Florence Nightingale was born in Florence, Italy on May 12, 1820 and died in Mayfair, London, England on August 13, 1910. She died before the start of World War I, and being a British citizen was unlikely to have served in the U.S. Civil War. There were two Boer Wars, the first of which was from December 1880 - March 1881, when Nightingale was already in her sixties, and she did not serve there.

The Crimean War took place between October 1853 to March 1856 and Nightingale was charged with organizing the tending of wounded soldiers. Favorable coverage by the press gave her the name of "The Lady with the Lamp", and she became a heroine of the Victorian age.

In 1860, Nightingale laid the foundation of professional nursing with the establishment of her nursing school at St Thomas' Hospital in London.

She is also known for her many writings, and stands out as somebody who was acknowledged by Victorian England despite the fact that she really broke the mold for what a woman of her status was supposed to be. At that time, the daughters of wealthy Englishmen were not typically educated and were expected to quietly marry and have children.
