Otto Louis-Guillaume (1754-1817) was a French diplomat who served as minister to the United States in 1779. He was secretary of the French Legation in America in 1782, and returned to France three years later. In Europe he enjoyed a successful career as a diplomat, signing on behalf of Napoleon the Treaty of Amiens in 1802. This treaty achieved fourteen months of peace in Europe during the French Revolution and the Napoleonic Wars.
