When Augustus John died in 1961 he was described in The New York Times as ‘the grand old man of British painting and one of the greatest in British history.’ He was only in his mid twenties when, in the early 1900s, he was widely acknowledged as one of the most talented and promising young British artists – a Welsh rival, perhaps, to Gauguin or Picasso.
