Angelo Bartlett "Bart" Giamatti (April 4, 1938 - September 1, 1989) was the President of Yale University, and later, the 7th commissioner of Major League Baseball in the United States. Giamatti is best remembered for overseeing the banishment of popular baseball player Pete Rose from the sport for his gambling problems in 1989.

He grew up near Mount Holyoke College, in South Hadley, Massachusetts, where his father, Valentine Giamatti, founded the departments of Italian and Spanish languages and literatures. He also collected translations of Dante's Divine Comedy. His mother, Mary Claybaugh Walton, was the daughter of Helen (Davidson) Walton and Bartlett Walton, who attended Andover and Harvard College. His paternal grandfather, Angelo Giammattei (so spelled) emigrated from Italy through Ellis Island about 1900. Bart graduated from South Hadley High School, and while President of Yale, served as a Trustee of Mount Holyoke College.

A. Bartlett Giamatti attended Andover and Yale. He was pledged to Scroll & Key, and graduated magna cum laude in 1960, marrying Toni Smith that same year. Two of their three children, Marcus Giamatti, Paul Giamatti, and Elena Giamatti, have become actors. Bart stayed in New Haven to receive his doctorate in 1964. He became a professor of English at Yale University, an author, and master of Ezra Stiles College at Yale. He spent a brief period teaching at Princeton, but was at Yale for most of his teaching life. When his tenure as Stiles master ended in 1972, he was so popular that his students wanted to honor him with a present. Giamatti told them he wanted a joke gift and they got him a moosehead (from a yard sale), which was ceremoniously hung in the dining hall. As the new master took over, Giamatti told him in a serious tone, "I have only one solemn duty I have to convey to you. Take care of my moose."

He served as President of Yale University from 1977 to 1986. He was the youngest President of the University in its history. He served on the Board of Trustees of Mount Holyoke College for many years, participating fully in spite of his Yale and baseball commitments.

His life-long interest in baseball (Giamatti was a die-hard Boston Red Sox fan) came into play when he became President of the National League in 1986, and later Commissioner of Baseball in 1989. One of his main acts was the banishment for life of Pete Rose from baseball for betting on the sport and associating with known gamblers, detailed in the Dowd Report. Ironically, just a year earlier while still serving as National League president, Giamatti suspended Rose for 30 games after Rose shoved umpire Dave Pallone on April 30.

While at his vacation home in Martha's Vinyard Giamatti died rather suddenly of a massive heart attack at the age of 51, only eight days after banishing Rose. Bart Giamatti had only been the commissioner of baseball for 154 days.

Soon after his untimely passing, some pundits argued that the stress and subsequent agony from the investigation of Rose took its toll on Giamatti's health. While others have come to Rose's defense arguing that Giamatti's fatal heart attack was brought on by his diet and heavy smoking habit.

James Reston, Jr. notes, in his book Collision at Home Plate: The Lives of Pete Rose and Bart Giamatti, that Giamatti suffered from Charcot_Marie_Tooth disease, an inherited neuromuscular disease affecting peripheral nerves.
