The Pfizer Award
was established in 1958 through the generosity of Pfizer, Inc., a diversified research-based company. The award consists of a medal and $2,500. This prize is awarded in recognition of an outstanding book dealing with the history of science. The book must be published in English during a period of three calendar years immediately preceding the year of competition. Edited volumes, as well as works with more than 2 authors, are not eligible. A multi-volume work by one or two authors may be nominated only after the publication of all the volumes. The Pfizer Prize may not be split between two books. The prize committee may consider books where medicine or technology is a central theme. However, both the Society for the History of Technology and the American Association for the History of Medicine award their own prizes and while strict separation of fields is not always possible or desirable, the Pfizer Award should be given to a book that is principally a history of science.
