Carl Edward Sagan (1934–96) was an American astronomer and author of numerous books of popular science.
Born in New York City, Sagan studied at universities of Chicago and Berkeley, worked at Harvard then moved to Cornell, becoming a professor of astronomy and space science in 1970. He studied the surfaces and the atmospheres of the major planets, conducted experiments on the origins of life on earth, and argued about the environmental consequences of nuclear war.
Sagan was controversial in scientific, political, and religious circles for his views on extraterrestrial intelligence, nuclear weapons, and religion. He wrote several popular books explaining developments in astronomy, biology, and psychology. His notable works include Cosmic Connection (1973,) The Dragons of Eden (1977; Pulitzer,) and Broca’s Brain (1979.)
Sagan was president of the Planetary Society 1979–96 and a strong proponent of SeTI, the search for extraterrestrial intelligence. Contact (1985,) Sagan’s novel about the search for alien life, was made into a popular 1997 film.
