Until the age of 9, he showed normal development and attended a special school. After that, no teaching or job could be found for him. At age 16, he first entered in-patient psychiatric treatment, where he remained until age 20. He returned to psychiatry at age 36 when his mother fell ill.
Walla worked very artistically as a draftsman, painter and photographer. In his art, he captured his surroundings by painting invented and existing symbols as well as godlike creatures on objects (even on houses or trees). Figures and symbols can be found in all his works. He created a complete artistic cosmos. August Walla lived in the House of Artists in Maria Gugging since 1983 and was one of the most versatile artists of the so-called "Art Brut".Wikipedia
