Bob Hart was an American League umpire in 1912 and 1913, and then umpired in the National League from 1920 to 1929. Altogether, he umpired over 1,700 major league games and worked in the 1923 World Series. He was behind the plate for the game on May 1, 1920 during which Joe Oeschger and Leon Cadore both pitched 26 innings.
Hart played minor league baseball from 1900 to 1906, but his playing career ended when he broke his leg in 1906, playing for a semi-pro team in Maine. In 1907, he turned to umpiring, first in the Ohio-Pennsylvania League, and then in the Ohio State League (1908-1909), the Western League (1909), the Connecticut League (1910), the New York State League (1910), the Eastern League/International League (1911-1918, during which he also umpired two seasons in the America League) and the American Association (1919-1920).
After his stint in the National League, he was named umpire-in-chief of the New England League in 1930. He managed a polo team in the off-season and was the captain of the Hartford "roller-polo" team. He was also involved in local politics in Lowell, MA, serving as a town assessor, and died there of a heart attack in 1937, aged 57.
