Established the Christian Science Publishing Society (1898) that continues to publish periodicals she started including:

2. The Christian Science Sentinel (1898)
3. The Herald of Christian Science (1903)

She and others credit her with the ability to heal instantaneously. Married three times, she took the name Mary Baker Glover from her first marriage. She was also known from her third marriage as Mary Baker Glover Eddy or Mary Baker G. Eddy. [Wikipedia]

Terrified of competition from within, Eddy excommunicated anyone who seemed to threaten her power. She permitted no sermons, commentary, or discussion and made her books the only source of church authority, allowing no changes in church procedure but those she made personally. Thus, no changes have been made since her death…but her religion continues to flourish today, as does The Christian Science Monitor. [Remember the Ladies, Kirsten Olsen]
