Sienkiewicz-Mercer was born in Northampton, Massachusetts. She was a healthy baby, but was afflicted with a severe bout of encephalitis at the age of five weeks. At thirteen months, she was diagnosed with cerebral palsy resulting from the encephalitis. Her control over her entire body, except for her face and digestive system, was severely impaired; though not completely paralyzed, she could not care for herself or communicate through speech as most people know it. Due to her inability to communicate normally, she was diagnosed as an imbecile at the age of five. She lived mostly with her family until age eleven, with some brief stays in rehabilitation centers invariably terminated by her family's poor financial situation. As she approached her teens, it became increasingly difficult for her mother and family to care for her. Her parents decided to send her to the Belchertown State School, an institution for the mentally and physically disabled. There, like many of the institution's patients, she was severely mistreated. She spent most of the next eight years lying inbed in a ward of schizophrenics, ministered to by overworked attendants who often force-fed her and assumed that as an imbecile she had no awareness of the world around her. A staff turnover in 1967 began to change things, as Sienkiewicz-Mercer learned to communicate with some of the new attendants and formed close friendships with them. Several attempts by the school at establishing a physical therapy and education program resulted in the development of a word board for her, providing her with a robust method of communication for the first time. In 1973, the massive building in which the mental wards were housed was renovated, and she was moved to a small temporary building with nineteen other high-functioning patients. The attendants there were friendly and the atmosphere far less oppressive than the wards; the patients were given greater liberty, to the extent that some were allowed to drink alcohol. With the support of many friends, she and some fellow patients left the State School and moved into their own apartment in 1978. One of these ex-patients, Norman Mercer, she married. The year after, her autobiography was published to media attention and critical acclaim. After her departure from Belchertown, she became a disability rights activist, giving "speeches" in cities across America. Her efforts may have contributed to the closure of Belchertown State School in 1992.
