The founder of Christian Science. Sickly for much of her life, she sought treatment from many different healers, including a mesmerist and magnetic healer named Phineas Quimby. This experience inspired Eddy to write a book titled Science and Health with Key to the Scriptures, in which she equated God with the mind and argued that sickness is spiritual, not material. Eddy believed that mental techniques could be used not only for healing, but also to harm people, which she termed 'malicious animal magnetism.' She founded the Christian Science Monitor and laid out guidelines for her church in the Manual of the Mother Church, which established Christian Science reading rooms.
