A. Bartlett Giamatti

Giamatti was inducted into the National Italian American Sports Hall of Fame in 1992.

Fay Vincent, Giamatti's close friend and baseball's first deputy commissioner, became acting commissioner upon Giamatti's death, and was quickly elected by MLB owners to succeed Giamatti as the new commissioner. On October 14, 1989, before Game 1 at the World Series, Giamatti—to whom this World Series was dedicated—was memorialized with a moment of silence. Son Marcus Giamatti threw out the first pitch before the game. Also before Game One, the Yale Whiffenpoofs sang the national anthem, a blend of "The Star-Spangled Banner" with "America the Beautiful" that has been since repeated by other a cappella groups.

While still serving as National League president, Giamatti suspended Pete Rose for 30 games after Rose shoved umpire Dave Pallone on April 30, 1988. Later that year, Giamatti also suspended Los Angeles Dodgers pitcher Jay Howell for three days, after Howell was caught using pine tar during the National League Championship Series.

Giamatti, whose tough dealing with Yale's union favorably impressed Major League Baseball owners, was unanimously elected to succeed Peter Ueberroth as commissioner on September 8, 1988. He formally took office on April 1, 1989. Determined to maintain the integrity of the game, on August 24, 1989, Giamatti prevailed upon Pete Rose to agree voluntarily to remain permanently ineligible to play baseball.

Giamatti served as president of Yale University from 1978 to 1986. He was the youngest president of the university in its history and presided over the university during a bitter strike by its clerical and technical workers in 1984–1985. As university president, he refused student, faculty, and community demands to divest from apartheid South Africa. He also served on the board of trustees of Mount Holyoke College for many years, participating fully despite his Yale and baseball commitments. Giamatti was elected a fellow of the American Academy of Arts and Sciences in 1980 and a member of the American Philosophical Society in 1982.

Giamatti had a lifelong interest in baseball and was a noted Boston Red Sox fan. In 1978, when he was first rumored to be a candidate for the presidency of Yale, he had deflected questions by observing that "The only thing I ever wanted to be president of was the American League." His noteworthy baseball publications include "Tom Seaver's Farewell", published in Harper's Magazine in September 1977, and "Baseball and the American Character," published in that magazine in October 1986. Giamatti became president of the National League in 1986, and later commissioner of baseball in 1989. During his stint as National League president, Giamatti placed an emphasis on the need to improve the environment for the fan in the ballparks. He also decided to make umpires strictly enforce the balk rule and supported "social justice" as the only remedy for the lack of presence of minority managers, coaches, or executives at any level in Major League Baseball.

Giamatti taught briefly at Princeton but spent most of his academic life at Yale. His scholarly work focused on English Renaissance literature, particularly Edmund Spenser, and relationships between English and Italian Renaissance poets. His tenure as Stiles master ended in 1972.

Giamatti stayed in New Haven to receive his doctorate in 1964, when he also published a volume of essays by Thomas G. Bergin he had co-edited with a philosophy graduate student, T. K. Seung. He became a professor of comparative literature at Yale University, an author, and master of Ezra Stiles College at Yale, a post to which he was appointed by his predecessor as Yale president, Kingman Brewster, Jr.

In 1960, he married Toni Marilyn Smith, who taught English for more than 20 years at the Hopkins School in New Haven, Connecticut, until her death in 2004. Together the couple had three children: actors Paul and Marcus and jewelry designer Elena.

While at his vacation home in Edgartown on Martha's Vineyard, Giamatti, a heavy smoker for many years, died suddenly of a heart attack at the age of 51, eight days after banishing Pete Rose and 154 days into his tenure as commissioner. He was interred at Grove Street Cemetery in New Haven, Connecticut. He became the second baseball commissioner to die in office, the first being Kenesaw Mountain Landis in 1944.

Angelo Bartlett Giamatti (/dʒiːəˈmɑːti/; April 4, 1938 – September 1, 1989) was an American professor of English Renaissance literature, the president of Yale University, and the seventh Commissioner of Major League Baseball.

Giamatti was born in Boston and grew up in South Hadley, Massachusetts, the son of Mary Claybaugh Walton (Smith College 1935) and Valentine John Giamatti. His father was professor and chairman of the Department of Italian Language and Literature at Mount Holyoke College. Giamatti's paternal grandparents were Italian immigrants Angelo Giammattei (Italian pronunciation: [dʒammatˈtɛi]) and Maria Lavorgna (Italian pronunciation: [laˈvɔrɲa; -orɲa]): his grandfather Angelo emigrated to the United States from Telese, near Benevento, Italy, around 1900. Giamatti's maternal grandparents, from Wakefield, Massachusetts, were Helen Buffum (Davidson) and Bartlett Walton, who graduated from Phillips Academy Andover and Harvard College. Giamatti attended South Hadley High School, spent his junior year at the American Overseas School of Rome, and graduated from Phillips Academy in 1956. At Yale College, he was a member of Delta Kappa Epsilon (Phi chapter) and as a junior in 1960 was tapped by Scroll and Key, a senior secret society. He graduated magna cum laude in 1960.
