Albert Müller (1897, Basel – 1926, Obino in the Muggio Valley) made an impressive contribution to Swiss Expressionism with his paintings, sculptures, watercolours, drawings, and prints. From 1913 to 1917 he completed an apprenticeship as a glass painter and attended the general trade school in Basel. During the summer of 1918, he stayed with Cuno Amiet on the Oschwand, where Müller overcame traditional dark-toned styles and grew into a colourful Expressionism. Müller initially attracted attention at the 1919 Christmas exhibition in the Kunsthalle Basel. In 1920, he travelled to Italy and worked with Niklaus Stoecklin in San Gimignano. In 1923, Müller met the expressionist Ernst Ludwig Kirchner. In the following years he was a frequent guest of Kirchner in Davos and subsequently an intense professional friendship developed. In 1924, Müller founded the artists’ group Rot-Blau together with Hermann Scherer and Paul Camenisch. In 1926, Müller died unexpectedly in Obino at the early age of 29, whereupon Kirchner set up a memorial exhibition for him in the Kunsthalle Basel in 1927.
