Mary Wollstonecraft Shelley (UK: /ˈwʊlstənkrɑːft/; née Godwin; 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.
Shelley’s mother died less than a month 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.
In 1816, Mary with her husband and her stepsister 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. 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 the upbringing of her son and a 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 age 53.
