Howard Brush Dean III (born November 17, 1948) is an American physician, author and retired politician who served as the 79th Governor of Vermont from 1991 to 2003 and Chair of the Democratic National Committee (DNC) from 2005 to 2009. Dean was a candidate for the Democratic nomination in the 2004 presidential election. His implementation of the fifty-state strategy as head of the DNC is credited with the Democratic victories in the 2006 and 2008 elections. Afterward, he became a political commentator and consultant to McKenna Long & Aldridge, a law and lobbying firm.

Dean was born in East Hampton, New York, to Andree Belden (nee Maitland), an art appraiser, and Howard Brush Dean, Jr., an executive in the financial industry.  He is the eldest of four brothers, including Jim Dean, Chair of Democracy for America, and Charles Dean, who was captured by the Pathet Lao and executed by the North Vietnamese while traveling through Southeast Asia in 1974.  Howard's father worked at the stock brokerage firm of Dean Witter. The family was quite wealthy, Republican, and belonged to the exclusive Maidstone Golf Club in East Hampton. As a child he spent much of his time growing up in East Hampton; the family built a house on Hook Pond there in the mid-1950s. There the boys- Howard, Charlie, Jim and Bill- "rode bikes, played with a model train set, [and] built elaborate underground forts." While in New York, the family had a three-bedroom apartment on the Upper East Side along Park Avenue.  Howard attended the Browning School in Manhattan until he was 13, and then went to St. George's School, a preparatory school in Middletown, Rhode Island. In September 1966, he attended Felsted School, UK, for one school year after winning an English Speaking Union scholarship.  Political opponents have been reluctant to seize upon Dean's privileged early life. UPI quoted one of Dean's friends in his youth as saying, "By Hamptons standards, the Deans were not rich. No safaris in Africa or chalets in Switzerland. Howard's father went to work every day. He didn't own a company, or have a father or grandfather who founded one, as mine did." Peggy Noonan wrote in the Wall Street Journal that  "he doesn't seem like a WASP. I know it's not nice to deal in stereotypes, but there seems very little Thurston Howell, III, or George Bush, the elder, for that matter, in Mr. Dean.... He seems unpolished, doesn't hide his aggression, is proudly pugnacious. He doesn't look or act the part of the WASP...It will be harder for Republicans to tag Mr. Dean as Son of the Maidstone Club than it was for Democrats to tag Bush One as Heir to Greenwich Country Day. He just doesn't act the part."
