Chapter 5 History of intellectual disabilities

This chapter traces the history of intellectual disabilities by exploring significant historical periods and personalities who impacted the disability field and specifically the area of intellectual disability. Like other documented histories, the purpose of this chapter is to instruct and inform readers about the historical underpinnings of the labels, practices, and programs related to intellectual disability that are in effect today. While this chapter is not intended to be prescriptive in how the information presented here is to be interpreted, we are acutely aware that historical accounts are often interpreted based upon contemporary ideologies, knowledge, and practices. As such, as a historical account, this chapter is no exception. Current belief and practices about intellectual disabilities indeed influence the choices that, we as the chapter authors, made about the relative importance of the events that we select to highlight in this chapter. Nonetheless, this account reflects the events and personalities who, in our estimation, transformed and/or advanced the field of intellectual disability. We open with a brief prologue of the representations of the intellectual disability in popular culture and its potential impact on perceptions of persons with intellectual disability.
