Sarah I. Bertram (1852-1927) was born in Hamilton, Ontario, and died in St. Petersburg, Florida. She was a student of Mary Baker Eddy's, completing the Primary class in 1884 and joining the Christian Scientist Association and Church of Christ (Scientist) shortly afterwards. In the spring of 1888, Bertram's husband, William H. Bertram, and a group of students caused a split within the Association over its response to the Abby Corner court case. In April 1889, she was dismissed from the Church and, in May, withdrew from the Christian Scientist Association.
