English midwife who established a corporation of midwives in London in 1687 and a foundling hospital. Cellier, who married Frenchman Peter Cellier and converted to Roman Catholicism, was falsely accused of treason in 1680, but defended herself and was acquitted. She wrote about the trial in a short but sensational publication entitled "Malice Defeated." She is believed to have been buried in Great Missenden Church, in Buckinghamshire, England.
