April 15, 1947 - Jackie Roosevelt Robinson became the first African American to play in a major league baseball game in the 20th century. His stepping onto Ebbets Field in a Brooklyn Dodgers uniform broke the “color line,” the segregation of professional teams.
The International League in 1887 began a wave of League-wide black exclusion, and it had been complete since 1899, when Bill Galloway became the last African-American player in white organized ball (Woodstock, Ontario).
Though hitless in three at-bats, Robinson started at first base, and the Dodgers beat the Boston Braves that day, 5-3.
"Jackie, we've got no army. There's virtually nobody on our side. No owners, no umpires, very few newspapermen. And I'm afraid that many fans will be hostile. We'll be in a tough position. We can win only if we can convince the world that I'm doing this because you're a great ballplayer, a fine gentleman."
"There was never a man in the game who could put mind and muscle together quicker and with better judgment than (Jackie) Robinson."
