Anecdotes
In the summer of 1816, Claire Clairmont stayed with Mary and Percy Shelley near Lake Geneva, very close to the Villa Diodati rented by Lord Byron. It was during those rainy evenings, when the group challenged one another to write ghost stories, that Mary Shelley conceived *Frankenstein*.
It was Claire who, first among the circle, wrote to Lord Byron to meet him, and not the other way around. From this affair a daughter, **Allegra**, was born in **1817**; Byron agreed to acknowledge her but refused to let her be raised by her mother.
Byron placed little Allegra in a convent near Ravenna, despite Claire's desperate protests. The child died there of fever in **1822**, at only five years old — a loss that haunted Claire for the rest of her life.
To earn a living, Claire worked for years as a governess and tutor, notably in Russia in Moscow, far from the romantic turmoil of her youth. She was fluent in several languages.
Having lived to the age of 80, Claire outlived nearly the entire Romantic circle. Toward the end of her life in Florence, admirers sought to buy from her the letters of Shelley and Byron that she had kept — a situation that inspired Henry James's novella *The Aspern Papers*.
