Charles Sebastian Dooin (1879-1952) played nearly all of his long and successful catching career for the Phillies, 1902-14. He batted .240, managed the club for 5 years and nurtured the young Grover Cleveland Alexander in his early years. Still holds the Phillies team record for games caught. Despite his small stature, was known for his fearless plate-blocking.

• Dooin always claimed Roger Bresnahan got the idea for shin guards from him in 1906
• After the Depression wiped out his wealth, used his rich baritone on the vaudeville circuit
