Florence Nightingale was born in 1820 and died in 1890. She trained as a nurse despite her parents' wishes and went to Crimea in 1853 to help wounded soldiers during the Crimean War. There, she found the hospital unsanitary and disorganized, but she and her nurses brought order and improved hygiene, saving many lives. After the war, Nightingale continued her nursing reforms and established the first nursing school in Britain.
