When did Mary Baker Eddy work with Phineas Quimby?

Mary Baker Eddy was associated with the mental healer Phineas Parkhurst Quimby from 1862 to 1865. During this period, she sought treatment from him and became a disciple, an experience that strengthened her belief in the mental nature of disease and encouraged her study of New Testament healing.1

While Quimby served as an important stimulus to her development, the relationship remains a subject of historical controversy. Eddy later denied that her discovery of Christian Science was influenced by him, and subsequent evaluations have noted that the religious teachings of Christian Science were essentially foreign to Quimby’s own thought.21
