Emmanuel-Augustin-Dieudonné-Joseph, comte de Las Cases (June 21, 1766 - May 15, 1842) was a French historian and atlas maker. Born at the family's castle near Revel in Languedoc, Las Cases was educated at military schools in Vendôme and Paris. He then entered the navy where he saw action during the years 1781-82. He was forced to flee France during the French Revolution, and spent several years in Germany and England. He took part in the Quiberon Expedition in 1795 (an invasion of France on the Quiberon peninsula by émigré ,counter-revolutionary troops in support of the Vendée Revolt) that was soundly defeated by the Republican army. Las Cases was one of the few to return to London alive. In 1801 he published the first edition of his Atlas Historique under the pseudonym A. Lesage. Upon his return to France after the Peace of Amiens in 1802, Las Cases published the first French edition of his atlas in 1803-1804 called the Atlas historique, généalogique, chronologique et géographique de A. Lesage. Las Casas returned to France during the Consulate and, with other royalists, rallied to the side of Napoleon Bonaparte. Las Cases would support Napoleon throughout his reign, and was eventually made a chamberlain and then a count of the empire. After the first abdication in 1814, Las Cases again fled to England, but returned to Napoleon's side during the Hundred Days. After the defeat at Waterloo, Las Cases was the one who suggested Napoleon throw himself at the mercy of the British Empire and later accompanied him to Saint Helena. It was on Saint Helena where Las Cases acted as Napoleon's secretary, taking detailed notes of their conversations. These notes were then published in book form following Napoleon's death as Le Mémorial de Sainte-Hélène, which is remembered as a less-than-neutral account of Napoleon's time on Saint Helena.
