Ellen B. Dietrick (1847-1895) was born in Morgantown, West Virginia, and died in Boston, Massachusetts. She was a suffragist, author, and social reformer, who was active in the women's suffrage movement in Kentucky and then Massachusetts. She founded the Kentucky Equal Rights Association (1888) and later served on the administration of the Massachusetts Woman Suffrage Association and the New England Woman Suffrage Association. Dietrick wrote and lectured on equal rights and authored two books, The Families of John and Jake (1889) and Women in the Early Christian Ministry (1897). In 1886 she wrote to Mary Baker Eddy to ask her to help heal a woman she knew in Covington. Eddy's response is not extant.
