- Abstract:
- Thomas Darlington Cope received his Ph.D. in Physics in 1915 at the University of Pennsylvania and spent his entire professional career at Penn. His prominence as a historian of science arose from his study of Charles Mason and Jeremiah Dixon, the English surveyors who were brought to America to help settle the border dispute between Maryland, Delaware, and Pennsylvania that resulted in the famous Mason-Dixon Line. The Thomas Darlington Cope Papers contains Cope's personal correspondence from 1912-1956, and his Mason and Dixon Line research.
