Florence Nightingale, (12 May 1820 – 13 August 1910) was a celebrated English nurse, writer and statistician. She came to prominence for her pioneering work in nursing during the Crimean War, where she tended to wounded soldiers. She was dubbed "The Lady with the Lamp" after her habit of making rounds at night. An Anglican, Nightingale believed that God had called her to be a nurse.
Nightingale laid the foundation of professional nursing with the establishment, in 1860, of her nursing school at St Thomas' Hospital in London, the first secular nursing school in the world, now part of King's College London. The Nightingale Pledge taken by new nurses was named in her honour, and the annual International Nurses Day is celebrated around the world on her birthday.
