Wolfgang Klemperer published test results showing the advantages of Paul Jaray’s aerodynamic automobile bodies. Jaray, of Hungarian-Jewish descent, was born in Vienna in 1889. He learned streamlining while designing airships in the wind tunnel of the Zeppelin Company. In 1923 he moved permanently to Switzerland opening an office. In 1927, Jaray founded the Stromlinien Karosserie Gesellschaft, which presented numerous designs for streamlined car body work. It issued licences to major vehicle manufacturers including Tatra Works in Czechoslovakia. Tatra was the only manufacturer that introduced Jaray streamlining principles into their car production, for instance, the Tatra 77.
