Aloys Wach was born on April 30, 1892 in Lambach. He decided to become an artist from an early age on and started his education at the private painting school Knirr und Sailer in Munich. During this time he met the graphic artist Jacob Steinhardt in Berlin and got to know the newly opened Der Sturm-Galerie. He attended the Colarossi Academy in Paris, where he met some painters at Le Bateau-Lavoir. His works from this period include expressionist-cubist drawings, etchings, and woodcuts. In 1919 he moved to Braunau am Inn. He also created expressionist still life, landscapes, and portraits. Wach participated in the development of the Innenviertler Künstlergilde. Later, he devoted himself to more religious themes and among other things, created glass windows for the hospital church in Braunau around 1930/1933. A collection of his works is exhibited in the Duke in Braunau. Aloys Wach died on April 18, 1940 in Braunau.
