Collection Overview

Collection Description & Creator Information

Scope and Contents

Consists of 19 letters, dating from October 19, 1789 to October 10, 1791, from Louis-Guillaume Otto, comte de Mosloy, to fellow French diplomat Eléonore-François-Elie, marquis de Moustier (1751-1817). Moustier was French ambassador to the United States from 1787 to 1789 and then moved on to Berlin as the French Minister Plenipotentiary in 1790.

The 15 letters written between October 29, 1789 and October 13, 1790 were from New York; 4 letters written between March 8 and October 10, 1791 were from Philadelphia. Some of the letters are numbered. Also included is a 10-page letter with the title "Bulletin," dated January 18, 1790, which was likely intended for publication.

Otto's letters report on contemporary American affairs and include many references to American political leaders with whom Otto had established close ties, such as George Washington, Thomas Jefferson, Alexander Hamilton, John Adams, Benjamin Franklin, Robert Morris, Gouverneur Morris, and Colonel William Duer.

Kept with the letters is the 19th-century calf gilt slip-case in which they were formerly housed, with the spine title, "L. G. OTTO / LETTR. / AUTOGR."
