The son of a French wine importer and his German wife, Claude Dornier was born in Bavaria where he grew up and attended school, with science being his chief interest. Dornier then moved to Munich, where he graduated in 1907 from the Technical University. His grandson, Iren Dornier also followed a career in aviation as a pilot and also a majority controller of a regional airline in the Philippines called South East Asian Airlines. His grandson Iren also flew a world-tour in dedication to his fathers adventures using a refurbished Do-24TT, the funds all went to charity in the Philippines (Philippine UNICEF) and other developing nations.
As a young engineer he first worked on strength calculations at Nagel Engineering Works in Karlsruhe. In 1910, he joined Luftschiffbau Zeppelin in Friedrichshafen on the Bodensee, where his advanced abilities quickly attracted count Ferdinand von Zeppelin's attention. Soon appointed as the count's personal scientific advisor, Dornier began fundamental research and design on improving the strength of light metal sections and later on aircraft engineering and giant metal flying boats.
Dornier is also recognised in the history of German aviation for his unique propeller design. His planes often featured double ended props on the front and the back of the planes in a push-pull configuration. This added to the overall maneourvability of the aircraft, with some of them reaching up to 600mph.
