Anna B. White Baker (b. Bradley) (1848-1931) was born in Pennsylvania and died in Newton, Massachusetts. She was raised as a Quaker and was teaching at a Quaker school in Philadelphia, Pennsylvania, when she met her first husband, Barclay White Jr. They married in Burlington, New Jersey, in 1877 and moved to Nebraska. Barclay died within the first few months of their marriage, and Baker returned to her parents' home in Coatesville, Pennsylvania, for the birth of their daughter, Rebecca M. White. In 1889, she married her second husband, Alfred E. Baker, a homeopathic physician, in Chester, Pennsylvania. The family lived on a farm in East Bradford, Pennsylvania, in the early 1890s. The Bakers were first introduced to Christian Science through Alfred's aunt, Dr. Rachel T. Speakman, who had been a physician before becoming a Christian Scientist in the late 1890s. In 1896, they had Primary class instruction with Flavia Stickney Knapp, a student of Mary Baker Eddy. Soon after, the couple moved to Boston, Massachusetts, to practice and teach Christian Science. They became students of Eddy, attending her Normal class in November 1898. Baker joined The First Church of Christ, Scientist, in Boston, Massachusetts, on November 1, 1898, and she was elected a First Member of the church in February 1899. Eddy was impressed with the Bakers and asked them to come to Concord, New Hampshire, in 1899. She asked Alfred to serve as a practitioner and teach classes there, while Anna served on and off on Eddy's staff at her Pleasant View household from 1899 through 1902. In 1902, the Bakers moved to Brookline, Massachusetts, and continued their Christian Science practice. They moved to Philadelphia in 1906 and returned to Massachusetts in the 1910s. By 1920, they were living in the village of Auburndale in Newton, Massachusetts. Baker was listed in the directory of The Christian Science Journal as a Christian Science practitioner in Concord from 1899-1901, Brookline from 1902-1903, Boston from 1904-1905, Philadelphia from 1906-1912, Auburndale from 1917-1921, and as a teacher there from 1922-1927. She wrote her reminiscences after Eddy's passing, assembling them from diaries, letters, and notes that she kept throughout her life. Titled "Happy Memories of Mary Baker Eddy," her reminiscence was published in We Knew Mary Baker Eddy, Volume 2.
