Mary Wollstonecraft Shelley (1797–1851) is best known as the author of 'Frankenstein'. Her mother was the pioneering feminist Mary Wollstonecraft and she was unusually well-educated and free-thinking women for her time. She married the poet Percy Bysshe Shelley. Her famous novel 'Frankenstein' was conceived during a contest to write ghost stories, when she was staying with Shelley, Lord Byron and friends. After her husband’s death she became a professional writer, producing plays, short stories, novels and travel books, as well as promoting her late husband’s work. She died in 1851 aged 53.
