Hilda Rix Nicholas was an Australian artist. Born in the Victorian city of Ballarat, she studied under a leading Australian Impressionist, Frederick McCubbin, at the National Gallery of Victoria Art School from 1902 to 1905 and was an early member of the Melbourne Society of Women Painters and Sculptors. Following the death of her father in 1907, Rix, her only sibling Elsie and her mother travelled to Europe where she undertook further study, first in London and then Paris. Her teachers during the period included John Hassall, Richard Emil Miller and Théophile Steinlen.
After travelling to Tangier in 1912, Rix held several successful exhibitions of her work, with one drawing, Grande marché, Tanger, purchased by the French government. She was one of the first Australians to paint post-impressionist landscapes, was made a member of the Société des Peintres Orientalistes Français, and had works hung in the Paris Salon in 1911 and 1913. The family evacuated from France to England after the outbreak of World War I. A period of personal tragedy followed, as Rix's sister died in 1914, then her mother in 1915.
