Vanderbilt was one of the original members of the
Westchester Racing Association and a driving force behind
thoroughbred racing in America for most of the 20th century. His mother,
Margaret Emerson, took him to his first race, the
Preakness Stakes, in 1922. He often said, "After that, I was hooked." On his 21st birthday, his mother gave him
Sagamore Farm, her racing operation in
Reisterstown, Maryland, which she had inherited from her father,
Isaac Emerson, who invented
Bromo-Seltzer and founded the Emerson Drug Company, which later became
Warner-Lambert. Vanderbilt personally oversaw the breeding and training of his stable. His first major acquisition was
Discovery, one of the great handicap horses of the age, who became his foundation sire. At age 20 in 1932, he bought
Pimlico Race Course outside Baltimore. Three years later, Vanderbilt was elected to
The Jockey Club, the youngest member in its history. In 1938, he arranged the famous match race between
Seabiscuit and
War Admiral. He was president of Belmont Park and Pimlico at the same time before joining the Navy. During World War II, he captained a
PT boat in the South Pacific and was awarded the
Silver Star for bravery under fire. He then returned to racing, bringing his greatest champion,
Native Dancer, to the track in 1952. Native Dancer won all 9 starts as a 2-year-old and was named Horse of the Year. He won every start as a three-year-old except the
Kentucky Derby, which he lost by a head to
Cain Hoy Stable's
Dark Star. Still, Native Dancer was named 3-year-old Male Champion and was
Horse of the Year again in his 4th year. All told, he won 21 of 22 starts, with the single second-place finish in the 1953 Kentucky Derby his only career loss. Many consider
the Grey Ghost of Sagamore to have been the first Thoroughbred television star, and
TV Guide ranked him as a top icon of the era". He eventually campaigned four national champions: Discovery, Next Move,
Bed O' Roses, and Native Dancer. Vanderbilt continued racing throughout his life and served as chairman of the board of the
New York Racing Association from 1971 to 1975. The New York Turf Writers voted him "The Man Who Did The Most for Racing" a record four times, posthumously renaming the award in his honor. ==Personal life==
