Painter, born in Glasgow, who spent most of his life there. After a short period in business after leaving school, Ewart attended Glasgow School of Art, his teachers including Maurice Greiffenhagen and Fra Newbery. On graduating in 1924, he used a scholarship to take him to Italy and France. On his return, in 1926 his picture The Emigrants was a great success at Royal Glasgow Institute of the Fine Arts show, a companion picture, The Return (now in the collection of Scottish National Gallery of Modern Art), appearing the following year. Ewart showed also at RA and RSA, where he won the Guthrie Award in 1926 and the Lauder Award in 1927. His work is notable for its hard-edged, ultra-realistic quality, very suited to the pictures of American tycoons and their wives which he painted during prolonged visits from the mid-1940s.
