From the Annals of Space –  In 1969,  Astronaut Neil Armstrong spoke the first words ever known to be uttered from a celestial body other than Earth.  At 3:18 CDT, Armstrong confirmed, “Houston, Tranquility Base here – the Eagle has landed.” He also became the first man to walk on the moon on later that same day. 

Old General Sam would be mighty amused to know that his name was the first word ever spoken from the Moon.
