I like your article, but I think Mary Seacole was perhaps a better role model, she went to the front line with the soldiers.
"Historians are now waking up to the shocking truth that the death toll at Nightingale's hospital was higher than at any other hospital in the East, and that her lack of knowledge of the disastrous sanitary conditions at Scutari was responsible. During her first winter at Scutari, 4,077 soldiers died there, ten times more from illnesses such as typhus, typhoid, cholera and dysentery, than from battle wounds. Conditions at the hospital were fatal to the men that Nightingale was trying to nurse: they were packed like sardines into an unventilated building on top of defective sewers." and "...when examined closely, the accepted doctrine that she saved soldiers' lives in her hospital suddenly dissolves before our eyes. And it has also allowed us to forget that Nightingale's priority on returning from the Crimea was not the reform of civilian nursing in Britain, but rather a thorough overhaul of the health of the army in peacetime."
