Cannan was living in 1916, and which attracted a number of his intellectual circle (including Lawrence and his wife Frieda, and Katherine Mansfield and John Middleton Murry). The picture also shows the Cannans' two Newfoundland dogs, Sammy on the left and Luath, who was also Barrie's dog before his divorce from Mary Ansell and the inspiration for Nana, the Darling children's nurse in Peter Pan. In 1916, partly in response to the devastating effects of the war and the threat of conscription, Cannan suffered a mental breakdown, an experience which he vividly described in his book, The Release of the Soul. His marriage ended in 1918 when he had an affair with Gwen Wilson who later married Henry Mond in 1920 while Cannan was lecturing in the United States. Unconventionally, Cannan lived with Wilson and her new husband in a ménage à trois in their home, Mulberry House, in Smith Square, Westminster. After the war Cannan devoted himself to writing, translation work and travel but another mental breakdown in 1923 proved untreatable. He became a mental patient at the Priory Hospital, Roehampton. He then spent the rest of his life confined to Holloway Sanatorium near Virginia Water where he died of cancer on 30 June 1955. Family The poet May Wedderburn Cannan and her sister, the writer Joanna Cannan, were cousins of his, daughters of the academic Charles Cannan (Dean of Trinity College, Oxford, and Secretary to the Delegates of Oxford University Press); as was Professor Edwin Cannan, the noted LSE economist (and brother of Charles Cannan); Joanna's daughter Diana Pullein-Thompson was his biographer. Joanna Cannan's son, Denis Cannan, also followed in his footsteps, becoming a dramatist in his own right.
