Before women could participate directly in the creation of scientific knowledge, they worked privately as translators, illustrators, and authors of science books. In the early nineteenth century, Jane Marcet in Britain, and later Almira Lincoln Phelps in the U.S., recognized the need for experimental training of beginners and, to compensate for the lack of experiments, produced meaningful drawings for their textbooks. By using a fresh narrative, a pleasing style, and beautiful drawings of their own, they wrote chemistries for the beginners that were both instructional and entertaining. Engraved in the tradition of the nineteenth century illustration, Jane Marcets Conversations on Chemistry and Almira Lincoln Phelps Chemistry for Beginners, originally written for the education of women, were immensely successful and lasted longer than many of the more specialized contemporary works.  相似文献
