Elizabeth Cellier, commonly known as the "Popish Midwife" (c. 1668 – c. 1688), was a notable Catholic midwife in seventeenth-century England. She stood trial for treason in 1679 for her alleged part in the "Meal-Tub Plot" against the future King James II,[1] but was eventually freed. Cellier was later imprisoned for allegations made in her 1680 work Malice Defeated, in which she recounted the events of the alleged conspiracy against the future King. She later became a pamphleteer and advocated for advancements in the field of midwifery. Cellier published A Scheme for the Foundation of a Royal Hospital in 1687, where she outlined plans for a hospital and a college for instructions in midwifery, as well as proposing that midwives of London should enter into a corporation and use their fees to establish parish houses where any woman could give birth.[2] Cellier resided in London, England until her death.
