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 by many as the greatest novelist of the Victorian era. He worked as an attorney's clerk and newspaper reporter until his Sketches by Boz (1836) and The Pickwick Papers (1837) brought him the amazing and instant success that was to be his for the remainder of his life. In later years, the pressure of serial writing, editorial duties, lectures, and social commitments led to his separation from Catherine Hogarth after twenty-three years of marriage. It also hastened his death at the age of fifty-eight, when he was characteristically engaged in a multitude of work. His works enjoyed unprecedented popularity during his lifetime and, by the 20th century, critics and scholars had recognised him as a literary genius. His novels and short stories are widely read today.
