Amelia Elizabeth Dyer (born Hobley; 1836 – 10 June 1896) was an English serial killer who murdered infants in her care over a thirty-year period during the Victorian period of the United Kingdom. Trained as a nurse and widowed in 1869, Dyer turned to baby farming—the practice of adopting unwanted infants in exchange for money—to support herself. She initially cared for the children legitimately, in addition to having two of her own, but whether intentionally or not a number of them died in her care, leading to a conviction for neglect and six months' hard labour. She then began directly murdering children she "adopted", strangling at least some of them, and disposing of the bodies to avoid attention. Mentally unstable, she was committed to several mental asylums throughout her life, despite suspicions of feigning, and survived at least one serious suicide attempt.
