Mary Baker Eddy: a manipulative, mad woman who founded a cult which perverted the faith of true believers and distracted those involved in searching for spiritual truth.
The Christian Science movement is still current and should be avoided like the plague.
Christian Science is based on "metaphysical science." Its major teachings
include the belief that spiritual reality is the only reality and all else is
illusion or error. In contrast to conventional Christian theology, Christian
Science rejects both the common Christian views of the atonement and the concept
of Hell as a place of eternal punishment. Christian Science holds that sickness
and disease are the result of false education, fear, ignorance, or sin, and
should be healed through prayer or introspection.A number of preventable deaths
have occurred among Christian Scientists and their children because of a lack of
conventional medical treatment and avoidance of vaccination. (Wikipedia)
