Ruth Milles, née Andersson (1873–1941), was Carl’s older sister and grew up at Örby Gård outside Uppsala.
She showed artistic talent early on, studied at the Technical School and the Royal Academy of Fine Arts, and then travelled to her brother in Paris to study sculpture at Académie Colarossi and École des Beaux-Arts. Despite limited finances, she lived for her art and supported herself as an illustrator.
When Ruth’s health declined, she returned to Stockholm and quickly established herself as a sculptor. She created busts and medallions and received commissions from the Royal Dramatic Theatre (Dramaten). Her works were exhibited internationally, including in Buenos Aires where she was awarded a silver medal, and her sculptures were purchased by the Nationalmuseum. Ruth’s art was characterized by national romanticism, mysticism, and a love of nature.
Despite her own successes, she chose to highlight her brother Carl in her unpublished memoir notes from 1923, where she saw it as her duty to tell the story of his career. In 1932, Ruth moved to Rome, Italy. There she wrote and illustrated fairy tales for collected editions.
Ruth died in Rome in 1941 and is buried in the Protestant cemetery in the city.
Several works by Ruth Milles can be seen in the Artists’ Home at Millesgården.
