The Museum contains documents pertaining to her life and the lives of Christian Scientists who assisted her in establishing this worldwide religion. 
Mary Baker Eddy (1821 - 1910) was born near Concord, New Hampshire, and did most of her work in establishing Christian Science in Lynn, Boston, and Chestnut Hill, Massachusetts, and in Concord, New Hampshire.

Longyear Museum was founded by philanthropist Mary Beecher Longyear (1851 - 1931) to provide future generations with documentary evidence and facts about Mrs. Eddy and the early history of the Christian Science religion.

In 1937, the Museum opened in Mrs. Longyear’s former home in Brookline, Massachusetts.

The Museum moved to its present location in nearby Chestnut Hill in 1999; the new exhibit halls were opened to the public in 2001.
