Collect 'em all!
Carl Edward Sagan
(Nov 9, 1934 – Dec 20, 1996)
Birthplace: (Brookly, NY, United States)
Culture-shaping contribution: Made astronomy, astrophysics and cosmology appealing to the masses via his unequalled educational television series Cosmos, based on his book of the same name. Is also responsible for the Baloney Detection Kit, an invaluable guide to testing arguments.
Fun fact: Wrote an essay on the benefits of smoking cannabis for a 1971 book Marihuana Reconsidered. Sagan, using the pseudonym "Mr. X", claimed his use of the drug had not only enhanced sensual and intellectual experiences but had also inspired some of his works. Mr. X's true identity was revealed shortly after Sagan's death.
