Steyr

Steyr (or Steyr-Puch) was an Austrian automotive company from 1915 until 1990.

Formed as a branch of Steyr Osterreichische Waffenfabriks-Gesellschaft (Steyr AG) in 1915, to diversify manufacturing, the founders hired 38-year-old designer Hans Ledwinka after he resigned from Nesselsdorfer-Wagenbau. Ledwinka developed Steyr's new six-cylinder car and supervised hiring engineers and mechanics.
