Love and Horror

During the summer of 1812, Shelley went to Scotland to stay with an acquaintance of her father William Baxter and his family. There she experienced a type of domestic tranquility she had never known. Shelley returned to the Baxters' home the following year.

In 1814, Mary began a relationship with poet Percy Bysshe Shelley. Percy Shelley was a devoted student of her father, but he soon focused his attentions on Mary. He was still married to his first wife when he and the teenaged Mary fled England together that same year. The couple was accompanied by Mary's stepsister Jane. Mary's actions alienated her from her father who did not speak to her for some time

Mary and Percy Shelley traveled about Europe for a time. They struggled financially and faced the loss of their first child in 1815. Mary delivered a baby girl who only lived for a few days. The following summer, the Shelleys were in Switzerland with Jane Clairmont, Lord Byron and John Polidori. The group entertained themselves one rainy day by reading a book of ghost stories. Lord Byron suggested that they all should try their hand at writing their own horror story. It was at this time that Mary Shelley began work on what would become her most famous novel, Frankenstein, or the Modern Prometheus.

Later that year, Mary suffered the loss of her half-sister Fanny who committed suicide. Another suicide, this time by Percy's wife, occurred a short time later. Mary and Percy Shelley were finally able to wed in December 1816. She published a travelogue of their escape to Europe, History of a Six Weeks' Tour (1817), while continuing to work on her soon-to-famous monster tale. In 1818, Frankenstein, or the Modern Prometheus debuted as a new novel from an anonymous author. Many thought that Percy Bysshe Shelley had written it since he penned its introduction. The book proved to be a huge success. That same year, the Shelleys moved to Italy.

While Mary seemed devoted to her husband, she did not have the easiest marriage. Their union was riddled with adultery and heartache, including the death of two more of their children. Born in 1819, their son, Percy Florence, was the only child to live to adulthood. Mary's life was rocked by another tragedy in 1822 when her husband drowned. He had been out sailing with a friend in the Gulf of Spezia.

Later Years

Made a widow at age 24, Mary Shelley worked hard to support herself and her son. She wrote several more novels, including Valperga and the science fiction tale The Last Man (1826). She also devoted herself to promoting her husband's poetry and preserving his place in literary history. For several years, Shelley faced some opposition from her late husband's father who had always disapproved his son's bohemian lifestyle.

Mary Shelley died of brain cancer on February 1, 1851, at age 53, in London, England. She was buried at St. Peter's Church in Bournemouth, laid to rest with the cremated remains of her late husband's heart. After her death, her son Percy and daughter-in-law Jane had Mary Shelley’s parents exhumed from St. Pancras Cemetery in London (which had fallen into neglect over time) and had them reinterred beside Mary at the family’s tomb in St. Peter’s in Bournemouth.

It was roughly a century after her passing that one of her novels, Mathilde, was finally released in the 1950s. Her lasting legacy, however, remains the classic tale of Frankenstein. This struggle between a monster and its creator has been an enduring part of popular culture. In 1994, Kenneth Branagh directed and starred in a film adaptation of Shelley's novel. The film also starred Robert De Niro, Tom Hulce and Helena Bonham Carter. Her work has also inspired some spoofs, such as Young Frankenstein starring Gene Wilder. Shelley's monster lives on in such modern thrillers as I, Frankenstein (2013) as well.
