S. Shoemaker and D. H. Levy at Palomar. Dava Sobel (b. 1947) is an author whose books have inspired a serious interest in the history of science among her millions of readers. Her most famous books---Longitude, Galileo's Daughter and The Planets---provide new insights into the most important historical issues in the evolution of scientific thought.
