Biography of Eugene Shoemaker, propounder of the "impact theory" of craters, and co-discoverer of Shoemaker-Levey 9, the Jupiter impacting comet of 1994
Clyde Tombaugh is one of the best-known astronomers — amateur or professional — of the last century. Although famous for his discovery of Pluto, Tombaugh left his mark on many areas of astronomical discovery, from comets to variable stars to superclusters of galaxies. David Levy’s biography of this planet hunter includes aspects of Tombaugh’s life that may surprise readers who know him only for finding the ninth planet. Based on interviews with Tombaugh and his colleagues, friends, and family, this book also draws on the scientific record to offer a thorough account of the life of one of astronomy’s most important figures.
