This compilation of biographical sketches of 400 “leaders” of American “science” could become a favorite resource for students at the secondary school level. Easy to navigate, with useful and quick summary information, it should appeal to those accustomed to instant feedback in a variety of predigested forms. Included in the list are 380 men and 20 women, not more than a quarter of whom started their careers before 1900. The earliest is Benjamin Banneker; the latest, Jason Lanier. Various features make (...) it easy and absorbing to search or browse the disk. One can search by text, attribute, or subject, with the results displayed for further actions. For example, one can search by some or all of the following “attributes”: occupation, birth and/or death date, sex, ethnicity, and birthplace. One can then view the results along a “timeline,” which is unfortunately anchored mostly by political events or wars rather than great events in science and technology. “Birthplace” leads to one of 85 basic, colored, easy‐to‐read “maps” of states and countries of origin. “Notebook” permits cutting, pasting, and annotating selected text from the disk or adding one's own to compile an original document. “Ethnicity” yields 375 Caucasians, 14 Afro‐Americans, 11 Asians, and 2 Hispanics. Most biographical sketches come with a photograph or portrait of the scientist and have bibliographical references for further information. Highlighted text links to other biographies, geographical locations, or a glossary of 294 terms to help with unfamiliar terminology. There is a 71‐term “subject index,” and appropriate “help” is available. But there are shortcomings. Glossary explanations are limited, and it's not clear why some terms are included but others not. A relative lack of inclusion of specialized terms limits technical understanding, and hence the educational value of the CD. Although the sketches are described as “in‐depth profiles,” most are quite short and have few bibliographic references. References, dating to 1996, are a mixture of popular and scholarly articles, books, and websites; Asimov's Biographical Encyclopedia of Science and Technology seems to be cited more often than the Dictionary of Scientific Biography. Credits describe the author, Amanda de la Garza, as “a professional writer, web page designer, and editor,” further reinforcing the impression that this is not a scholarly work. A perennial problem with such compilations is who's included and who's excluded. The absence of explicit selection criteria, as in this case, only augments inevitable questions about bias and representativeness. No scientist before Banneker is listed, and a number of pre‐Revolutionary notables are omitted. Many eminent scientists from 1800 to 1860 are omitted. Ironically, O. C. Marsh is in, but E. D. Cope is out. Barry Commoner is the one environmental biologist, Rachel Carson the sole ecologist. Nearly 25 percent of the list are physicists, who, despite their acknowledged importance in science, make up less than 10 percent of the scientific community. Nobelists are well represented—and the Nobel Prize may be a major selection criterion for the twentieth‐century scientists on the list. There are 18 inventors, 1 promoter, 1 explorer, and 1 industrialist among the “scientists,” who also include 33 “medical” people, including 8 surgeons. It is clear from the list of occupations that the term “scientist” is broadly inclusive; the consequent blurring of common distinctions between science, engineering, medicine, and invention further raises questions about what it means to be a “leader of science.” It would have been useful to have more attributes included, thus making the sketches more uniform and comparable and the search combinations more varied. A complete and separate bibliography would have been useful. So, too, would have been a Mac version, especially given Apple's connection with education and its appeal to scientists and engineers. All in all, this disk is a good pilot project with obvious promise. Much still remains to be done to make it a reputable educational tool for higher education. At the moment, it's sadly too truncated for other than the most superficial college or university work. (shrink)
