Hermann Raab
Hermann Raab (born January 29, 1893 in Pirmasens ; † June 28, 1969 there ) was a German engineer and designer. He was married to Johanna Elfriede Henriette Birker from Wuppertal-Elberfeld, daughter of a civil engineer. The marriage had two children. Daughter Waltraut was born on May 22, 1924 and son Herbert on July 2, 1930.
Raab studied mechanical engineering at the Bingen technical center . Together with his fellow student Bernhard Rosemeyer , the father of racing driver Bernd Rosemeyer , he designed a 1 HP two-stroke engine . The two gave their small engine the name "The Little Miracle". The motor was realized in the father's machine factory Heinrich Raab in Pirmasens in 1914 as a bicycle auxiliary motor.
During the war, Bernhard Rosemeyer's financial situation worsened, as he was no longer able to reach transfers from his parents. Hermann Raab, deployed as a non-commissioned officer on the Western Front, then agreed to Rosemeyer's proposal to sell the engine to the Zschopau Rasmussen Works .
The Rasmussen-Werke (later DKW) built this small engine, which was ready for series production, in large numbers in the period after the First World War .
A rotary piston engine he developed in the 1920s never reached production readiness.
Until his death in 1969 he worked as an expert and representative for shoe machines and inventors in Pirmasens.
