Carl Sagan’s enduring legacy will always be linked to his ability to convey the wonders of science to the general public and his skill to inspire a new generation of scientists. In Fact, Sagan made the front cover of Time Magazine (Monday October 20th, 1980) which dubbed him the “Showman of Science.” The cover story, entitled ‘The Cosmic Explainer’ by Frederic Golden contains a very good biographical sketch of Carl and appeared when his landmark documentary Cosmos graced our television screens some twenty seven years ago.
Another good source of biographical information was given in the A&E biography documentary that appeared shortly after his untimely death on December 20th, 1996. It is a very good portrayal of how a kid from Brooklyn made good and became something of a media superstar —“indeed, a supernova of sorts”. So for your perusal “Heeere's Carl, bringing you nothing less than the universe.”
