Katharina Schellenberger (born 1978 in Schweinfurt, Germany) studied art at the Accademia di Belle Arti in Rome, Italy. After her state examination in dentistry and a doctoral thesis on schizophrenia, both in Munich, Germany, she has been working professionally as a freelance artist in her studios in and near Munich since 2007. In addition to numerous nominations, she received the Valentine Rothe Award (1st place) from the Women's Museum in Bonn in 2009. In 2011 one of her paintings was purchased by the Bavarian State Painting Collection. She was admitted to the GEDOK (Association of Professional Women Artists) in 2012, and to the BBK (Association of Professional Visual Artists) in 2013. In recent years, she has increasingly exhibited in galleries internationally, including a solo exhibition in Venice, Italy, in 2016. She is a founding member of the KNOT Artist Collective, which was formed in 2019. In addition, her works have been shown in France, England, the Netherlands, Denmark, Sweden, Norway and America, as well as in major museums in Germany, such as the Buchheim Museum in 2020/2021.

Her painting oscillates between figuration and non-objectivity, between intuitive and cognitive perception. Instead of sketches, Katharina Schellenberger notes down everything relevant in her diaries in order to start a painting directly without any preliminary drawing on the painting surface. This systematic approach sharpens her perception of the reality of life. All formats are created in a single work process, often series emerge. In terms of content, Katharina Schellenberger deals in the broadest sense with the manifestations of transcendence. It is symbolically about the immersion and growth in spiritual worlds, about the transitions of life stages or between inner and outer world, about parting and letting go, but also about being held and passing on their own energies to others. The insecurity of existence and the fragility of the mind are supporting pictorial themes alongside self-irony paired with grotesque elements. Katharina Schellenberger's works are dedicated to the human condition in all its psychological and physical manifestations.
