The Dutilh & Wachsmuth collection is made up of approximately 160 letters and documents, 250 financial records, and 12 printed items related to the Philadelphia merchant company in the late 18th and early 19th centuries. Many items concern George Louis Stockar, a Swiss merchant living in La Rochelle, France.
The Correspondence and documents series contains approximately 160 items, including the incoming business correspondence of Dutilh & Wachsmuth. The firm frequently dealt with food and lumber, and traded with merchants in French port cities, such as Bordeaux and Marseille, and in Philadelphia. Correspondents occasionally reported on the wheat trade and sometimes commented on political events in France and Haiti. Within a group of 14 items related to Captain Jean Christopher Sicard is a chart concerning a shipment of cargo between Marseille and New York, transported by Captain Sicard and signed on May 28, 1793. A group of approximately 10 items dating from 1781 to 1785 relate to George Louis Stockar, and include papers about his establishment of a business in La Rochelle, France. One letter, dated May 27, 1790, is written in German by M. Lang to John Godfried Wachsmuth, detailing a trip from Philadelphia to Fort Pitt. Lang notes the death of a pet dog, being injured by a captive bear, conflict with German settlers, and being persuaded by a wealthy family travelling with slaves to serve as their guide and protector against Native American attacks as they descended to Kentucky.
The Financial papers consist of approximately 250 items, such as account books, loose accounts, receipts, and other types of financial records, mostly related to the Dutilh & Wachsmuth firm's financial affairs. Some of the accounts pertain to John Dutilh's personal finances.
Among the collection's 12 Printed Items are a declaration by King Louis XVI, issued on June 20, 1784, to the citizens of the Canton of Schaffhausen, and a public letter to the citizens of the Pays-Bas region (May 26, 1795).
