US astronaut Neil Armstrong, the first man to walk on the moon, died at the age of 82 on Saturday after suffering complications from heart bypass surgery.
President Barack Obama said Armstrong “delivered a moment of human achievement that will be never be forgotten” and called him “one of the greatest American heroes of all time”.
It was a label that Armstrong himself was never comfortable with.
He shunned the limelight for years after that famous flight, refusing to give interviews or sign autographs.
Armstrong said he did not want to be “a living memorial.”
His pre-NASA career was spent serving in the US navy during the Korean War and as a test pilot for the military.
But the Apollo 11 commander will perhaps always be remembered for uttering one of the most famous quotes in the English language on that night of July 20th 1969:
“One small step for man, one giant leap for mankind.”
