A catcher in Major League Baseball during the first two decades of the 20th century, he played 1,219 of his 1,290 games as a member of the Philadelphia Phillies and managed the Phils from 1910 through 1914.

Moreover, along with fellow catcher and player-coach Pat Moran, he nurtured the great pitcher Grover Cleveland Alexander to stardom in his earliest big league seasons.

The Phillies rose to second place in the 1913 NL, but when they fell to sixth the following season, Dooin was replaced by Moran as the team's skipper.

Still an active player, he then was traded to the Cincinnati Reds and, ultimately, the New York Giants, where he played his final two seasons in the Majors.

[1] Dooin died of a heart attack in Rochester, New York at the age of 72, and was buried at Holy Sepulchre Cemetery.
