Elizabeth Cleghorn Gaskell (29 September 1810 - 12 November 1865), often referred to as Mrs Gaskell, was an English novelist, biographer, and short story writer. Her novels offer a detailed portrait of the lives of many strata of Victorian society, including the very poor, and are of interest to social historians as well as lovers of literature. Her first novel, Mary Barton, was published in 1848. Among Gaskell's best known novels are Cranford (1851-53), North and South (1854-55), and Wives and Daughters (1865), each having been adapted for television by the BBC. In early 1850 Gaskell wrote to Charles Dickens asking for advice about assisting a girl named Pasley whom she had visited in prison. Pasley provided her with a model for the title character of Ruth in 1853. Lizzie Leigh was published in March and April 1850, in the first numbers of Dickens's journal Household Words, in which many of her works were to be published. In June 1855 Patrick Brontë asked Gaskell to write a biography of his daughter Charlotte, and The Life of Charlotte Brontë was published in 1857. This played a significant role in developing Gaskell's own literary career.
