Edward Robert Hughes RWS (5 November 1851 – 23 April 1914) was an English painter who worked prominently in watercolours, but also produced a number of significant oil paintings. He experimented with ambitious techniques and was a perfectionist; he did numerous studies for many of his paintings, some of which turned out to be good enough for exhibition.
E.R.Hughes is widely known for his works Midsummer Eve and Night With Her Train of Stars yet he built a career as a portrait painter to the upper classes. (Wikipedia.org) (theworldsartist.com)
