No one knows if Florence Nightingale deliberately set out to become a nursing champion, but it is clear that the 1859 publication of her book Notes on Nursing: What It Is, And What It Is Not secured her place in nursing history. By the author's own admission, the work was not written as a training manual for nurses. Yet in many ways, this classic book, which was a best seller when issued and has been continuously in print since it was published 150 years ago, defines the precepts that became the prototype for contemporary nursing practice, provides a compelling historical perspective on the evolution of healthcare delivery, and provides an intimate glimpse into the Victorian Age. Although nurses no longer empty chamber pots, open chimney flues, or worry about their crinoline skirts catching fire, they may be interested to find among Nightingale's writings such modern-day concepts as the mind-body connection, plant therapy, and pet therapy.
