The authors reflect on a hundred years of disability policy. In brief chapters, they trace how the concept of disability emerged and how its substantive meaning has continually evolved, based on historically significant dates and events. The book provides a historical overview as well as the opportunity to gain insight into topics such as eugenics, self-determination, dignity, and inclusion. The authors, Christian Mürner, a publicist and disability educator, and Udo Sierck, a long-time activist in the disability movement, shed light on the developments and changes that have influenced opportunities for participation and acceptance over the course of a century.
