William H. Bertram (1850-1911) was a lifelong resident of Boston, Massachusetts. He was a student of Mary Baker Eddy's, taking Primary class instruction twice (1884 and 1885). He was also an active member of the Christian Scientist Association and the Church of Christ (Scientist). In the spring of 1888, Bertram was part of a group of students that caused a split within the Association over its response to the Abby Corner court case. In April 1889, he was dismissed from the Church and, in May, withdrew from the Christian Scientist Association. After leaving the Christian Science movement, Bertram trained as a doctor. He graduated in 1891 from Boston's College of Physicians and Surgeons and afterwards maintained a practice in Boston. Though he had left the Christian Science movement, he maintained a cordial relationship with Eddy, corresponding occasionally with her.
