RESUMO
At the start of the First World War, the estate of Cliveden was offered as a hospital to the Canadian Government by its owner William Astor. This article describes its history, Sir William Osler's involvement in the hospital, and the involvement of other doctors and some of their research. The rehabilitation programs to help the injured soldiers are described, including the physical, occupational, sporting and social activities undertaken in order to help them towards their return to civilian life. Political ambitions in Canada and friction between the owner of Cliveden, Nancy Astor, and the medical/military establishment led to turmoil which engulfed Osler and is known as the 'Taplow Affair'. The hospital was dismantled after the war but became re-activated in the Second World War and is now a National Trust property.
