Did you know Jackie Robinson was at Martin Luther King Jr.'s 'I Have a Dream' speech?

This post was originally published on Aug. 28, 2013, the 50^th anniversary of Martin Luther King Jr's historic "I Have a Dream" speech.

On August 28, 1963, Dr. Martin Luther King Jr. stood on the steps of the Lincoln Memorial and delivered his now famous "I Have a Dream" speech, calling for an equal America for all citizens.

Sixteen years earlier, Jackie Robinson made his Major League debut for the Brooklyn Dodgers, breaking the color barrier in baseball.

Robinson, who retired in 1956, joined the March on Washington and was at the National Mall the day Dr. King gave his address. The photo you see above shows Robinson with his son at that important moment in history.

While Robinson is remembered by most for his courage and leadership in the baseball world, he was also an impassioned civil rights leader outside it -- both before and after his baseball career.

His presence at the March, and his audience for King's words, help to illuminate the richness of Robinson's legacy: someone whose fight against prejudice changed the landscape of sports, and who continued to push for that change far beyond the field.
