Her birthday is International Nurse's Day (May 12)

from Writer's Almanac (American Public Media - Garrison Keillor):
May 12 is the birthday of Florence Nightingale (1820), the founder of modern nursing. Nightingale was born to a wealthy English family in Florence, Italy, and raised in London. Her father believed girls should be educated, which was unusual for the time, and tutored Nightingale in Latin, Greek, philosophy, and mathematics. Later in life, she became an excellent statistician, inventing the pie chart as a way to explain the spread of contagious disease.
Her parents forbade her to enter nursing, which was considered a working-class occupation. Her mother wanted her to marry, but Nightingale refused. She wrote to a friend, “God called me in the morning and asked me would I do good for him alone without reputation.” In 1850, she visited the Lutheran religious community at Kaiserswerth-am-Rhein in Germany, where she observed the deaconesses caring for the deprived and ill. She took four months of medical training there, the foundation for her future as a nurse.
Returning to London, she took a position at the Institute for the Care of Sick Gentlewomen. Her father, resigned, supported her financially. Her mother wrote to a friend, “I do not expect that love passages will be frequent in her life.” Indeed, Nightingale did have suitors, and one in particular for nine years, but she broke it off, thinking it would interfere with her vocation.
During the Crimean War, British citizens were outraged to learn their wounded soldiers were being treated poorly. In October of 1854, Nightingale gathered 38 volunteer nurses and 15 Catholic nuns and traveled to the Ottoman Empire. They were horrified to find that the British hospital sat over a large cesspool, which had contaminated the water. Water was being rationed, rodents roamed in large numbers, medicine was scarce, and hygienic practices were nil. Nightingale established a laundry, kitchen, classroom, even a library, and instituted hand-washing procedures for everyone. During her war service, she reduced the death rate from 42 percent to 2 percent, mostly by introducing sanitary reforms, which helped control the spread of infection. She advocated for personal care for patients, roaming the hallways at night with a lantern, chatting with the wounded. She became known as the “Lady with the Lamp,” and the Times of London said of her, “She is a ‘ministering angel,’ without any exaggeration in these hospitals, and as her slender form glides quietly along each corridor, every poor fellow’s face softens with gratitude at the sight of her.”
After the war, Nightingale was treated like a hero for her efforts, though she generally spurned the attention, saying: “They (patients) don’t want you to be lachrymose and whining with them, they like you to be fresh and active and interested. [...] A sick person does so enjoy hearing good news.”
When she returned to London, she established the Nightingale Training School to train nurses. It is now called the Florence Nightingale School of Nursing and Midwifery and is part of King’s College, London.
Her book Notes on Nursing: What it is and What it is not (1859) was one of the first texts on the nursing practice and even sold well to the public. It’s still considered a cornerstone of the nursing curriculum and includes advice and practice on procedures such as the cleanliness of rooms, observation of the sick, and ventilation and warming. Her ideas on patient room design have influenced hospital architecture this day. She said, “I have seen [...] the most acute suffering produced from the patient not being able to see out of the window and the knots of the wood being the only view.”
Nightingale’s birthday is International Nurses Day, a celebration that marks the contributions of nurses to society. It’s been celebrated by the International Council of Nurses since 1965. Australia chooses a Nurse of the Year. In China, nurses recite the Florence Nightingale Pledge, a modified version of the Hippocratic oath, created in 1893. It reads, in part: “May my life be devoted to service and to the high ideals of the nursing profession.” In the U.K., during a service at Westminster Abbey, a symbolic lamp is taken from the Nurses’ Chapel in the Abbey and handed from one nurse to another, then to the Dean, who places it on the High Altar. The lamp symbolizes Nightingale’s lantern, which is now on display in the Florence Nightingale Museum in London, along her with stuffed pet owl, her letters, and her nursing uniform.
Florence Nightingale said, “Women should have the true nurse calling, the good of the sick first, the second only the consideration of what is their ‘place’ to do — and that women who want for a housemaid to do this or the charwomen to do that, when the patient is suffering, have not the making of a nurse in them.”
