The James Dinwiddie (1746-1815) papers were donated to the Dalhousie University Archives in 1999. A Scottish scientist and lecturer, the bulk of his papers consist of his scientific observations, experiments, and lecture notes, with dates ranging from 1767 to 1815. His fields of research included history, physics, chemistry, engineering, military tactics, and many other diverse topics. Of particular interest is Dr. Dinwiddie's observations and journal entries from his time abroad. As part of the first major embassy to the emperor of China, Dinwiddie was responsible for demonstrating European technology to the imperial court. Later he would spend many years in India, where he continued his lectures and scientific observations.
