Jacqueline Pascal (October 4 1625-October 4 1661), sister of Blaise Pascal, was born at Clermont-Ferrand, Auvergne, France. She was a prodigy, composing verses when only eight years old, and a five-act comedy at eleven. In 1646 the influence of her brother converted her to Jansenism. In 1652, she took the veil, despite the strong opposition of her brother, and subsequently was largely instrumental in the latter's own final conversion. Wikipedia
