Carl Milles was a Swedish sculptor born in Lägga. He studied at the Technical School in Stockholm, at the Ecole des Beaux-Arts in Paris under Auguste Rodin and on study trips to Germany, the Netherlands and Belgium. In Paris he came to stay for many years and made a living as an ornament carver. He studied the animals in the Jardin des Plantes (the Zoological Garden) and was strongly influenced by Auguste Rodin. Milles made a breakthrough with a monument to Sten Sture in Uppsala. He exhibited at the World's Fair in 1900 and was later given a solo exhibition at the Tate Gallery in London. Milles was professor of modeling at the Royal Academy of Arts in Stockholm. Well-known sculptures in public places signed by Carl Milles are the "Gustav Vasa" statue at the Nordic Museum, "Orfeusgruppen" outside the concert hall in Stockholm and the "Poseidonfontänen" in Gothenburg.
