John William "Jack" King (February 12, 1931 – June 11, 2015) was a Chief of Public Information and Public Affairs Officer for NASA. He is best known for his work as Kennedy Space Center Chief of Public Information during projects Mercury, Gemini and Apollo. As part of this role, he provided public announcements and commentary for several of the mission launches. He is best known for his announcement of the Apollo 11 launch, which earned him the nickname "Voice of Apollo". The iconic commentary from that launch has been reused in songs and advertisements, including the song "Tout Va Bien" by the Japanese group Pizzicato Five and was included in a 2011 collection of NASA sounds from historic spaceflights that can be used as ringtones.
