His father, Franz Komenda, was the technical director of the first power station on the Semmering and in Weyer / Enns, where the family relocated in 1913.
Here he met Ferdinand Porsche for the first time, who came to Steyr as Technical Director after leaving Daimler-Benz AG.
From 1929 to 1931 he was chief designer of the experimental and body development department of Daimler-Benz AG in Sindelfingen.
With graduate engineer Josef Mickl, a Porsche employee specializing in aircraft construction and aerodynamics, Komenda developed the bodywork of the P-Auto Union racing car and Cisitalia racing car.
As early as 1946 Komenda began work on the body of the first Porsche sports car.
