Nearly seventy-five years ago, Donald Triplett of Forest, Mississippi became the first child diagnosed with autism. Beginning with his family's odyssey, In a Different Key tells the extraordinary story of this often misunderstood condition, and of the civil rights battles waged by the families of those who have it. Unfolding over decades, it is a beautifully rendered history of ordinary people determined to secure a place in the world for those with autism--by liberating children from dank institutions, campaigning for their right to go to school, challenging expert opinion on what it means to have autism, and persuading society to accept those who are different. It is the story of women like Ruth Sullivan, who rebelled against a medical establishment that blamed cold and rejecting "refrigerator mothers" for causing autism; and of fathers who pushed scientists to dig harder for treatments.
