This is a carte-de-visite image of Sarah (or Sally) Anderson Fremont. Her husband, Rear Admiral John C Fremont Jr., was the son of the famous ‘Pathfinder’ John C Fremont and his wife Jessie Benton. John Junior was born about 1851 and joined the U.S. Navy as a midshipman in June 1868 at the age of 17. He married Sally in 1877, and they had at least two daughters, and a son, the John C Fremont (III) born about 1880 who was listed as a cadet in the U.S. Naval Academy in Maryland in 1900. John C Fremont Junior died in 1911. In 1930 Sarah was still alive, residing in the Pemberton New Jersey home of her brother John Anderson.

The photographer for this public-domain image is ‘Otto’ of Paris. He was known for his photographs of celebrities and show-people, from the 1880s to the 1910s. This image is supposed to be about 1910, which is late for a CDV format image, but they did continue to publish them that late in France, especially for noted figures. Sally would have been about 50 in 1910, and was living in Boston at the time of the 1910 census, so perhaps this was taken a few years earlier on a trip to France.
