RESUMO
The early history of developmental language impairment in late 19th century Britain is considered through the critical examination of three papers appearing in 1891 by Hadden, Golding-Bird and Hale White, and Taylor. They represent innovative investigations of child language disorders whose themes and concerns are resonant today. The term 'idioglossia' was coined to identify this new impairment and reflected the belief by some that these children spoke an invented language. Rather than viewing these children as having some constitutional deficiency, these 19th century physicians were novel in insisting that children with language impairments merited extensive clinical investigation and treatment. Their case descriptions and the subsequent debates regarding classification and prognosis are reviewed. Further consideration is given to how these cases led to questioning the relation between language and speech and other aspects of child development and disorder. Reflection on the early sources of clinical categories provides a new perspective on our current formulations for variation in developmental language trajectories.

Childhood language disorders have been known and studied at least as far back as the early nineteenth century. The results of the early investigations, however, have essentially been forgotten. The aim of this article is to recall the investigators of the nineteenth century and their findings. Throughout most of that period efforts were directed simply at establishing the existence of mutism without deafness or "idiocy." In the last two decades an "information explosion" took place, authored by a small group of German-speaking physicians. On the basis of their clinical observations they described the disorders, offered theories on their nature and etiology, and devised therapy programs. These findings and theoretical constructions are presented, along with information on the probable sources of the authors' ideas. Although resemblances to modern concepts are often striking, it seems unlikely that the earlier work is the source of the more recent ones.
