This history of autism and the people who brought it to public attention - they were mostly savvy parents of children "on the spectrum" as it is now called - is a combination of heartbreaking and hopeful. There have been lots of missteps along the way, particularly the current tendency for people with the condition to angrily condemn those who are looking for a cause and a cure.
