Albert Müller (29.11.1897, Basel - 14.12.1926, Obino) made an impressive contribution to Swiss Expressionism with his paintings, sculptures, watercolours, drawings and prints. From 1913 to 17 he completed an apprenticeship as a glass painter and attended the general trade school in Basel. In the summer of 1918 he stayed with Cuno Amiet on the Oschwand, where Müller abandoned his traditional dark-toned style and achieved an expressive use of colour. At the Christmas exhibition of 1919 at the Kunsthalle Basel Müller drew attention to himself for the first time. 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 an intense artistic friendship developed. In 1924 Müller founded the artist group Rot-Blau together with Hermann Scherer and Paul Camenisch. In 1926 Müller died unexpectedly in Obino at the age of only 29, whereupon Kirchner set up a memorial exhibition for him in the Kunsthalle Basel in 1927.
