Alexander Duer Irving Jr. (1873-1941) was assigned as a junior naval aide to President Woodrow Wilson (1856-1924) on his trip to the Paris Peace Conference, primarily because of his knowledge of French. He served with the rank of lieutenant under Wilson's personal physician, Admiral Cary T. Grayson (1878-1938). The papers record details of protocol at the signing of the Treaty of Versailles. Irving gives much social detail of formal affairs attended and the intricacies of protocol. He reports background information on French labor unrest, the high cost of living, and the fear of Bolshevist infiltration.
