The dissemination of Kraepelin's disease concept to the Anglophone world was facilitated in 1902 when Ross Diefendorf, a lecturer in psychiatry at Yale, published an adapted version of the sixth edition of the "Lehrbuch der Psychiatrie". This was republished in 1904 and with a new version, based on the seventh edition of Kraepelin's "Lehrbuch" appearing in 1907 and reissued in 1912. Both dementia praecox (in its three classic forms) and "manic-depressive psychosis" gained wider popularity in the larger institutions in the eastern United States after being included in the official nomenclature of diseases and conditions for record-keeping at Bellevue Hospital in New York City in 1903. The term lived on due to its promotion in the publications of the National Committee on Mental Hygiene (founded in 1909) and the Eugenics Records Office (1910). But perhaps the most important reason for the longevity of Kraepelin's term was its inclusion in 1918 as an official diagnostic category in the uniform system adopted for comparative statistical record-keeping in all American mental institutions, "The Statistical Manual for the Use of Institutions for the Insane". Its many revisions served as the official diagnostic classification scheme in America until 1952 when the first edition of the "Diagnostic and Statistical Manual: Mental Disorders", or DSM-I, appeared. Dementia praecox disappeared from official psychiatry with the publication of DSM-I, replaced by the Bleuler/Meyer hybridization, "schizophrenic reaction".
