Mary Shelley died on 1st February 1851 at Chester Square in London, England of brain cancer. After her death Percy arranged for the bodies of her father Godwin and her mother Mary Wollstonecraft to be exhumed and reburied alongside Mary at St. Peter’s Church in Bournemouth.


Mary Shelley’s mother Mary Wollstonecraft died when she was only a few days old and she was looked after by her father the philosopher William Godwin and her stepmother whom she disliked. She never went to school but her father encouraged her to read widely. Particular favourites were the poetry of John Milton and the plays of William Shakespeare. Her parents were influenced by Enlightenment ideals expressed in the works of John Locke and Jean-Jacques Rousseau and this permeated through to Mary who was allowed to use her father’s extensive library. She read and reread her mother’s books all her life committing many to heart. Her father encouraged her to write letters to people and she enjoyed making up stories.

Other more recent writers who influenced her were Johann Wolfgang von Goethe whose, famous novel of tragic love “The Sorrows of Young Werther” was a favourite, the poet William Wordsworth, the gothic novelist Clara Reeve whose most famous novel was “The Old English Baron” and the poems of Samuel Taylor Coleridge whose “Rime of the Ancient Mariner” she had heard the poet read aloud when a child.

John Milton’s influence is clear in the pages of “Frankenstein” where “Paradise Lost” also charts a complex story of creation. She references Shakespeare’s works several times in the novel particularly “The Tempest” and “Othello” and there is evidence she read Voltaire’s works “The Ingénu” and “Micromégas” which describe creatures from other worlds interacting with our own. Several of her father’s novels such as “The Adventures of Caleb Williams” were set in Switzerland like her own “Frankenstein”. The novel itself was inspired by a nightmare she had had at Geneva before the famous evening story telling session at the Villa Diodati.

She was also well aware of the scientific theories of the day in talking to her father, Shelley her Husband and Lord Byron and had heard of Giovanni Aldini’s experiments and Luigi Galvani’s theories on animal electricity who maintained that galvanism showed that “animal electricity” could create life. Due to this emphasis on the scientific ideas of the day she is seen as one of the founders of the genre of science fiction and is still admired as such today.

After the early death of her husband she devoted herself to promoting and editing the works of both Percy and her father and extending Godwin’s vision of gradual reform through education and discussion. After her own death she was chiefly known as the wife of Percy Bysshe Shelley and author of “Frankenstein” and her son’s well-meaning attempt to describe her life without the radical aspects did little to dissuade this view. Writings about her by Thomas Jefferson Hogg and Edward John Trelawny concentrated on her husband to the exclusion of her own genius and even her son’s wife edited her letters for publication in 1882 to try and show a quiet and almost timid character. It was not until the last quarter of the twentieth century that she began to be seen as an important figure in her own right.

The first theatrical production of “Frankenstein” was in 1823 and there have been many others since and film versions have been produced since the original in 1910. It is fair to say that they have influenced the horror genre in many ways from cheap shock to more cerebral interpretations. During the twenty first century the republication of almost all of her writing has shone a new light on its value and many authorities now consider her to be a major Romantic figure significant for both her literature and for her liberal political voice.
