Mary Phinney von Olnhausen

Mary Phinney von Olnhausen (1818–1902) was an American nurse, abolitionist, and diarist. Historians look to the book extracted from her diaries -- "Adventures of an Army Nurse in Two Wars" to understand the medical techniques of the Civil War.
Born in Massachusetts to Elias and Catherine Bartlett Phinney, a lawyer and her mother the daughter of a doctor, Phinney was well educated at several academies. When her father died in 1849 at age 69, the farm was sold and she "sought employment as a designer of print goods" at the mills. There she met Gustav, Baron von Olnhausen (1809–1860) who left Saxony after the 1848 unrest and financial troubles, which led to selling of his property. He was making a meager living as a chemist in a dye-house of the Manchester Mills. They married when she was 40 years old on May 1, 1858 and he died two years later in 1860.
During the US Civil War, von Olnhausen served as a nurse at the Mansion House Hospital in Alexandria, Virginia and Mansfield General Hospital at Morehead, North Carolina. After the war, she was discharged in August 1865, returning home to help raise her brother's children in Illinois. With the outbreak of the Franco-Prussian War in 1870, she volunteered to serve as a nurse with the Prussian Army and was accepted on the basis of being the Baroness von Olnhausen. She served in field hospitals in Meung and Vendome, work for which she was awarded a Cross of Merit for Women and Girls in 1873 by Kaiser Wilhelm I, which is similar to an Iron Cross. She died in Boston in April, 1902.
Fictional portrayal.
In 2015, the "PBS Masterpiece Theatre" series-produced the twelve-episode cancelled miniseries, "Mercy Street", about the Mansion House Hospital, where Phinney was stationed, that relied heavily on her diaries. A character based on Phinney, and named after Phinney, is played by Mary Elizabeth Winstead and is the series' lead character.
