Franz Xaver Reimspieß was remarkable for his precise work and his wealth of ideas.
For the Auto Union P racing car Reimspiess designed new brakes and altered the rear axle to shaft suspension.
During the war Reimspieß was chief designer at the tank development centre within the Nibelungen plant at St Valentin.
At Porsche Reimspieß patented around ten inventions for the independent wheel-suspension system and for engines.
However, competing claims assert that the logo was created by graphic designer Nikolai Borg or the German artist Martin Freyer.
