Share
Mary Shelley was born Mary Godwin in London in 1797. She was the daughter of philosopher William Godwin and feminist writer Mary Wollstonecraft, who died shortly after her birth. At age sixteen, she eloped with poet Percy Bysshe Shelley, whom she married in 1816 after his first wife's death. Shelley began writing *Frankenstein; or, the Modern Prometheus* in 1816 during a summer in Switzerland, where she lived near Lord Byron. The novel was published anonymously in 1818 and became her most celebrated work. It is regarded as a foundational science fiction novel and remains widely read and studied. The book explores themes of ambition, responsibility, and the consequences of scientific advancement. Following Percy's death by drowning in 1822, Shelley supported herself and her son through writing. She produced numerous other works, including novels such as *The Last Man* (1826) and *Lodore* (1835), as well as short stories, essays, and editions of her husband's poetry. Shelley's literary output was substantial and varied, yet *Frankenstein* overshadowed her other achievements during her lifetime and continues to define her legacy. She died in London in 1851 at age fifty-three. Her influence on literature and popular culture has been profound and enduring. *Frankenstein* established conventions of science fiction and remains a central text in discussions of the genre. Shelley's exploration of scientific ethics and human responsibility continues to resonate with contemporary readers and writers.
