Florence Nightingale was born in 1820 in Italy to wealthy parents and received an advanced education despite norms of the time favoring men's education. She felt called to nursing at age 17 despite her family's objections. After training, she volunteered in the Crimean War, finding barrack hospitals unsanitary. Through organizing nurses and employing sanitation practices, she reduced death rates dramatically, becoming known as the "Lady with the Lamp." After the war, she advanced nursing standards through the first nursing textbook and curriculum, establishing it as a respected profession.
