Hermanna R. Jantzen (1863-1954) was born in Lübeck, Schleswig-Holstein, Germany, and died in Colorado. Her family immigrated to the United States and settled in Mississippi in 1879. She moved to Longmont, Colorado, in 1881, and through the years she would move back and forth between Longmont, Boulder, and Denver, Colorado. For many years, Jantzen lived with the Hall family, who were instrumental in the early growth of Christian Science in Denver, and it is through them that she was introduced to Christian Science. She studied with Minnie B. Hall De Soto and Bradford Sherman, both students of Mary Baker Eddy, in 1886. Jantzen was on the Board of Directors of the Colorado Christian Science Institute in Denver during its establishment and was a member of the National Christian Scientist Association. She joined The First Church of Christ, Scientist, in Boston, Massachusetts, on June 11, 1901. Jantzen was listed in the directory of The Christian Science Journal as a Christian Science practitioner in Colorado from 1902 to 1951.
