Why did Florence Nightingale become famous?

She became famous because, she saved thousands and thousands of lives during the crimean war! the hospitals back then were in a disgusting manner, blood, poo, rotting limbs were just lying on the bedsheets and the floor, florence helped all the hospitals by washing the floor and sheets, cleaning up wounds and showing the correct way, heal/help someone in need of assistance! During the war she was later known as the lady with the lamp, because as there was no electricity, and it was always dark in the hospitals so, she would carry around a candle, where ever she went! she was a real hero!
