Olga Milles, née Granner (1874–1967), grew up in Graz, Austria. Already as a child, Olga showed artistic talent. She studied art in Munich and Paris, and alongside her studies she supported herself by painting portraits. She saw her future as a professional artist, preferably working in a convent, but everything changed when she met Carl Milles in Paris in the late 1890s.
The marriage to the man who would soon become one of Sweden’s most famous sculptors created unusual living conditions, but Olga always maintained her right to her own professional and private life. Carl constantly spoke of Olga as the only person whose artistic opinions he cared about. The Milles couple collaborated on one occasion when Olga Milles painted the large Gustav Vasa sculpture that Carl Milles created for the Nordic Museum.
Several of Olga’s artworks can be seen in the Artists’ Home at Millesgården, as well as two interior design details she created: the paintings on the cabinets in the breakfast room and the flooring outside the Red Room.
Olga helped establish a foundation and donated Millesgården to the Swedish people in 1936. After Carl’s death, Olga Milles spent her final years in Graz, where she died in 1967 at the age of 93. Olga Milles is buried at Millesgården.
