Charles John Huffam Dickens (7 February 1812 - 9 June 1870) was an English writer and social critic. He created some of the world's best-known fictional characters and is regarded as the greatest novelist of the Victorian era. His works enjoyed unprecedented popularity during his lifetime, and by the twentieth century critics and scholars had recognised him as a literary genius. His novels and short stories enjoy lasting popularity.

Born in Portsmouth, Dickens left school to work in a factory when his father was incarcerated in a debtors' prison. Despite his lack of formal education, he edited a weekly journal for 20 years, wrote 15 novels, five novellas, hundreds of short stories and non-fiction articles, lectured and performed extensively, was an indefatigable letter writer, and campaigned vigorously for children's rights, education, and other social reforms.

Dickens was regarded as the literary colossus of his age. His 1843 novella, A Christmas Carol, remains popular and continues to inspire adaptations in every artistic genre. Oliver Twist and Great Expectations are also frequently adapted, and, like many of his novels, evoke images of early Victorian London. His 1859 novel, A Tale of Two Cities, set in London and Paris, is his best-known work of historical fiction.
