As a student at the Academy of Fine Arts Munich (Akademie der Bildenden Künste), he received numerous awards and participated in joint exhibitions as a member of the Arbeitsgemeinschaft Pfälzer Künstler,[2] an organisation of Palatinate Artists.
In addition to Alfons Zeileis, de:Egon Adler (painter), who was close to Der Blaue Reiter, the Rhineland Expressionist Carlo Mense, the graphic artist Walter Rehn and the American painter Albert Bloch, who was also close to Der Blaue Reiter, took part in this exhibition.
In the summer of 1916, Alfons Zeileis was appointed as a drawing teacher at the "Realanstalt am Donnersberg", today's Gymnasium Weierhof.
[3] After the war, he worked as an assistant at the Progymnasium Homburg and then as a teacher at the Kurfürst-Ruprecht-Gymnasium Neustadt an der Weinstraße.
As a member of the Palatinate Artists' Association (Arbeitsgemeinschaft Pfälzer Künstler), he took part in numerous exhibitions from 1926 to 1930, which are listed on the German Wikipedia page de:Alfons Zeileis.
Despite his difficult living situation, he took part in exhibitions organised by the Palatinate Artists' Working Group again from 1948.
On October 18, 1927, for example, the Rheinpfälzer wrote about the art exhibition in Landau: "The talented Alfons Zeileis would get lost in the Kokoschkaian confusion with his painting Stubaital.
For him, nature also came to life through clouds; his skies are always moving, whether bright or in a melancholy, gloomy mood, such as the tree painting from his early years.
Zeileis was connected to nature in an almost mystical way, to the landscape in its vastness or density, to the lush blooms on the doorstep.
He painted what he saw, but he did not depict: "He made visible what his senses recognised in nature through the veil of his soul" (E.A.Poe)' Alfons Zeileis left behind an extensive body of work in his estate.
