The Beaumarchais papers primarily consist of 106 incoming and outgoing letters of Pierre-Augustin Caron de Beaumarchais; his wife, Marie-Thérèse-Emilie Willer-Mawlar; and his daughter, Eugénie Beaumarchais Delarue. The collection also includes a letter book of Pierre Beaumarchais and two documents.
The Correspondence series is comprised of 35 letters by Pierre Beaumarchais, 65 by Marie, and 6 by Eugénie. Pierre addressed the bulk of his letters to Monsieur Airain, an attorney from Tours, France, and informed him of business affairs and travel plans. The series also includes a letter from Pierre Beaumarchais to Monsieur DeFraney, in which he discusses developments in the American Revolution (March 18, 1779). This letter bears a watermark of King Louis XVI's Grand Royal Coat of Arms. Other correspondence also includes personal letters by his family, who discussed their health and social life. The letter book is made up of correspondence between Pierre Beaumarchais and his friend, "Citizen Perregaut," discussing his travels and the life of his family; a contemporary list of documents related to his arrest and subsequent imprisonment (p. 17); and items detailing his interactions with various members of the French government. One letter, for example, regards a financial advance received from the Committee of the Republic (p. 19).
The Documents series contains a power of attorney, granted by Pierre Beaumarchais to Jean Auguste Marie Chevaillé (July 29, 1787), as well as a monetary allowance granted by Beaumarchais pertaining to Monsieur Comte [D'artois] (January 2, 1788).
