In the early 1960s, Clara Park and her husband took their 3-year-old daughter, Jessy, to a specialist after noticing that she avoided connection with others. The psychiatrist diagnosed Jessy with autism and blamed Clara. Refusing to accept this, Clara decided to document her family's experiences. In 1967, she published The Siege, her groundbreaking memoir challenging the refrigerator mother theory. Dispelling many misconceptions, Marga Vicedo illuminates the story of how Clara Park and other parents fought against medical and popular attitudes toward autism.
