I. Du Pont Denemours & CoHISTORY: E. I. Du Pont was born in France and moved to America in 1792 or 1793. He started the Bridgeport Standard Du Pont Co (in everything I've read) in 1802. Since the plate says 1793-1802, it may have been that he is marking when he came to America. E. I. Du Pont Denemours died in 1834. In 1939 Dupont merged with Dow Chemicals, and to this day retain much of the Du Pont Company.Thank you so much for looking and please feel free to ask any questions.
