This prize should not be confused with the Watson Davis Award from the Association for Information Science and Technology. The Watson Davis and Helen Miles Davis Prize of the History of Science Society is awarded yearly for a book published, during the past three years, on the history of science for a wide public. The book should "introduce an entire field, a chronological period, a national tradition, or the work of a noteworthy individual." The book can be written by multiple authors or editors and is required to be written in English and suitable for an audience including undergraduates and readers without specialized, technical knowledge. The author (or collective author) receives 1,000 U.S. dollars and a certificate. The prize, established in 1985, is named in honor of Watson Davis and Helen Miles Davis who were science popularizers in the USA. Source: Wikipedia (en)
