Jean Adrien Antoine Jules Jusserand (1855-1932) was a French author and diplomat. He was the French ambassador to the United States during World War I. Born at Lyon, Jusserand entered the diplomatic service in 1876. Two years later, he became consul in London. After an interval spent in Tunis (Tunisia was at that time a French protectorate), he returned to London in 1887 as a member of the French Embassy. In 1890, he became French minister at Copenhagen. In 1902, he was transferred to Washington, where he remained until 1925. During the Polish-Soviet War, Jusserand took part in a diplomatic mission to the Second Polish Republic. He was a close student of English literature and produced some lucid and vivacious monographs on comparatively little-known subjects. His works include: English Wayfaring Life in the Middle Ages (1889), The English Novel in the Time of Shakespeare (1890), A Literary History of the English People (1895) and With Americans of Past and Present Days (1917).
