(August 31, 1915 – July 8, 1990) was an owner and club president of the Philadelphia Phillies of American Major League Baseball.
When he took command of the Phillies in November 1943 after his father purchased the franchise, the 28-year-old Carpenter became the youngest club president in baseball history.
He became principal owner upon his father's death in 1949 and would serve as president of the Phillies until 1972, when his son succeeded him.The Carpenter family owned the Phillies from 1943 to 1981, winning National League championships in 1950 and 1980, National League East Division titles in 1976, 1977, 1978, and 1980, and the team's first World Series title in 1980.
Distressed by the free-spending, free-agent era, and anticipating the 1981 baseball strike, the Carpenters sold the Phils months after their World Series triumph.
The team made the 1981 playoffs, and won the 1983 NL pennant under its new owners.
