Chickering Hall, Boston, In an era when lectures and sermons were major media for addressing the public, Mrs. Eddy was a notable public speaker. In the late 1870s and 1880s in Lynn and in Boston, her periodic parlor talks gave way to regular addresses and sermons in ever-larger rented halls.
Twice she lectured to overflow audiences in Chicago auditoriums, and in 1889 she addressed over 1,000 at Steinway Hall in New York City.
As late as 1898, nearing her eightieth year, she preached at Christian Science Hall in Concord, New Hampshire, to a packed house which included several newspaper reporters.
