David Thomas (1794-1882) was a Pennsylvania iron manufacturer who introduced into the United States the use of anthracite coal in the manufacture of pig iron. The papers consist of typed transcripts twelve letters, the bulk of which were sent by David Thomas to his niece, Jane Harris Bowen, and nephew, David Harris, in Wales. The letters deal primarily with family news, but Thomas also writes about general business conditions, the level of prices and wages and the Civil War.
