John Keats was born in Moorgate, London, on 31 October 1795 to Thomas Keats and his wife, Frances Jennings. There is little evidence of his exact birthplace. Although Keats and his family seem to have marked his birthday on 29 October, baptism records give the date as the 31st. He was the eldest of four surviving children; his younger siblings were George (1797–1841), Thomas (1799–1818), and Frances Mary “Fanny” (1803–1889) who eventually married Spanish author Valentín Llanos Gutiérrez. Another son was lost in infancy. His father first worked as a hostler at the stables attached to the Swan and Hoop Inn, an establishment he later managed, and where the growing family lived for some years. Keats believed that he was born at the inn, a birthplace of humble origins, but there is no evidence to support his belief. The Globe pub now occupies the site (2012), a few yards from the modern-day Moorgate station. He was baptised at St Botolph-without-Bishopsgate, and sent to a local dame school as a child.

Letters and drafts of poems suggest that Keats first met Frances (Fanny) Brawne between September and November 1818. It is likely that the 18-year-old Brawne visited the Dilke family at Wentworth Place before she lived there. She was born in the hamlet of West End (now in the district of West Hampstead), on 9 August 1800. Like Keats’ grandfather, her grandfather kept a London inn, and both lost several family members to tuberculosis. She shared her first name with both Keats’ sister and mother, and had a talent for dress-making and languages as well as a natural theatrical bent. During November 1818 she developed an intimacy with Keats, but it was shadowed by the illness of Tom Keats, whom John was nursing through this period.

In April 1804, when Keats was eight, his father died from a skull fracture, suffered when he fell from his horse while returning from a visit to Keats and his brother George at school. Thomas Keats died intestate. Frances remarried two months later, but left her new husband soon afterwards, and the four children went to live with their grandmother, Alice Jennings, in the village of Edmonton.

His parents were unable to afford Eton or Harrow, so in the summer of 1803, he was sent to board at John Clarke’s school in Enfield, close to his grandparents’ house. The small school had a liberal outlook and a progressive curriculum more modern than the larger, more prestigious schools. In the family atmosphere at Clarke’s, Keats developed an interest in classics and history, which would stay with him throughout his short life. The headmaster’s son, Charles Cowden Clarke, also became an important mentor and friend, introducing Keats to Renaissance literature, including Tasso, Spenser, and Chapman’s translations. The young Keats was described by his friend Edward Holmes as a volatile character, “always in extremes”, given to indolence and fighting. However, at 13 he began focusing his energy on reading and study, winning his first academic prize in midsummer 1809.

In March 1810, when Keats was 14, his mother died of tuberculosis, leaving the children in the custody of their grandmother. She appointed two guardians, Richard Abbey and John Sandell, to take care of them. That autumn, Keats left Clarke’s school to apprentice with Thomas Hammond, a surgeon and apothecary who was a neighbour and the doctor of the Jennings family. Keats lodged in the attic above the surgery at 7 Church Street until 1813. Cowden Clarke, who remained a close friend of Keats, described this period as “the most placid time in Keats’ life.”

From 1814 Keats had two bequests, held in trust for him until his 21st birthday: £800, willed by his grandfather John Jennings (equivalent to about £56371 in 2019) and a quarter of his mother’s legacy of £8000 (equivalent to about £563705 in 2019), to be equally divided between her living children. It seems he was not told of the £800, and probably knew nothing of it, since he never applied for it. Historically, blame has often been laid on Abbey as legal guardian, but he may also have been unaware. William Walton, solicitor for Keats’ mother and grandmother, definitely did know and had a duty of care to relay the information to Keats. It seems he did not. The money would have made a critical difference to the poet’s expectations. Money was always a great concern and difficulty for him, as he struggled to stay out of debt and make his way in the world independently.

However, Keats’ training took up increasing amounts of his writing time, and he was increasingly ambivalent about his medical career. He felt that he faced a stark choice. He had written his first extant poem, “An Imitation of Spenser,” in 1814, when he was 19. Now, strongly drawn by ambition, inspired by fellow poets such as Leigh Hunt and Lord Byron, and beleaguered by family financial crises, he suffered periods of depression. His brother George wrote that John “feared that he should never be a poet, & if he was not he would destroy himself”. In 1816, Keats received his apothecary’s licence, which made him eligible to practise as an apothecary, physician, and surgeon, but before the end of the year he announced to his guardian that he was resolved to be a poet, not a surgeon.

Having finished his apprenticeship with Hammond, Keats registered as a medical student at Guy’s Hospital (now part of King’s College London) and began studying there in October 1815. Within a month of starting, he was accepted as a dresser at the hospital, assisting surgeons during operations, the equivalent of a junior house surgeon today. It was a significant promotion, that marked a distinct aptitude for medicine; it brought greater responsibility and a heavier workload. Keats’ long and expensive medical training with Hammond and at Guy’s Hospital led his family to assume he would pursue a lifelong career in medicine, assuring financial security, and it seems that at this point Keats had a genuine desire to become a doctor. He lodged near the hospital, at 28 St Thomas’s Street in Southwark, with other medical students, including Henry Stephens who became a famous inventor and ink magnate.

Although he continued his work and training at Guy’s, Keats devoted more and more time to the study of literature, experimenting with verse forms, particularly the sonnet. In May 1816, Leigh Hunt agreed to publish the sonnet “O Solitude” in his magazine, The Examiner, a leading liberal magazine of the day. It was the first appearance in print of Keats’ poetry, and Charles Cowden Clarke described it as his friend’s red letter day, the first proof that Keats’ ambitions were valid. Among his poems of 1816 was To My Brothers. In the summer of that year, Keats went with Clarke to the seaside town of Margate to write. There he began “Calidore” and initiated the era of his great letter writing. On his return to London, he took lodgings at 8 Dean Street, Southwark, and braced himself for further study in order to become a member of the Royal College of Surgeons.

In October 1816, Clarke introduced Keats to the influential Leigh Hunt, a close friend of Byron and Shelley. Five months later came the publication of Poems, the first volume of Keats’ verse, which included “I stood tiptoe” and “Sleep and Poetry,” both strongly influenced by Hunt. The book was a critical failure, arousing little interest, although Reynolds reviewed it favourably in The Champion. Clarke commented that the book “might have emerged in Timbuctoo.” Keats’ publishers, Charles and James Ollier, felt ashamed of the book. Keats immediately changed publishers to Taylor and Hessey on Fleet Street. Unlike the Olliers, Keats’ new publishers were enthusiastic about his work. Within a month of the publication of Poems they were planning a new Keats volume and had paid him an advance. Hessey became a steady friend to Keats and made the company’s rooms available for young writers to meet. Their publishing lists eventually included Coleridge, Hazlitt, Clare, Hogg, Carlyle and Lamb.

When Keats died at 25, he had been writing poetry seriously for only about six years, from 1814 until the summer of 1820; and publishing for only four. In his lifetime, sales of Keats’ three volumes of poetry probably amounted to only 200 copies. His first poem, the sonnet O Solitude, appeared in the Examiner in May 1816, while his collection Lamia, Isabella, The Eve of St. Agnes and other poems was published in July 1820 before his last visit to Rome. The compression of his poetic apprenticeship and maturity into so short a time is just one remarkable aspect of Keats’ work.

Having left his training at the hospital, suffering from a succession of colds, and unhappy with living in damp rooms in London, Keats moved with his brothers into rooms at 1 Well Walk in the village of Hampstead in April 1817. Both John and George nursed their brother Tom, who was suffering from tuberculosis. The house was close to Hunt and others from his circle in Hampstead, as well as to Coleridge, respected elder of the first wave of Romantic poets, at that time living in Highgate. On 11 April 1818, Keats reported that he and Coleridge had a long walk together on Hampstead Heath. In a letter to his brother George, Keats wrote that they talked about “a thousand things,… nightingales, poetry, poetical sensation, metaphysics.” Around this time he was introduced to Charles Wentworth Dilke and James Rice.

Keats befriended Isabella Jones in May 1817, while on holiday in the village of Bo Peep, near Hastings. She is described as beautiful, talented and widely read, not of the top flight of society yet financially secure, an enigmatic figure who would become a part of Keats’ circle. Throughout their friendship Keats never hesitates to own his sexual attraction to her, although they seem to enjoy circling each other rather than offering commitment. He writes that he “frequented her rooms” in the winter of 1818–19, and in his letters to George says that he “warmed with her” and “kissed her”. The trysts may have been a sexual initiation for Keats according to Bate and Gittings. Jones inspired and was a steward of Keats’ writing. The themes of “The Eve of St. Agnes” and “The Eve of St Mark” may well have been suggested by her, the lyric Hush, Hush! [“o sweet Isabel”] was about her, and that the first version of “Bright Star” may have originally been for her. In 1821, Jones was one of the first in England to be notified of Keats’ death.

In June 1818, Keats began a walking tour of Scotland, Ireland, and the Lake District with his friend Charles Armitage Brown. Keats’ brother George and his wife Georgina accompanied them as far as Lancaster and then continued to Liverpool, from where the couple emigrated to America. They lived in Ohio and Louisville, Kentucky, until 1841, when George’s investments failed. Like Keats’ other brother, they both died penniless and racked by tuberculosis, for which there was no effective treatment until the next century. In July, while on the Isle of Mull, Keats caught a bad cold and “was too thin and fevered to proceed on the journey.” After his return south in August, Keats continued to nurse Tom, exposing himself to infection. Some biographers suggest that this is when tuberculosis, his “family disease,” first took hold. “Consumption” was not identified as a disease with a single infectious origin until 1820, and there was considerable stigma attached to the condition, as it was often associated with weakness, repressed sexual passion, or masturbation. Keats “refuses to give it a name” in his letters. Tom Keats died on 1 December 1818.

In 1819, Keats wrote “The Eve of St. Agnes”, “La Belle Dame sans Merci”, “Hyperion”, “Lamia” and a play, Otho the Great (critically damned and not performed until 1950). The poems “Fancy” and “Bards of passion and of mirth” were inspired by the garden of Wentworth Place. In September, very short of money and in despair considering taking up journalism or a post as a ship’s surgeon, he approached his publishers with a new book of poems. They were unimpressed with the collection, finding the presented versions of “Lamia” confusing, and describing “St Agnes” as having a “sense of pettish disgust” and “a ‘Don Juan’ style of mingling up sentiment and sneering” concluding it was “a poem unfit for ladies”. The final volume Keats lived to see, Lamia, Isabella, The Eve of St. Agnes, and Other Poems, was eventually published in July 1820. It received greater acclaim than had Endymion or Poems, finding favourable notices in both The Examiner and Edinburgh Review. It would come to be recognised as one of the most important poetic works ever published.

On 3 April 1819, Brawne and her widowed mother moved into the other half of Dilke’s Wentworth Place, and Keats and Brawne were able to see each other every day. Keats began to lend Brawne books, such as Dante’s Inferno, and they would read together. He gave her the love sonnet “Bright Star” (perhaps revised for her) as a declaration. It was a work in progress which he continued at until the last months of his life, and the poem came to be associated with their relationship. “All his desires were concentrated on Fanny”. From this point there is no further documented mention of Isabella Jones. Sometime before the end of June, he arrived at some sort of understanding with Brawne, far from a formal engagement as he still had too little to offer, with no prospects and financial stricture. Keats endured great conflict knowing his expectations as a struggling poet in increasingly hard straits would preclude marriage to Brawne. Their love remained unconsummated; jealousy for his ‘star’ began to gnaw at him. Darkness, disease and depression surrounded him, reflected in poems such as “The Eve of St. Agnes” and “La Belle Dame sans Merci” where love and death both stalk. “I have two luxuries to brood over in my walks;” he wrote to her, “…your loveliness, and the hour of my death”.

He used the term negative capability to discuss the state in which we are “capable of being in uncertainties, Mysteries, doubts without any irritable reaching after fact & reason …[Being] content with half knowledge” where one trusts in the heart’s perceptions. He wrote later: “I am certain of nothing but the holiness of the Heart’s affections and the truth of Imagination – What the imagination seizes as Beauty must be truth – whether it existed before or not – for I have the same Idea of all our Passions as of Love they are all in their sublime, creative of essential Beauty” again and again turning to the question of what it means to be a poet. “My Imagination is a Monastery and I am its Monk”, Keats notes to Shelley. In September 1819, Keats wrote to Reynolds “How beautiful the season is now – How fine the air. A temperate sharpness about it … I never lik’d the stubbled fields as much as now – Aye, better than the chilly green of spring. Somehow the stubble plain looks warm – in the same way as some pictures look warm – this struck me so much in my Sunday’s walk that I composed upon it”. The final stanza of his last great ode, “To Autumn”, runs:

Tuberculosis took hold and he was advised by his doctors to move to a warmer climate. In September 1820 Keats left for Rome knowing he would probably never see Brawne again. After leaving he felt unable to write to her or read her letters, although he did correspond with her mother. He died there five months later. None of Brawne’s letters to Keats survive.

During 1820 Keats displayed increasingly serious symptoms of tuberculosis, suffering two lung haemorrhages in the first few days of February. On first coughing up blood, on 3 February 1820, he said to Charles Armitage Brown, “I know the colour of that blood! It is arterial blood. I cannot be deceived in that colour. That drop of blood is my death warrant. I must die.”

Keats wrote his last letter on 30 November 1820 to Charles Armitage Brown; “Tis the most difficult thing in the world to me to write a letter. My stomach continues so bad, that I feel it worse on opening any book – yet I am much better than I was in Quarantine. Then I am afraid to encounter the proing and conning of any thing interesting to me in England. I have an habitual feeling of my real life having past, and that I am leading a posthumous existence”.

On arrival in Italy, he moved into a villa on the Spanish Steps in Rome, today the Keats–Shelley Memorial House museum. Despite care from Severn and Dr. James Clark, his health rapidly deteriorated. The medical attention Keats received may have hastened his death. In November 1820, Clark declared that the source of his illness was “mental exertion” and that the source was largely situated in his stomach. Clark eventually diagnosed consumption (tuberculosis) and placed Keats on a starvation diet of an anchovy and a piece of bread a day intended to reduce the blood flow to his stomach. He also bled the poet: a standard treatment of the day, but also likely a significant contributor to Keats’ weakness. Severn’s biographer Sue Brown writes: “They could have used opium in small doses, and Keats had asked Severn to buy a bottle of opium when they were setting off on their voyage. What Severn didn’t realise was that Keats saw it as a possible resource if he wanted to commit suicide. He tried to get the bottle from Severn on the voyage but Severn wouldn’t let him have it. Then in Rome he tried again… Severn was in such a quandary he didn’t know what to do, so in the end he went to the doctor who took it away. As a result Keats went through dreadful agonies with nothing to ease the pain at all.” Keats was angry with both Severn and Clark when they would not give him laudanum (opium). He repeatedly demanded “how long is this posthumous existence of mine to go on?”

Although prolific during his short career, and now one of the most studied and admired British poets, his reputation rests on a small body of work, centred on the Odes, and only in the creative outpouring of the last years of his short life was he able to express the inner intensity for which he has been lauded since his death. Keats was convinced that he had made no mark in his lifetime. Aware that he was dying, he wrote to Fanny Brawne in February 1820, “I have left no immortal work behind me – nothing to make my friends proud of my memory – but I have lov’d the principle of beauty in all things, and if I had had time I would have made myself remember’d.”

John Keats died in Rome on 23 February 1821. His body was buried in the city’s Protestant Cemetery. His last request was to be placed under a tombstone bearing no name or date, only the words, “Here lies One whose Name was writ in Water.” Severn and Brown erected the stone, which under a relief of a lyre with broken strings, includes the epitaph:

It took a month for the news of his death to reach London, after which Brawne stayed in mourning for six years. In 1833, more than 12 years after his death, she married and went on to have three children; she outlived Keats by more than 40 years.

The Victorian sense of poetry as the work of indulgence and luxuriant fancy offered a schema into which Keats was posthumously fitted. Marked as the standard-bearer of sensory writing, his reputation grew steadily and remarkably. His work had the full support of the influential Cambridge Apostles, whose members included the young Tennyson, later a popular Poet Laureate who came to regard Keats as the greatest poet of the 19th century. Constance Naden was a great admirer of his poems, arguing that his genius lay in his ‘exquisite sensitiveness to all the elements of beauty’. In 1848, twenty-seven years after Keats’ death, Richard Monckton Milnes published the first full biography, which helped place Keats within the canon of English literature. The Pre-Raphaelite Brotherhood, including Millais and Rossetti, were inspired by Keats and painted scenes from his poems including “The Eve of St. Agnes”, “Isabella” and “La Belle Dame sans Merci”, lush, arresting and popular images which remain closely associated with Keats’ work.

Shelley promoted Keats as someone whose achievement could not be separated from agony, who was ‘spiritualised’ by his decline and too fine-tuned to endure the harshness of life; the consumptive, suffering image popularly held today. The first full biography was published in 1848 by Richard Monckton Milnes. Landmark Keats biographers since include Sidney Colvin, Robert Gittings, Walter Jackson Bate, Aileen Ward, and Andrew Motion. The idealised image of the heroic romantic poet who battled poverty and died young was inflated by the late arrival of an authoritative biography and the lack of an accurate likeness. Most of the surviving portraits of Keats were painted after his death, and those who knew him held that they did not succeed in capturing his unique quality and intensity.

Keats’ letters were first published in 1848 and 1878. During the 19th century, critics deemed them unworthy of attention, distractions from his poetic works. During the 20th century they became almost as admired and studied as his poetry, and are highly regarded within the canon of English literary correspondence. T. S. Eliot described them as “certainly the most notable and most important ever written by any English poet.” Keats spent a great deal of time considering poetry itself, its constructs and impacts, displaying a deep interest unusual amongst his milieu who were more easily distracted by metaphysics or politics, fashions or science. Eliot wrote of Keats’ conclusions; “There is hardly one statement of Keats’ about poetry which … will not be found to be true, and what is more, true for greater and more mature poetry than anything Keats ever wrote.”

There are areas of his life and daily routine that Keats does not describe. He mentions little about his childhood or his financial straits and is seemingly embarrassed to discuss them. There is a total absence of any reference to his parents. In his last year, as his health deteriorated, his concerns often give way to despair and morbid obsessions. The publications of letters to Fanny Brawne in 1870 focus on this period and emphasise this tragic aspect, giving rise to widespread criticism at the time.

In 1882, Swinburne wrote in the Encyclopædia Britannica that “the Ode to a Nightingale, [is] one of the final masterpieces of human work in all time and for all ages”. In the twentieth century, Keats remained the muse of poets such as Wilfred Owen, who kept his death date as a day of mourning, Yeats and T. S. Eliot. Critic Helen Vendler stated the odes “are a group of works in which the English language find ultimate embodiment”. Bate declared of To Autumn: “Each generation has found it one of the most nearly perfect poems in English” and M. R. Ridley claimed the ode “is the most serenely flawless poem in our language.”

The largest collection of the letters, manuscripts, and other papers of Keats is in the Houghton Library at Harvard University. Other collections of material are archived at the British Library, Keats House, Hampstead, the Keats-Shelley Memorial House in Rome and the Pierpont Morgan Library in New York. Since 1998 the British Keats-Shelley Memorial Association have annually awarded a prize for romantic poetry. A Royal Society of Arts blue plaque was unveiled in 1896 to commemorate Keats at Keats House.

John Keats: His Life and Death, the first major motion picture about the life of Keats, was produced in 1973 by Encyclopædia Britannica, Inc.. It was directed by John Barnes. John Stride played John Keats and Janina Faye played Fanny Brawne.

The 2009 film Bright Star, written and directed by Jane Campion, focuses on Keats’ relationship with Fanny Brawne. Inspired by the 1997 Keats biography penned by Andrew Motion, it stars Ben Whishaw as Keats and Abbie Cornish as Fanny.
