the early 1900s, the Vanderbilts developed a pair of residences at 645 and 647 Fifth Avenue. George was the first owner of number 647. Biltmore Living in one or another of his family residences well into adulthood, Vanderbilt decided to construct his own country mansion and estate in 1888. For this purpose, he acquired 125,000 acres of woodland in North Carolina, employing the architect Richard Morris Hunt to design a limestone house modeled on the Chateau de Blois and other chateaux of the Loire Valley. With up to four acres of floor space, this is believed to be the largest domestic dwelling ever constructed in the United States. At Biltmore, Vanderbilt 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, Frederick Law 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 also the site of the Biltmore School of Forestry, the first such school in North America, established in 1898 by Dr. Carl A. Schenck. Vanderbilt was known for his generosity toward his employees at Biltmore. Every year, he held a Christmas celebration for their children, complete with decorated tree and presents for each child, even those who could not make it to the party. He also paid all the expenses of the Cathedral of All Souls, an Episcopal cathedral he'd built and was a parishioner of, located directly across from the Biltmore Estate's main gate in Biltmore Village (the model village he had built for those who had worked to build the Estate or were employed on the Estate), so that the church's weekly collection could go directly to charity and outreach. Family On June 1, 1898, Vanderbilt married Edith Stuyvesant Dresser (January 17, 1873 – December 21, 1958) at the American Cathedral in Paris, France. George and Edith had one daughter together, Cornelia Stuyvesant Vanderbilt (August 22, 1900 - February 7, 1976). In 1912, George and Edith booked passage on the doomed Titanic, but they changed their plans at the last minute via telephone, instead sailing on her sister ship, the Olympic. The Olympic
