Jack Roosevelt "Jackie" Robinson became the first African-American professional baseball player of the modern era in 1947. While not the first African American professional baseball player in history, his Major League debut with the Brooklyn Dodgers ended approximately eighty years of baseball segregation, also known as the baseball color line. The Baseball Hall of Fame inducted Robinson in 1962 and he was a member of six World Series teams. Wikipedia
