Ellen Sadler (15 May 1859 – after 1901), sometimes called The Sleeping Girl of Turville, was a resident of Turville, a small village in Buckinghamshire in the United Kingdom. In 1871, aged eleven, she purportedly fell asleep and did not wake for nine years.[1][2][3] The case attracted international attention from newspapers, medical professionals and the public.
Born to a large, impoverished family of farm workers, Ellen was sent to work as a nursemaid at the age of eleven. Soon afterwards, she began suffering periods of drowsiness and was referred to a local hospital. After four months, her condition was declared incurable, and she was sent home. Two days later, Ellen had a series of seizures and—her mother claimed—fell into a deep sleep from which she could not be roused.
Ellen became a tourist attraction for the village, and her family made considerable money from visitors' donations. As the years progressed with no sign of Ellen's waking, speculation grew that her illness was either a hoax or caused by her mother, an issue that was never resolved. In late 1880, soon after her mother's death, Ellen awoke. She later married and had at least five children.
