In later life, John wrote two volumes of autobiography,
Chiaroscuro (1952) and
Finishing Touches (1964). In old age, although John had ceased to be a moving force in British art, he was still greatly revered, as was demonstrated by the huge show of his work mounted by the
Royal Academy in 1954. He continued to work up until his death in
Fordingbridge, Hampshire in 1961, his last work being a studio mural in three parts, the left hand of which showed a
Falstaffian figure of a French peasant in a yellow waistcoat playing a
hurdy-gurdy while coming down a village street. It was Augustus John's final wave goodbye. He joined the
Peace Pledge Union as a
pacifist in the 1950s, and was a founder member of the
Committee of 100. On 17 September 1961, just over a month before his death, he joined the Committee of 100's's anti-nuclear weapons demonstration in
Trafalgar Square, London. At the time, his son, Admiral Sir
Caspar John was
First Sea Lord and
Chief of Naval Staff. He died at Fordingbridge, aged 83. He is said to have been the model for the bohemian painter depicted in
Joyce Cary's novel ''
The Horse's Mouth'', which was later made into a
1958 film of the same name with
Alec Guinness in the lead role.
Michael Holroyd published a biography of John in 1975 and it is a mark of the public's continued interest in the painter that Holroyd published a new version of the biography in 1996. A major exhibition, 'Gwen John and Augustus John,' was held at
Tate Britain over the winter of 2004/5. According to the gallery's publicity, this exhibition revealed 'that although Augustus described himself and his sister as "the same thing, really," their art developed in different directions. Augustus' work seems wildly exuberant against Gwen's more introverted approach, but both artists indicate a similar flight from the modern world into a realm of fantasy. The exhibition went on to the National Museum of Wales in Cardiff later in 2005. In 2018
Poole Museum in Dorset hosted the exhibition 'Augustus John: Drawn from Life,' which then went on to
Salisbury Museum in 2019. ==Honours and reputation==
