Who declared he had ' a dream' where all Americans would live as equals?

Dr. Martin Luther King Jr. declared he had "a dream" during his iconic speech at the March on Washington for Jobs and Freedom on August 28, 1963. In his speech, he envisioned a future where people would be judged by their character rather than the color of their skin, and where all Americans would live together in harmony and equality. This moment became a pivotal point in the American Civil Rights Movement.
