Jackie Robinson attended John Muir High School, formally Muir Tech, in Pasadena, Calif. While in high school, Robinson excelled in four sports: basketball, track, football and baseball.

Robinson began his professional baseball career in 1945. He played 47 games for the Kansas City Monarchs. Due to his frustration with the lack of organization in the Negro Leagues, Robinson began pursuing opportunities to play in the Major Leagues. On April 15, 1947, Robinson played his first game for the Brooklyn Dodgers, becoming the first African-American major league baseball player. In 2004, the MLB began celebrating Robinson's achievement with Jackie Robinson Day. In 2013, Robinson was portrayed by actor Chadwick Boseman in a biopic titled "42."
