Dava Sobel (born June 15, 1947) is the author of Longitude, Galileo's Daughter, The Planets, and most recently A More Perfect Heaven: How Copernicus Revolutionized the Cosmos. A former staff science reporter for The New York Times, she has also written for numerous magazines, including Discover, Harvard Magazine, Smithsonian, and The New Yorker.
Her most unforgettable assignment at the Times required her to live 25 days as a research subject in the chronophysiology lab at Montefiore Hospital, where the boarded-up windows and specially trained technicians kept her from knowing whether it was day outside or night.
Her work has won recognition from the National Science Board, which gave her its 2001 Individual Public Service Award "for fostering awareness of science and technology among broad segments of the general public." She also received the 2004 Harrison Medal from the Worshipful Company of Clockmakers in England and the 2008 Klumpke-Roberts Award from the Astronomical Society of the Pacific for "increasing the public understanding and appreciation of astronomy."
A 1964 graduate of the Bronx High School of Science, she has taught several seminars in science writing at the university level, and looks forward to a two-year residency at Smith College beginning in fall 2013.
