Claude Barry (16 December 1883 – 25 October 1970), later calling himself Francis Barry, was a British etcher and painter in oils who often used a pointillist style or a limited palette of flat colours.
From 1900 Barry studied at Bournemouth Art College and then privately with Sir Alfred East, who was a friend of the family. In 1905 Barry followed East to Newlyn in Cornwall, where a colony of artists had been formed. There Barry also studied with the artist Stanhope Forbes. Barry later moved to St Ives, where another colony of artists had formed after Newlyn became too industrial, and he became involved in the St Ives Society of Artists. Barry was elected to the Royal Society of British Artists in 1906, when Alfred East was its President.
Barry was influenced by Frank Brangwyn, who used broad blocks of colours to show light and shade. Barry claimed that Brangywn taught him to reduce his palette of colours to seven tones, four of light and three of shadow. Barry developed a Pointillist style, made famous in the late 19th century by Georges Seurat, and applied bright contrasting oil colours to create forms and shades, or used large flat blocks of a few complementary colours to create shapes and contrasts on large canvasses.
