Augustus Edwin John OM RA (4 January 1878 – 31 October 1961) was a Welsh painter, draughtsman, and etcher. For a short time around 1910, he was an important exponent of Post-Impressionism in the United Kingdom."Augustus was celebrated first for his brilliant figure drawings, and then for a new technique of oil sketching. His work was favourably compared in London with that of Gauguin and Matisse. He then developed a style of portraiture that was imaginative and often extravagant, catching an instantaneous attitude in his subjects."
