Dübi-Müller was exceptionally well connected within Swiss and international artistic circles, and she collected works by Cézanne, van Gogh and Klimt, as well as Cuno Amiet and Ferdinand Hodler. As a photographer, she documented the lives of artist friends as well as her own experiences, including journeys across Europe and as far as North Africa. Whether mountaineering, motor racing or collecting art, Gertrud Dübi-Müller refused to be constrained by gender stereotypes and lived with remarkable independence for a woman of her time. Artists: Cuno Amiet, Alice Bailly, Hans Berger, Georges Braque, Paul Cézanne, Giovanni Giacometti, Juan Gris, Ferdinand Hodler, Gustav Klimt, Fernand Léger, Max Liebermann, Henri Matisse, Pablo Picasso, Albert Trachsel, Félix Vallotton, Vincent van Gogh
