Alice M. Sibley (1865-1939) was born in Boston, Massachusetts, and died in Merrimack, New Hampshire. She was a student and close companion of Mary Baker Eddy's. In the summer of 1882, Sibley accompanied Mary Baker Eddy to Barton, Vermont, where Eddy spent a month following the death of her husband, Asa G. Eddy. Upon their return to Boston, Sibley enrolled in the Massachusetts Metaphysical College, studying with Eddy in August 1882. Her relationship with Mary Baker Eddy and Christian Science seems to have ended abruptly in 1883 at the insistence of Sibley's family.
