I found this article today which includes a picture of the hospital where Louisa served during the Civil War, plus a photo of the first edition of Hospital Sketches. The diary which the author refers to can be downloaded for free on Google Books.
The author is Kevin Konrad, a graduate from the Richard Stockton College of New Jersey and an exhibition researcher.
Scenes from the Hurly Burly Hotel: Louisa May Alcott’s Civil War
“As no two persons see the same thing with the same eyes, my view of hospital life must be taken through my glass, and held for what it is worth.” – Louisa May Alcott, Hospital Sketches
Before performing preliminary research on Civil War-era nursing for the National Library of Medicine’s joint exhibition with the National Museum of American History, I knew little about the hard-working and dedicated women who served in overcrowded hospitals and on war-torn battlefields. Of all the women I read about, the only name that seemed familiar to me was Clara Barton, founder of the American Red Cross. It was not until I read the diary of Amanda Akin, the subject of the aforementioned exhibit, that another name caught my attention: Louisa May Alcott.
