Toward a Photographic Rhetoric of Nineteenth-Century Scientific and Technical Texts

Abstract

Beginning in the 1850s, authors of American and British scientific and technical publications began to integrate photographs into their texts. These chemical and photo-mechanically reproduced images often functioned as the basis for carefully defined claims for truth. In the natural sciences, in microscopy, in medicine, in the emerging studies of psychology and the social sciences, and in the dissemination and promotion of technological accomplishments, the verity of early published photographs led authors to claim that an image could be equal to its referent in nature, or even exceed its referent when conveying scientific and technical information. This article presents a technological, cultural, and rhetorical history of published photographs based upon twenty-three images selected from a review of forty photographically illustrated texts published between 1854 and 1900.
