As manager George Frederick "Foghorn" or "Calliope" Miller (August 15, 1864 – April 6, 1909) was an American professional baseball catcher.

He played in Major League Baseball (MLB) from 1884 through 1896 for the Pittsburgh Alleghenys / Pirates, St. Louis Browns, and Louisville Colonels.

Primarily a catcher, Miller shunned the protective equipment that was becoming standard for that position, and that made catching too physically demanding to do every day.

[2] His nickname, "Doggie", alluded to his hobby of dog breeding,[3] but Miller was sometimes also known as "Calliope" or "Foghorn" – references to his gruff voice and boisterous manner – especially early in his career.

[4] He became known for some characteristic mannerisms, including what sportswriter Hugh Fullerton described as "a funny little ballet girl kick" just before he swung the bat.

Von der Ahe, notorious for meddling in the field management of his teams, promised Miller that he would not interfere.

[10] During one game that year, von der Ahe sent the team's official scorer down to the field to replace a hungover Miller as manager for the day.

[1] When he was not on the field, Miller performed in the Wild West show that von der Ahe had bought from Buck Taylor.

Miller came back as a player in 1895, but von der Ahe hired Al Buckenberger to step in as manager.

Early that year, newspaper reports held that Cap Anson was interested in signing him to a major league contract.

Miller was arrested and was fined $100 by the team, and a newspaper report speculated that he might not be allowed to play professionally anymore.

Miller's co-owner, C. F. Baker of Fort Wayne, Indiana, failed to pay salaries, league fees and other bills.
