Camilla A. Hanna (1847-1923) was born in Wisconsin and died in Pasadena, California. She lived in Fairview, Iowa, before moving to Council Bluffs, Iowa, around 1860. She earned a diploma in vocal music from Monticello Female Seminary in Godfrey, Illinois. She married Septimus J. Hanna, a county court judge in Council Bluffs, in 1869. They lived in Chicago from 1872 to 1879, where Septimus practiced law, and thereafter they moved to Leadville, Colorado, in hopes of improving his health. Camilla also struggled with poor health, and upon hearing that three friends in Council Bluffs had been healed through Christian Science treatment by Jennie B. Fenn, a student of Mary Baker Eddy's, she wrote to her family inquiring about it. Her father sent her a copy of Science and Health with Key to the Scriptures as a New Year's gift in 1886, and upon reading it, she was healed. Her healing inspired both her and her husband to begin the earnest study of Christian Science. They attended the National Christian Scientist Association in New York in 1890 and went directly from there to Scranton, Pennsylvania, where Septimus became the Pastor of the Christian Science Society and helped establish a church. The Hannas were listed in The Christian Science Journal as practitioners in Scranton in 1891 and 1892. In the fall of 1892, Mary Baker Eddy called them to Boston and gave them seven private lessons in Christian Science, as they had not studied with her previously, and they both went on to serve the cause of Christian Science in significant capacities in Boston over the following ten years. Camilla joined The First Church of Christ, Scientist, in Boston on October 5, 1892. She also became assistant editor of The Christian Science Journal in 1892, served on the Bible Lesson Committee in 1895, was instrumental in establishing the Christian Science Sentinel in September 1898, and was a member of Eddy's last Normal class in November 1898. When Septimus became a lecturer in 1902, the Hannas relocated to Colorado Springs, Colorado, and they finally settled in Pasadena, California, in 1911. Camilla was listed as a practitioner and teacher in The Christian Science Journal from 1904 until her passing.
