vanderbilt married Edith Stuyvesant Dresser (1873–1958) at the American Cathedral in Paris, France. They had one daughter, Cornelia Stuyvesant Vanderbilt (1900–1976). In 1912 George and Edith booked passage on the Titanic but changed their plans before departure, sailing and arriving in New York before the Titanic sank.
He passed away due to complications following an appendectomy in Washington, D.C.  He had been interred in the Vanderbilt family mausoleum at the Moravian Cemetery in New Dorp in Staten Island, New York.
After his death, George's widow sold approximately 86,000 acres (350 km 2 ) of the property to the United States Forest Service at $5 an acre, fulfilling her husband's wishes to create the core of Pisgah National Forest. She sold additional land as finances demanded; today, about 8,000 acres (32 km 2 ) remain. Edith Dresser Vanderbilt later married Peter Goelet Gerry (1879–1957), a United States Senator from Rhode Island. Cornelia Stuyvesant Vanderbilt (George and Edith Vanderbilt's only child) married British aristocrat, John F. A. Cecil, a descendant of William Cecil in 1924. Her sons, George and William, eventually inherited the property. George Cecil, the older of the two sons, chose to inherit the majority of the estate's land and the Biltmore Farms Company, which was more profitable than the house at the time. The younger son, William Cecil was thus left with Biltmore House, and is credited with preserving the chateau which (though still privately owned) has been opened to the public.
