Carl Sagan served as the David Duncan Professor of Astronomy
and Space Sciences and Director of the Laboratory for Planetary
Studies at Cornell University. He played a leading role in the
Mariner, Viking, Voyager, and Galileo spacecraft expeditions, for
which he received the NASA Medals for Exceptional Scientific
Achievement and (twice) for Distinguished Public Service.
His Emmy- and Peabody-winning television series, Cosmos,
became the most widely watched series in the history of American
public television. The accompanying book, also called
Cosmos, is one of the bestselling science books ever
published in the English language. Dr. Sagan received the Pulitzer
Prize, the Oersted Medal, and many other awards-including twenty
honorary degrees from American colleges and universities-for his
contributions to science, literature, education, and the
preservation of the environment. In their posthumous award to Dr.
Sagan of their highest honor, the National Science Foundation
declared that his "research transformed planetary science . . . his
gifts to mankind were infinite." Dr. Sagan died on December 20,
1996.
