The commander of Apollo 11, Neil Armstrong landed on the moon on July 20, 1969.  He was a "reluctant American hero", his family said they were heartbroken and noted that the space pioneer had "served his nation proudly, as a navy fighter pilot, test pilot, and astronaut".  "While we mourn the loss of a very good man, we also celebrate his remarkable life and hope that it serves as an example to young people around the world to work hard to make their dreams come true, to be willing to explore and push the limits, and to selflessly serve a cause greater than themselves," they said in the statement.
