Florence Nightingale is famous for changing the way nurses were perceived during her time, raising the standards for nursing, and educating nurses.
First of all, when she arrived in Turkey in 1854 during the Crimean War, she found the conditions in the hospital to be horrid. Wounded soldiers were lying in filth which included dirty clothes and bloodied bandages. Most were dying from the spread of disease rather than their wounds. The first thing she did with her team of nurses was scrub the hospital from top to bottom, provide clean clothing, and make conditions, overall, sanitary.
Secondly, prior to Nightingale, nursing was thought of as a lowly profession, much like that of a servant. She fought to raise the standards of nursing, highlighting sanitary conditions, educating patients so they could care for themselves, and assessing patients' conditions around the clock. When she made her way to check on the patients during the night, she carried a lamp with her. For this she was named "The Lady with the Lamp." Her patient assessment is now known as "making the rounds" in today's modern hospitals. Because of her dedication, nursing became an honored profession.
Lastly, she was recognized by Queen Victoria, who gave her a jeweled brooch. Also, she was the first woman to be given honorary membership in the Royal Statistical Society. Nightingale also published a book on nursing. She is famous for these remarkable feats.
