Kraepelin noted the dissemination of his new disease concept when in 1899 he enumerated the term's appearance in almost twenty articles in the German-language medical press. In the early years of the twentieth century the twin pillars of the Kraepelinian dichotomy, dementia praecox and manic depressive psychosis, were assiduously adopted in clinical and research contexts among the Germanic psychiatric community. German-language psychiatric concepts were always introduced much faster in America (than, say, Britain) where émigré German, Swiss and Austrian physicians essentially created American psychiatry. Swiss-émigré Adolf Meyer (1866–1950), arguably the most influential psychiatrist in America for the first half of the 20th century, published the first critique of dementia praecox in an 1896 book review of the 5th edition of Kraepelin's textbook. But it was not until 1900 and 1901 that the first three American publications regarding dementia praecox appeared, one of which was a translation of a few sections of Kraepelin's 6th edition of 1899 on dementia praecox.
