John William Draper

Born in England in 1811, John William Draper moved to the United States in the early 1830s and trained as a physician. He spent much of his career at New York University, where he worked as a professor of chemistry and became known for research that crossed medicine, science, and photography.

Draper is remembered as one of the early experimenters who showed what photography could do for science. He made important photographic studies, including early work on the human face and the Moon, and he wrote on chemistry, physiology, and natural philosophy in a way that reached both specialists and general readers.

Later, he became especially well known for historical works such as History of the Intellectual Development of Europe and History of the Conflict between Religion and Science. Those books helped shape public discussion far beyond his own century, making him notable not only as a scientist, but also as a writer whose ideas sparked lasting debate.
