This is the story of how Wilson’s disease, a previously rare and fatal inherited disease, was conquered by a series of individual discoveries, leading to highly effective treatments. It also describes the difficulties which had to be overcome to achieve this in the face of government and institutional bureaucracy. It should be of interest to those involved in medical research, to doctors interested in rare diseases and to the lay public who want to know how medical advances are made. Technical details are kept to a minimum so that an understanding of medical and technical terms is not needed. The book should prove to be a very useful resource for researchers studying Wilson’s disease and its history in medicine.
