First-person accounts, or memoirs, have held an important role in the development of American psychiatry. Early editions of the American Journal of Insanity published letters from patients to asylum superintendents, although Isaac Ray warned Dorothea Dix in 1864 to be cautious about the reliability of such letters. Nineteenth-century accounts, such as those by Elizabeth Packard, highlighted perceived abuses of psychiatry and contributed to commitment law revisions. Clifford Beers' 1908 account, A Mind That Found Itself, incited the founding of the mental hygiene movement.
