Ellen Newbold La Motte (1873–1961) was an American nurse, journalist and author. She began her nursing career as a tuberculosis nurse in Baltimore, Maryland, and in 1915 volunteered as one of the first American war nurses to go to Europe and treat soldiers in World War I. In Belgium she served in a French field hospital, keeping a bitter diary detailing the horrors that she witnessed daily. Back in America, she turned her diary into a book, The Backwash of War (1916), containing fourteen vignettes of typical scenes. The truth she told was unpalatable; the book was suppressed and not republished until 1934.
