Thomas Kennerly Wolfe Jr. (born March 2, 1931) is an American author and journalist, best known for his association with and influence in stimulating the New Journalism literary movement, in which literary techniques are used extensively. He reduced traditional values of journalistic objectivity. He began his career as a regional newspaper reporter in the 1950s, but achieved national prominence in the 1960s following the publication of such best-selling books as The Electric Kool-Aid Acid Test (a highly experimental account of Ken Kesey and the Merry Pranksters), and two collections of articles and essays, Radical Chic & Mau-Mauing the Flak Catchers and The Kandy-Kolored Tangerine-Flake Streamline Baby. His first novel, The Bonfire of the Vanities, published in 1987, was met with critical acclaim, and also became a commercial success.

Wolfe was born in Richmond, Virginia, the son of Louise (nee Agnew), a landscape designer, and Thomas Kennerly Wolfe Sr., an agronomist. Wolfe grew up on Gloucester Road in the historic Richmond North Side neighborhood of Sherwood Park. He recounts childhood memories in a foreword to a book about the nearby historic Ginter Park neighborhood. Wolfe was student council president, editor of the school newspaper, and a star baseball player at St. Christopher's School, an Episcopal all-boys school in Richmond. Upon graduation in 1947, he turned down admission to Princeton University to attend Washington and Lee University, both all-male schools at the time. At Washington and Lee, Wolfe was a member of the Phi Kappa Sigma fraternity. Wolfe majored in English and practiced his writing outside the classroom as well. He was the sports editor of the college newspaper and helped found a literary magazine, Shenandoah. Of particular influence was his professor Marshall Fishwick, a teacher of American studies educated at Yale. More in the tradition of anthropology than literary scholarship, Fishwick taught his classes to look at the whole of a culture, including those elements considered profane. Wolfe's undergraduate thesis, entitled "A Zoo Full of Zebras: Anti-Intellectualism in America," evinced his fondness for words and aspirations toward cultural criticism. Wolfe graduated cum laude in 1951. Wolfe had continued playing baseball as a pitcher and had begun to play semi-professionally while still in college. In 1952 he earned a tryout with the New York Giants but was cut after three days, which Wolfe blamed on his inability to throw good fastballs. Wolfe abandoned baseball and instead followed his professor Fishwick's example, enrolling in Yale University's American studies doctoral program. His PhD thesis was titled The League of American Writers: Communist Organizational Activity Among American Writers, 1929-1942. In the course of his research, Wolfe interviewed many writers, including Malcolm Cowley, Archibald MacLeish, and James T. Farrell. A biographer remarked on the thesis: "Reading it, one sees what has been the most baleful influence of graduate education on many who have suffered through it: it deadens all sense of style." His thesis was originally rejected but it was finally accepted after he rewrote it in an objective rather than a subjective style. Upon leaving Yale, he wrote a friend explaining through expletives his personal opinions about his thesis.
