Connie Mack

"Cornelius McGillicuddy, Sr. (December 22, 1862 – February 8, 1956), better known as Connie Mack, was an American professional baseball player, manager, and team owner. The longest-serving manager in Major League Baseball history, he holds records for wins (3,731), losses (3,948), and games managed (7,755), with his victory total being almost 1,000 more than any other manager. Mack managed the Philadelphia Athletics for the club's first 50 seasons of play, starting in 1901, before retiring at age 87 following the 1950 season, and was at least part-owner from 1901 to 1954. He was the first manager to win the World Series three times, and is the only manager to win consecutive Series on separate occasions (1910–11, 1929–30); his five Series titles remain the third most by any manager, and his nine American League pennants rank second in league history. However, constant financial struggles forced repeated rebuilding of the roster, and Mack's teams also finished in last place 17 times. Mack was elected to the Baseball Hall of Fame in 1937."

Connie Mack and the Early Years of Baseball
"... This book brings to life the unruly origins of baseball as a sport and a business and provides the first complete and accurate picture of a character who was larger than life and yet little known: the tricky, rule-bending catcher; the peppery field leader and fan favorite; the hot-tempered young manager. Illustrated with previously unpublished family photographs, it affords unique insight into a colorful personality who helped shape baseball as we know it today."

Connie Mack: The Turbulent and Triumphant Years, 1915-1931
"The Philadelphia Athletics dominated the first fourteen years of the American League, winning six pennants through 1914 under the leadership of their founder and manager, Connie Mack. But beginning in 1915, where volume 2 in Norman L. Macht’s biography picks up the story, Mack’s teams fell from pennant winners to last place and, in an unprecedented reversal of fortunes, stayed there for seven years. World War I robbed baseball of young players, and Mack’s rebuilding efforts using green youngsters of limited ability made his teams the objects of public ridicule."
