- Ellen Ternan is sometimes confused with her near contemporary, the Shakespearean actress Ellen Terry, whose career was more distinguished, but who did not have an affair with Dickens.
Ellen Lawless Ternan (3 March 1839 – 25 April 1914), also known as Nelly Ternan or Nelly Robinson, was an English actress who is mainly known as the mistress of Charles Dickens.
Ellen Lawless Ternan was born in Rochester, Kent. She was the third of four children, including a brother who died in infancy and a sister named Frances (later the second wife of Thomas Adolphus Trollope, the brother of Anthony Trollope). Her parents, Thomas Lawless Ternan and Frances Eleanor Ternan (née Jarman), were both actors of some distinction. Ternan made her stage debut in Sheffield at the age of three, and she and her two sisters were presented as "infant phenomena". Ellen was considered the least theatrically gifted of the three sisters, but she worked extensively in the provinces, particularly after her father died in October 1846, in the Bethnal Green Insane Asylum.
In 1857, she was spotted by Dickens performing at London's Haymarket Theatre. He cast her, on the recommendation of his friend the actor and playwright Alfred Wigan, along with her mother and sister Maria, in a performance of The Frozen Deep in Manchester in August 1857. It was not unusual for professional actresses to be invited to appear with amateur gentlemen; - Mrs Ternan played a Scottish nurse, Maria, the heroine Clara, and Nelly (Ellen) took over the girl's part from Katey Dickens- Dickens's seventeen-year-old daughter.  In mid-September 1857 he went with Wilkie Collins to Doncaster to see Ellen at the Theatre Royal in The Pet of the Petticoats, and wrote to John Forster that his relationship with his wife was disintegrating; 'Poor Catherine and I are not made for each other [-] What is now befalling I have seen steadily coming'. 
Dickens was forty-five when he met Ellen Ternan and she was eighteen, slightly older than his daughter Katey. Dickens began an affair with Ternan, but the relationship was kept secret from the general public. Ternan was clever and charming, forceful of character, and interested in literature and the theatre. Dickens referred to Ternan as his "magic circle of one". Matters came to a head in 1858 when Catherine Dickens opened a packet delivered by a London jeweller which contained a gold bracelet meant for Ternan with a note written by her husband. The Dickenses separated that May, after 22 years of marriage.
Ternan left the stage in 1860, and was supported by Dickens from then on. She sometimes travelled with him, and Dickens was travelling with Ternan and her mother back from a visit to France when they were both involved in the Staplehurst rail crash on 9 June 1865. He abandoned a plan to take her on his visit to America in 1867 for fear that their relationship would be publicised by the American press. She lived in houses he took under false names at Slough and later at Nunhead, and may have had a son by Dickens who died in infancy (neither Dickens, Ternan, nor Ternan's sisters left any account of the relationship, and most correspondence relevant to the relationship was destroyed). Dickens is thought by many scholars and commentators to have based several of his female characters on Ternan, including Estella in Great Expectations, Bella Wilfer in Our Mutual Friend and Helena Landless in The Mystery of Edwin Drood, and others may have been inspired by her, particularly Lucie Manette in A Tale of Two Cities. Dickens left a legacy of £1,000 to Ternan in his will on his death in 1870 and sufficient income from a trust fund to ensure that she would never have to work again.
In 1876, six years after Dickens' death, Ternan married George Wharton Robinson, an Oxford graduate, who was twelve years her junior. She presented herself as 14 years younger (23 years old rather than 37). The couple had a son, Geoffrey, and a daughter, Gladys, and ran a boys' school in Margate. Ternan's husband died in 1910, and she spent her last years in Southsea with her sister Frances. She died of cancer in Fulham, London.
The Dickens Fellowship and the surviving close family members of Charles Dickens maintained a facade of silence and denial about the affair from the time of Charles Dickens' death in 1870 until the death in December 1933 of his last surviving child, Sir Henry Fielding Dickens. Several Dickens researchers wrote about various aspects of the relationship between Ellen Ternan and Charles Dickens in the ensuing years, including Gladys Story in 1939, Ada Nisbet in 1952, Sir Felix Aylmer in 1959 and Katherine M Longley in 1985. Ellen Ternan was the subject of a bestselling biography by Claire Tomalin in 1990, which brought the relationship to a broader general audience. A summary of the story of the discovery of the relationship was published in 2012 by Professor Michael Slater.
In theatre and television
Simon Gray's play about her life, Little Nell had its world premiere in 2007 at the Theatre Royal, Bath. It was directed by Sir Peter Hall and starred Louise Brealey as Ternan. The affair was featured in the docudramas Dickens (BBC, 2002) and Dickens' Secret Lovers (2008, Channel 4 – it was the main subject of this programme, presented by Charles Dance and with Ternan played by Amy Shiels and Dickens by David Haig). Ternan is also featured in the novel Drood by Dan Simmons.
The Invisible Woman is a 2013 feature film about Ternan's relationship with Dickens. Ternan is played by Felicity Jones and Dickens by Ralph Fiennes, with the twenty-one-year age difference between them being similar to the real-life twenty-seven-year difference.
The subject of Nelly Ternan and her 13-year affair with Dickens is also the subject of "Dickens and Nelly", an original musical theater piece by librettist Barbara Zinn Krieger and composer Charlie Greenberg.
