Scottish artist Ellen May Murray Thomson (1889–1984) produced paintings and decorative designs in the Art Nouveau style in the 1910s. In 1917 she married artist John Murray Thomson RSA. Ellen was daughter of John Rose Frew, a master watchmaker and Provost of Dingwall (1906–1911), and a portrait she did of her father is in the collection of Dingwall Museum. It appears that before Ellen married she was a commercial artist and illustrator, producing designs inspired by architectural ornament, and creating decorative works in the Art Nouveau style—including commissions for ceramics. Thomson lived in Edinburgh (John teaching at the Edinburgh College of Art) and her floral designs were produced in the decade just following that of Charles Rennie Mackintosh's influential work in Glasgow. Ellen Murray Thomson also collaborated on children's book projects with her husband.
