Hellmuth Hirth founded Hirth Motoren in 1927. Hirth aircraft engines were well-known for their excellent engineering and high quality. Herr Hirth was killed in an aircraft crash in 1938 and the German government took control of the company.
After World War II, Hirth Motorenwerke built small two-stroke engines. The company ran into problems in 1974 due to the oil crisis.

Hans Göbler acquired the company renaming it Göbler-Hirthmotoren. A reviving ultra-light market allowed the company to re-enter the aircraft engine market.
