Carl Sagan. Born in 1934. Died in 1996. Arguably, Sagan was everyone’s favorite scientist, working diligently to popularize science and make it accessible to the masses. He contributed much to science and technology, and created the Pioneer plaque and the Voyager Golden Record, messages to extraterrestrial life should they come across Pioneer 10, Pioneer 11, or Voyager 1 and wish to know where these spacecrafts came from.
