Childhood amnesia was first formally reported by psychologist Caroline Miles in her article "A study of individual psychology", in 1895 by the American Journal of Psychology.[10] Five years later, Henri and Henri published a survey showing that most respondents' earliest recollections occurred from the age of two to four.[11] In 1904 G. Stanley Hall noted the phenomenon in his book, Adolescence: Its Psychology and Its Relations to Physiology, Anthropology, Sociology, Sex, Crime, Religion and Education.[12] In 1910, Sigmund Freud offered one of the most famous and controversial descriptions and explanations of childhood amnesia.
