by Margaret W. Carruthers and Susan Clinton
New York: Franklin Watts, 2001. 144 pages.

Suitable for budding geologists in fifth through ninth grades, Pioneers of Geology engagingly presents the history of geology by concentrating on the life and works of six important geologists: James Hutton, Charles Lyell, G. K. Gilbert, Alfred Wegener, Harry Hess, and Gene Shoemaker (who not only discovered the comet Shoemaker–Levy 9, but also is widely considered the father of planetary geology). With black-and-white illustrations and photographs; a geological time scale and a diagram of the age and structure of the earth appear in appendices, along with a helpful glossary and a bibliography including references to internet resources.
