"Ice Box" Chamberlain (November 5, 1867 – September 22, 1929) was an American professional baseball pitcher.
He pitched in Major League Baseball for ten seasons between 1886 and 1896.
In several seasons, Chamberlain finished in his league's top ten in a number of pitching categories, including wins, earned run average, strikeouts, and shutouts.
During one of his best seasons, the 1888 St.
Louis Browns won the American Association pennant with a 92–43 record.
Although a righthanded pitcher, Chamberlain pitched the last two innings of an 1888 game with his left hand.
Chamberlain finished his major league career with 264 complete games out of his 301 games started.
After his playing days, he was hired as a baseball umpire and later announced that he was becoming a boxer, but neither venture seems to have worked out.
