    Emergence and Early Disillusionment of a Field Era

    People with intellectual disabilities were mocked, observed, and mistreated. However, Jean-Marc Itard changed the idea of what an intellectual disability meant. He used systematic instruction on a boy that he found in the wild to correct his behavior and teach him skills. Others followed suit and helped to create instructional needs for special education.

    Jean-Marc Itard found a boy named Victor who he trained for several years. Victor most likely suffered from a disability of some sort as he was described as ‘savage and wild’.
