DEAD: ON THIS DATE
Carl Sagan (aged 62)
American astrophysicist, cosmologist, author and science educator
Carl Edward Sagan (November 9, 1934 –December 20, 1996) was an American astronomer, cosmologist, astrophysicist, astrobiologist, author, science popularizer, and science communicator in astronomy and other natural sciences. He is best known for his work as a science popularizer and communicator. His best known scientific contribution is research on extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by radiation. Sagan assembled the first physical messages sent into space: the Pioneer plaque and the Voyager Golden Record, universal messages that could potentially be understood by any extraterrestrial intelligence that might find them. Sagan argued the now accepted hypothesis that the high surface temperatures of Venus can be attributed to and calculated using the greenhouse effect.
DEATH: After suffering from myelodysplasia for two years, and receiving three bone marrow transplants from his sister, Carol, Sagan died of pneumonia at the age of 62, at the Fred Hutchinson Cancer Research Center in Seattle, Washington, in the early morning of December 20, 1996. Burial took place at Lakeview Cemetery in Ithaca, New York.
