Mary Wollstonecraft Shelley (; 30 August 1797 – 1 February 1851) was an English novelist who wrote the Gothic novel Frankenstein; or, The Modern Prometheus (1818), which is considered an early example of science fiction. She also edited and promoted the works of her husband, the Romantic poet and philosopher Percy Bysshe Shelley. Her father was the political philosopher William Godwin and her mother was the philosopher and women's rights advocate Mary Wollstonecraft.

Mary's mother died 11 days after giving birth to her. She was raised by her father, who provided her with a rich informal education, encouraging her to adhere to his own anarchist political theories. When she was four, her father married a neighbour, Mary Jane Clairmont, with whom Mary had a troubled relationship.

In 1814, Mary began a romance with one of her father's political followers, Percy Bysshe Shelley, who was already married. Together with her stepsister, Claire Clairmont, she and Percy left for France and travelled through Europe. Upon their return to England, Mary was pregnant with Percy's child. Over the next two years, she and Percy faced ostracism, constant debt and the death of their prematurely born daughter. They married in late 1816, after the suicide of Percy Shelley's wife, Harriet.

In 1816, the couple and Mary's stepsister famously spent a summer with Lord Byron and John William Polidori near Geneva, Switzerland, where Shelley conceived the idea for her novel Frankenstein. The Shelleys left Britain in 1818 for Italy, where their second and third children died before Shelley gave birth to her last and only surviving child, Percy Florence Shelley. In 1822, her husband drowned when his sailing boat sank during a storm near Viareggio. A year later, Shelley returned to England and from then on devoted herself to raising her son and to her career as a professional author. The last decade of her life was dogged by illness, most likely caused by the brain tumour which killed her at the age of 53.

Until the 1970s, Shelley was known mainly for her efforts to publish her husband's works and for her novel Frankenstein, which remains widely read and has inspired many theatrical and film adaptations. Recent scholarship has yielded a more comprehensive view of Shelley's achievements. Scholars have shown increasing interest in her literary output, particularly in her novels, which include the historical novels Valperga (1823) and Perkin Warbeck (1830), the apocalyptic novel The Last Man (1826) and her final two novels, Lodore (1835) and Falkner (1837). Studies of her lesser-known works, such as the travel book Rambles in Germany and Italy (1844) and the biographical articles for Dionysius Lardner's Cabinet Cyclopaedia (1829–1846), support the growing view that Shelley remained a political radical throughout her life. Shelley's works often argue that cooperation and sympathy, particularly as practised by women in the family, were the ways to reform civil society. This view was a direct challenge to the individualistic Romantic ethos promoted by Percy Shelley and the Enlightenment political theories articulated by her father, William Godwin.

Life and career

Early life

Mary Shelley was born Mary Wollstonecraft Godwin in Somers Town, London, in 1797. She was the second child of the feminist philosopher, educator, and writer Mary Wollstonecraft and the first child of the philosopher, novelist, and journalist William Godwin. Wollstonecraft died of puerperal fever shortly after Mary was born. Godwin was left to bring up Mary, along with her older half-sister, Fanny Imlay, Wollstonecraft's child by the American speculator Gilbert Imlay.Seymour, 28–29; St Clair, 176–178. A year after Wollstonecraft's death, Godwin published his Memoirs of the Author of A Vindication of the Rights of Woman (1798), which he intended as a sincere and compassionate tribute. However, because the Memoirs revealed Wollstonecraft's affairs and her illegitimate child, they were seen as shocking. Mary Godwin read these memoirs and her mother's books, and was brought up to cherish her mother's memory.St Clair, 179–188; Seymour, 31–34; Clemit, Legacies of Godwin and Wollstonecraft (CC), 27–28.

Mary's earliest years were happy, judging from the letters of William Godwin's housekeeper and nurse, Louisa Jones.Seymour, 38, 49; St. Clair, 255–300. But Godwin was often deeply in debt; feeling that he could not raise the children by himself, he cast about for a second wife.St Clair, 199–207. In December 1801, he married Mary Jane Clairmont, a well-educated woman with two young children of her own – Charles and Claire.Claire's first name was "Jane", but from 1814 (see Gittings and Manton, 22) she preferred to be called "Claire" (her second name was "Clara"), which is how she is known to history. To avoid confusion, this article calls her "Claire" throughout. Most of Godwin's friends disliked his new wife, describing her as quick-tempered and quarrelsome;Seymour, 47–49; St Clair, 238–254.William St Clair, in his biography of the Godwins and the Shelleys, notes that "it is easy to forget in reading of these crises [in the lives of the Godwins and the Shelleys] how unrepresentative the references in surviving documents may be. It is easy for the biographer to give undue weight to the opinions of the people who happen to have written things down." (246) but Godwin was devoted to her, and the marriage was a success.St Clair, 243–244, 334; Seymour, 48. Mary Godwin, in contrast, came to detest her stepmother.Letter to Percy Shelley, 28 October 1814. Selected Letters, 3; St Clair, 295; Seymour 61. William Godwin's 19th-century biographer Charles Kegan Paul later suggested that Mrs Godwin had favoured her own children over those of Mary Wollstonecraft.St Clair, 295.

Together, the Godwins started a publishing firm called M. J. Godwin, which sold children's books as well as stationery, maps, and games. However, the business did not turn a profit, and Godwin was forced to borrow substantial sums to keep it going.St. Clair, 283–287. He continued to borrow to pay off earlier loans, compounding his difficulties. By 1809, Godwin's business was close to failure, and he was "near to despair".St. Clair, 306. Godwin was saved from debtor's prison by philosophical devotees such as Francis Place, who lent him further money.St. Clair, 308–309.

Though Mary Godwin received little formal education, her father tutored her in a broad range of subjects. He often took the children on educational outings, and they had access to his library and to the many intellectuals who visited him, including the Romantic poet Samuel Taylor Coleridge and the former vice-president of the United States Aaron Burr.Bennett, An Introduction, 16–17. Godwin admitted he was not educating the children according to Mary Wollstonecraft's philosophy as outlined in works such as A Vindication of the Rights of Woman (1792), but Mary Godwin nonetheless received an unusual and advanced education for a girl of the time. She had a governess and a daily tutor and read many of her father's children's books on Roman and Greek history in manuscript.Sunstein, 38–40; Seymour, 53; see also Clemit, "Legacies of Godwin and Wollstonecraft" (CC), 29. For six months in 1811, she also attended a boarding school in Ramsgate.Seymour, 61. Her father described her at age 15 as "singularly bold, somewhat imperious, and active of mind. Her desire of knowledge is great, and her perseverance in everything she undertakes almost invincible."Sunstein, 58; Spark, 15.

In June 1812, Mary's father sent her to stay with the dissenting family of the radical William Baxter, near Dundee, Scotland.Seymour, 74–75. To Baxter, he wrote, "I am anxious that she should be brought up ... like a philosopher, even like a cynic."Quoted in Seymour, 72. Scholars have speculated that she was sent away for her health, to remove her from the seamy side of the business, or to introduce her to radical politics.Seymour, 71–74. Mary Godwin revelled in the spacious surroundings of Baxter's house and in the companionship of his four daughters, and she returned north in the summer of 1813 for a further stay of 10 months.Spark, 17–18; Seymour, 73–86. In the 1831 introduction to Frankenstein, she recalled: "I wrote then—but in a most common-place style. It was beneath the trees of the grounds belonging to our house, or on the bleak sides of the woodless mountains near, that my true compositions, the airy flights of my imagination, were born and fostered."Qtd. in Spark, 17.

Percy Bysshe Shelley

Mary Godwin may have first met the radical poet-philosopher Percy Bysshe Shelley in the interval between her two stays in Scotland.Bennett, An Introduction, 17; St Clair, 357; Seymour, 89. By the time she returned home for a second time on 30 March 1814, Percy Shelley had become estranged from his wife and was regularly visiting William Godwin, whom he had agreed to bail out of debt.Sunstein, 70–75; Seymour, 88; St. Clair, 329–335. Percy Shelley's radicalism, particularly his economic views, which he had imbibed from William Godwin's Political Justice (1793), had alienated him from his wealthy aristocratic family: they wanted him to follow traditional models of the landed aristocracy, and he wanted to donate large amounts of the family's money to schemes intended to help the disadvantaged. Percy Shelley, therefore, had difficulty gaining access to money until he inherited his estate because his family did not want him wasting it on projects of "political justice". After several months of promises, Shelley announced that he either could not or would not pay off all of Godwin's debts. Godwin was angry and felt betrayed.St. Clair, 355.

Mary and Percy began meeting each other secretly at her mother Mary Wollstonecraft's grave in the churchyard of St Pancras Old Church, and they fell in love—she was 16, and he was 21.Spark, 19–22; St Clair, 358. On 26 June 1814, Shelley and Godwin declared their love for each other as Shelley announced he could not hide his "ardent passion", leading her in a "sublime and rapturous moment" to say she felt the same way; on either that day or the next, Godwin lost her virginity to Shelley, which tradition claims happened in the churchyard.Garrett, 19. Godwin described herself as attracted to Shelley's "wild, intellectual, unearthly looks".Garrett, 20. To Mary's dismay, her father disapproved, and tried to thwart the relationship and salvage the "spotless fame" of his daughter. At about the same time, Mary's father learned of Shelley's inability to pay off the father's debts.Seymour, 94, 100; Spark, 22–23; St. Clair, 355. Mary, who later wrote of "my excessive and romantic attachment to my father",Letter to Maria Gisborne, 30 October – 17 November 1834. Seymour, 49. was confused. She saw Percy Shelley as an embodiment of her parents' liberal and reformist ideas of the 1790s, particularly Godwin's view that marriage was a repressive monopoly, which he had argued in his 1793 edition of Political Justice but later retracted.St Clair, 373; Seymour, 89 n, 94–96; Spark, 23 n2. On 28 July 1814, the couple eloped and secretly left for France, taking Mary's stepsister, Claire Clairmont, with them.Spark, 24; Seymour, 98–99.
