Austrian architect Hans Pfann received Honorable Mention for his work Refinement of the Danube Island near Langenzersdorf together with his compatriot [Erwin Ilz] at the 1936 Berlin Olympics in the Art Competitions in the category Architecture, Designs For Town Planning. Pfann studied at the Technical High School in Wien (Vienna). His career started with town planning projects mainly in Wien and he later often worked with Ilz.

As an architect he built single-family homes in Austria and abroad, residential buildings, city regulations, engineering and industrial buildings, sports facilities and public buildings.
In 1941 Pfann was appointed professor for "Decorative art and garden art" at the Technical High School, and in 1954 professor for “Crafts, Interior Design, Garden Art and Architecture”. He then also installed an own institute for garden art.
