Mary Shelley: Bisexuality, Heart Story & Nepo Baby Debate

Most people know Mary Shelley as the teenager who wrote Frankenstein, but her own life was stranger than any gothic novel — daughter of two famous radicals, she eloped at sixteen, lost three of her four children, and kept her husband’s preserved heart in a desk drawer for three decades. Here’s what fact and legend actually say about the woman behind the monster.

Parents: William Godwin, Mary Wollstonecraft ·
Spouse: Percy Bysshe Shelley (married 1816–1822) ·

Seven key facts, one pattern: Mary Shelley’s biography is a tangle of trauma, talent, and contested narratives.

What was unusual about Mary Shelley’s life?

Daughter of radicals

• Mary Wollstonecraft Shelley was born to two of the most famous radical writers of the 18th century: Mary Wollstonecraft, author of A Vindication of the Rights of Woman, and William Godwin, the philosophical anarchist (Poetry Foundation). Her mother died ten days after childbirth from complications (Poetry Foundation). Growing up in a household visited by poets, philosophers, and reformers shaped her intellectual world from the start.

Elopement with Percy Bysshe Shelley

• In July 1814, at just sixteen, Mary Godwin ran away to France with the married poet Percy Bysshe Shelley (Encyclopaedia Britannica). The scandal was enormous. Percy was still married to Harriet Shelley, and the couple faced social ostracism, debt, and a custody battle over Percy’s children. They married in December 1816, after Harriet’s suicide (Encyclopaedia Britannica).

The heart in the drawer

• When Percy Bysshe Shelley drowned in 1822 near Viareggio, his body was cremated on the beach. According to accounts, his heart did not burn and was retrieved from the pyre by his friend Edward John Trelawny (Bi.org). Mary Shelley kept the preserved fragment in a silk pouch inside her desk for the rest of her life (Bi.org). Some modern researchers suggest the organ may have been a calcified liver, but the heart story has become part of the Shelley legend.

The implication: Even the most macabre details of her life fed a creative output that defined a genre.

What is Mary Shelley most famous for?

Frankenstein; or, The Modern Prometheus

• In the summer of 1816, Shelley traveled to Geneva with Percy and her stepsister Claire Clairmont, staying near Lord Byron (Bodleian Libraries, University of Oxford). A now-famous ghost story challenge produced the nightmare that became Frankenstein. The novel was first published anonymously in 1818 (Encyclopaedia Britannica). It is widely considered the first work of science fiction (Encyclopaedia Britannica).

Other notable works

• Shelley published several other novels: Valperga (1823), The Last Man (1826), Perkin Warbeck (1830), and Lodore (1835) (Poetry Foundation). She also contributed biographical essays, travel writing, and short stories. Her late work often explored themes of isolation and political collapse.

The pattern: Her fame rests on one breakthrough, but her overall literary corpus is far richer than commonly acknowledged.

Is Mary Shelley a Nepo baby?

Parentage and early influence

• Her father, William Godwin, was a leading philosopher and novelist who ran a bookshop and publishing house (Duke University Libraries). Her mother, Mary Wollstonecraft, was the founding feminist writer of the era. The Godwin household was a literary salon that hosted Coleridge, Wordsworth, and Hazlitt, giving Mary access to the intellectual elite from childhood.

Her own literary merit

• Critics and biographers generally agree that Shelley’s success was earned by her own talent. She wrote Frankenstein at 18, crafted a novel that no one else could have written, and supported herself and her son through her writing after Percy’s death (Encyclopaedia Britannica). The “nepo baby” label oversimplifies a career built on rigorous self-education, relentless editing, and market savvy. Her father’s connections opened doors, but she walked through them by producing work that outlasted everyone in her circle.

What this means: The nepo label is reductive; her achievement stands on its own.

Did Mary Shelley have a female lover?

Evidence of same-sex relationships

• After Percy’s death, Mary Shelley formed intense emotional attachments to several women, most notably Jane Williams (Bi.org). Letters between the two express deep affection and longing. According to some modern biographers, Shelley wrote that she had only “sought romantic relationships with women” after her husband’s drowning (Bi.org).

Bisexuality in historical context

• The evidence is circumstantial. No explicit sexual acts are recorded, and the language of Romantic-era friendship between women was often passionate by modern standards. Many scholars now describe Shelley as bisexual or queer, but the label relies on interpretation rather than hard documentation (Bi.org).

The question remains open: the evidence is compelling but not conclusive.

Why did Shelley’s heart not burn?

The cremation of Percy Bysshe Shelley

• On 8 July 1822, Percy Bysshe Shelley drowned in the Gulf of Spezia (Encyclopaedia Britannica). Under Tuscan law, his body had to be cremated on the beach. The pyre was built near Viareggio, and as the flames consumed the corpse, something strange happened.

The heart that did not burn

• According to his friend Edward John Trelawny, Shelley’s heart remained intact and was rescued from the fire (Bi.org). Mary Shelley eventually obtained the relic and kept it in a silk pouch in her desk. After her death, the heart was found among her papers. Skeptics note that the organ could have been a calcified liver, but no forensic testing has been done.

The catch: Whether heart or liver, the relic encapsulates the mythic dimension of her life.

How many pregnancies did Mary Shelley have?

The table below outlines the tragic chronology of her pregnancies.

• Mary Shelley endured four pregnancies between 1815 and 1819. Her first child, a premature daughter, died within days (Poetry Foundation). Her son William died of malaria at age three (Salem Press). Clara Everina died in Venice at 13 months (Salem Press). Only Percy Florence Shelley survived to adulthood (Poetry Foundation). She also suffered a near-fatal miscarriage in June 1822 (Salem Press).

The pattern: Loss always shadowed her life and gave her fiction its enduring emotional weight.
