Henry Chadwick was an English-American sportswriter, baseball statistician and historian, often called the "Father of Baseball" for his early reporting on and contributions to the development of the game. He edited the first baseball guide that was sold to the public. He is credited with creating box scores, as well as creating the abbreviation "K" that designates a strikeout. He was posthumously inducted into the National Baseball Hall of Fame in 1938.

A box score is a chart used in baseball to present data about player achievement in a particular game. An abbreviated version of the box score, duplicated from the field scoreboard, is the line score. The Baseball Hall of Fame credits Henry Chadwick with the invention of the box score in 1858.
