Broncia Koller-Pinell (25 February 1863 – 26 April 1934) was an Austrian Expressionist painter who specialized in portraits and still-lifes.

[1] In 1870, they moved to Vienna to start a manufacturing business (where they changed the family name to "Pinell") and she took private art lessons with Alois Delug.

Shortly after, she set up a salon[4] that was frequented by Egon Schiele, Anton Faistauer and Albert Paris Gütersloh, among others.

In 1907 she painted a portrait of her closest painter colleague Heinrich Schröder, and in 1908 and 1909 she took part in the Klimt Group's art show.

After the First World War, Koller-Pinell maintained close artistic contact with Anton Faistauer, Albert Paris Gütersloh, Heinrich Schröder, Carl Hofer and Franz von Zülow.

In 1924, the German painter Carl Hofer visited Oberwaltersdorf and painted a portrait of Broncia (now in the Belvedere Collection).

Koller-Pinell was represented with eight works alongside Helene Funke, Maria Cyrenius, Elfriede Miller-Haunfels and others.

On the occasion of her death, Heinrich Schröder wrote to her daughter Silvia Koller: “It is a consolation to know that her life was extremely gifted, even if the world, especially the artists in Vienna, could not grasp her value.

Her work was included in the 2019 exhibition City Of Women: Female artists in Vienna from 1900 to 1938 at the Österreichische Galerie Belvedere.
