On July 20, 1969, the world watched as American astronauts Neil Armstrong, Edwin "Buzz" Aldrin and Michael Collins reached the surface of the moon. Those on earth saw the grainy image of Armstrong placing his feet on the moon's surface as he uttered his famous words — and the rest is history. In August of that same year, the "Moon Men" visited Chicago for a parade that weaved through the Loop and attracted about 2 million people.
