‘He Had Transformed’: What It Was Like to Watch Martin Luther King Jr. Give the ‘I Have Dream’ Speech

Tuesday marks 55 years since the Rev. Martin Luther King Jr. delivered his iconic "I Have a Dream" speech to the crowd that had gathered around the Lincoln Memorial for the Aug. 28, 1963, March on Washington.

While planning for the event had been going on for years before that day, and copies of the speech drafts and notes show that King had been working on what to say for weeks, many may not realize that the most famous lines were not planned at all.
