Philippe Ariès (1914-1984) is one of the greatest historians of the twentieth century. Representative, together Michel Foucault, of what became known as the school of "new history", his work is difficult to classify, because it is in the boundaries of several of the humanities: history, anthropology, philosophy, ethnology, cultural studies. Ariès was a lonely and eccentric figure of the French academic world. He some notable books such as History of the French people and their attitudes toward life are from the eighteenth century, his famous work on the child and family life under the old regime, the man facing death and the celebrated history of private life which he wrote with Georges Duby.
