Here is a link to Through a Mirror Darkly: Children with Disabilities in American Policy, 1912-1960. It’s an interesting presentation by Walter O. Schalick, III, MD, PhD about the history of policies (medical and political) pertaining to disabled children. This broadly historical, and entertaining, presentation would be a perfect compliment to the Julia Lathrop video that I linked to previously. Dr. Schalick opens with the Ashley X case study and then turns back the clock to the 19th century and charts forward to more or less present day, though his title only promises to cover to 1960.
This video would have been the perfect introduction to the course I taught on bioethics and disability a while back.
