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."
Gwendolen Mary John (22 June 1876 – 18 September 1939) was a Welsh artist who worked in France for most of her career. Her paintings, mainly portraits of anonymous female sitters, are rendered in a range of closely related tones. Although she was overshadowed during her lifetime by her brother Augustus John, her reputation has grown steadily since her death.
