What were two key people in the mid 1800s?

Charles Dickens (1812–1870) was an English writer and social critic. He created some of the world's most well-known fictional characters, including Oliver Twist, David Copperfield, and Ebenezer Scrooge. Dickens's novels often explored themes of poverty, social injustice, and the human condition. He was also a fierce critic of the Victorian class system.

Florence Nightingale (1820–1910) was an English nurse, social reformer, and statistician. She is considered the founder of modern nursing. Nightingale played a key role in reforming the nursing profession and improving hospital conditions. She also established the first nursing school in the world, the Nightingale Training School for Nurses, in 1860. Nightingale's work had a profound impact on the field of nursing and on the lives of women around the world.
