As the son of a postman and the first female master butcher in Vienna, Hans had a carefree childhood. As a trained clerk, he worked his way to the fine arts through piano and violin concerts.

Three-year degree at the university under Prof. Ferdinand Spiegel and first works for the large “Berliner Illustrierte” of Ullstein Verlag. Only a few works from this period survived the war. Among them many drawings in the Berliner Illustrierte.

War missions as a war correspondent directly at the front line stayed with Liska for the rest of his life. After successfully avoiding conscription into the Wehrmacht for many years, he was drafted into the propaganda unit in 1940. For many years he was flown to all major front lines all over Europe and processed what he saw for many subsequent years.

Liska experienced the last months of the war in Stübig near Bamberg. His company was evacuated from Berlin by the invading occupation forces. Thanks to his self-sufficient status, he was initially housed in an inn and escaped captivity. Liska, who was never a member of the NSDAP, was immediately acquitted of all allegations of complicity.

After the war Scheßlitz became his new home, where he met his wife Lisl and married her soon after. He lived and worked here for the rest of his life and had two daughters.

During the years following the war Liska worked with many large illustrated magazines like the newly founded 'Quick' and other large illustrated magazines and newspapers. With his colourful imagination he gave life to many futurist visions and inventions.

Years of collaboration with Daimler-Benz during the 1950s shaped Liska's artistic portfolio. Liska became known internationally through the impressive display of rapid technology and its speed.

As a sought-after graphic designer, Liska designs advertisements for many well-known German companies, including Kaufhof-AG, Degussa, Märklin, Quelle, Farbwerke Hoechst, Mülhens (4711) and the Henkell Sektkellerei. But also local companies such as the Schlenkerla smoked beer brewery in Bamberg were among his customers.

Liska published large parts of his Home in several Illustrated books.
