In July 1860, the world’s first nursing school opened at St. Thomas Hospital in London. Today that school is part of the King’s College, where nursing students are called Nightingales. The school—like modern nursing itself—was established by Florence Nightingale, who revolutionized nursing during the Crimean War. When prospective nurses complete their training, they take the “Nightingale Pledge,” a reflection of her ongoing impact on nursing.
