Ebenezer J. Foster Eddy (1847-1930) was a homeopathic physician from Vermont. He attended one of Mary Baker Eddy's Primary classes in 1887, and was again taught by her in a Normal class in 1888. In November of 1888, Mary Baker Eddy adopted him as a son, perhaps with the hope of having a family member who could help her and carry on her work. He was one of the First Members of The Mother Church, later known as "Executive Members," who were the original members when the church was formed on September 23, 1892. There were twelve original First Members. He served as her publisher from 1893 to 1896. Ultimately, Foster Eddy proved to be disobedient, dishonest, and incompetent, despite Eddy's efforts to help him. He ultimately was expelled from the Church and later joined the “Next Friends” suit against Eddy.
