Mary Baker Eddy The Years Of Trial By Robert Peel

Mary Baker Eddy: The Years of Trial is a landmark biography written by Robert Peel and first published in 1971 by Holt, Rinehart and Winston. It serves as the second volume in Peel's definitive three-part biographical trilogy documenting the life of Mary Baker Eddy, the founder of the Christian Science church. 

The biography chronicles a crucial 15-year window from 1876 to 1891. It opens immediately following the 1875 publication of the first edition of Eddy's foundational textbook, Science and Health, and follows her trajectory up to the landmark 50th edition in 1891. This era represents the "crucial period of trial and error" where Eddy transitioned from the little-known leader of a small New England group into an influential figure heading a rapidly expanding global religious movement.
