The face of intellectual disability services has changed through time. In this article, we are going to explore some of the key thinkers of intellectual disability in history, and how they influenced perspectives on intellectual disability.

Throughout history, people with intellectual disability were stigmatised, feared, persecuted and frequently mistreated. It wasn’t until the mid to late 19th century that a more positive approach to people with intellectual disability began. It was around this time that institutions were established for people with intellectual disability.

19th Century

Led by influential individuals such as Itard, Esquirol, Guggenbuhl, Howe, and Seguin, the concept of care and education provision for people with intellectual disability began.

This emerged from the school of thought that individuals with an intellectual disability could be taught.
JM Itard, a French physician, was probably the most influential of all and is famous for his work with Victor, the wild boy of Aveyron.

Victor was found in the Caune Woods in France, naked and unable to speak. Itard tried to teach the boy how to speak and read, and after five years, Victor was able to understand some written words.
People with intellectual disability were frequently referred to as idiots, feebleminded or retarded. This type of labelling and putting a name on people’s condition is a debate that still permeates discussions today. Only quite recently, the term mental retardation used in the United States, was changed to intellectual and developmental disabilities.

Early 20th Century: The rise of custodial institutions

Institutional care continued from Itard’s time, however towards the end of the 19th century and the beginning of the 20th century, custodial institutions became popular. For example, lunatic asylums. They gained a strong foothold in care provision for people with intellectual disability.

Many countries during this time were poor economically and social conditions were often difficult. This also reinforced fear and stereotyping by the general public, and had an impact on educating people with intellectual disability. Instead of educating people so they could live well in the community, education within custodial institutions was often used to sustain the institute, rather than teach new skills. People with intellectual disability became more segregated from society.

Mid 20th Century: Dr Wolfensberger and his principle of normalisation

This type of care provision continued up to the mid-20th century, until the pioneering work of Dr Wolf Wolfensberger. A major shift in the school of thought towards the education and care of people with intellectual disability happened. The emergence of Dr Wolfensberger’s ‘Principle of Normalisation’ focused on improving the lives of people with intellectual disability.
The principle emphasises the concept of making available patterns of life and conditions of everyday living which are as close as possible to the regular circumstances and ways of life or society.
Dr Wolfensberger actively worked towards advocating for value in the lives of people with intellectual disability, and strove against society’s readiness to marginalise and devalue these individuals. He was also the originator and foremost propagator of Citizen Advocacy and Social Role Valorisation. This focused on people speaking out and speaking up for those more vulnerable in society, in order to recognise the value of a vulnerable person.

The end of segregated living?

One area advocated for was to improve the living circumstances of people with intellectual disability. This included ending segregated living in places such as institutions. This has been slow to change and many countries continue to struggle with providing quality services in a meaningful and equitable way for people with intellectual disability.

Today: Improvements in health and social care

Due to the influence of such movements, the health and social care provision for people with intellectual disability improved and, as a direct consequence, so too did their overall health and wellbeing. People with intellectual disability are now enjoying a much longer lifespan, especially in the last decade or so.
However, as this is the first time in history people with intellectual disability are living into old age, there is very little understanding of their ageing experience, their thoughts on ageing and exactly how they age.

As you will discover further into the course, their health is compromised, they do experience older age conditions much younger and, despite a marked increase in longevity, their mortality rate continues to be, on average, 20 years younger than people from the non-disabled population.

In your experience:

  • Do you think the health care services and conditions for people with intellectual disability could be improved further through total integration into community living, or do you think there is still need for specialist services?
