Task: Question Answering
Input (English): Passage: In 1924, Rix Nicholas, again travelling with Dorothy Richmond, set sail for France, intending to exhibit her works in Europe. She voyaged on the Ormonde, which was also carrying the Australian Olympic team. She befriended several of the team members and painted a portrait of one for an Olympic artists' competition.Arriving in Paris in June, eventually Rix Nicholas rented a studio in Montparnasse, which had previously belonged to French artist Rosa Bonheur. An exhibition at the "prestigious" Georges Petit Galerie in Paris in January 1925 was a great success. It led to important sales, including to the Musée du Luxembourg, making her the only Australian woman to have more than one work in its collection and, according to one report, one of only three Australian artists represented at all at that time, the others being Rupert Bunny and Arthur Streeton. The exhibition led also to a tour of her works to London and British regional galleries, the first time any Australian artist had archived such prominence; between 1926 and 1928, her works were shown in Hull, Sunderland, Tyne and Wear, Bootle, Blackpool, Northampton, Warrington, Folkestone, Leicester, Derby, Gateshead and Leek in Staffordshire.The work purchased by the Luxembourg in 1925 was In Australia, a portrait of Ned Wright, manager of the property at Delegate where she had stayed in the early 1920s. He is portrayed on horseback, a pipe clasped in his exposed and bright teeth, with a panoramic backdrop of an Australian pastoral landscape. His stance is casual, self-assured and heroic, consistent with the up-beat nationalism of Australia at the time. 
Question: What is the last name of the only Australian woman to have more than one work in the collections at Musée du Luxembourg?
Output (English): Richmond.
