Before moving to Swansea, Murray was Art Headmaster of West Bromwich Municipal School of Art for three and a half years. While being interviewed for the position of principal of Swansea Municipal School of Art in 1908, Murray told the interviewing panel: He told them that the Art School was the most dismal that he had ever seen, the rooms were too small and the lighting was bad. As far as he could see, their Art School was as good as dead and he had no desire to be associated with the inevitable funeral! He was appointed on the first ballot. On his appointment he was the only teacher for 107 part-time students. Under his leadership the school grew rapidly in scope and reputation. In 1910 the Art School was ranked 140th in England and Wales; by 1914 it was in 25th place. In 1925 the school won a Grand Prix at the International Exposition of Modern Industrial and Decorative Arts in Paris. In 1939 it had 530 students. Murray introduced stained glass making in the art school in 1935. It has since developed into a major centre for artistic glass. He retired in 1943, after 34 years as principal.
In 1911, two years after becoming principal of Swansea Art School, Murray was asked to become curator of the new Glynn Vivian Art Gallery in Swansea. He accepted, providing that an assistant was appointed at the school, and held both posts concurrently. The gallery was financed by the art collectorRichard Glynn Vivian, who provided his collection of paintings, drawings and china. Building on Richard Glynn Vivian's collection, Murray expanded the gallery's collection by acquiring works by established painters such as Augustus John, Gwen John and James Dickson Innes; and younger painters including Kyffin Williams and John Elwyn. Murray played a leading part in the acquisition for Swansea of the British Empire Panels by Frank Brangwyn. These sixteen large panels had been commissioned in 1927 for the Royal Gallery at the House of Lords as a memorial to the dead of the First World War, but they were rejected as unsuitable for the Palace of Westminster. They were installed in the Brangwyn Hall Swansea in 1934, where they remain. Murray remained curator of the Glynn Vivian Art Gallery until his death in 1950.
