The People Who Prepared This
Lecture
Harry Peery
Alan Castle
Carl Sagan was a professor of
astronomy and astrochemistry at
Cornell University.
He wrote more than 600 scientific
articles, scripted and narrated a
popular astronomy program (
Cosmos,
A Personal Voyage
) which explained
the cosmos to more than 600 million
people in 60 countries. He wrote
books, his last being turned into a
movie,
Contact
, staring Jodie Foster,
which was finished after his death and
was dedicated to him.
He was also a believer and seeker of
extraterrestrial life and as such, was
threatened with death by several
groups. He was forced to travel with
bodyguards – even when lecturing in
his class at Cornell.
