Say's Creative Process

Though New Harmony was located on the rough frontier of the young United States, the community had a printing press. Using this press, Thomas produced six volumes of the first comprehensive publication on American mollusks, American Conchology, or Descriptions of the Shells of North America: Illustrated by Coloured Figures From Original Drawings Executed from Nature (Parts 1-6, New Harmony, 1830-34; Part 7, Philadelphia, 1836). 

Lucy collaborated with her husband by illustrating his book, drawing 66 of the 68 illustrations. She and a handful of assistants also hand colored the printed illustrations. Of the 66, the APS Library has 47 drawings and printed proofs. All images included in this online exhibition are from the APS collection.

The drawings had to be exact in every detail, including form and color, and Lucy excelled at this. Photography was not regularly used in scientific research to document the living world until the 1860s or later. Before then, artists were needed to record natural specimens. Naturalists had to be both scientists and master draftsmen, precisely depicting what they observed.
