In the summer of 1816 he settled at the Villa Diodati by Lake Geneva, Switzerland, with his personal physician, the young, brilliant and handsome John William Polidori. There Byron befriended the poet Percy Bysshe Shelley, and Shelley's future wife Mary Godwin. He was also joined by Mary's stepsister, Claire Clairmont, with whom he had had an affair in London. Several times Byron went to see Germaine de Staël and her Coppet group, which turned out to be a valid intellectual and emotional support to Byron at the time.
