Ludwig Hausfelder (1890-1964)
"WE regret to announce the death of Dr. Ludwig Hausfelder who contributed after the war many articles to THE ENGINEER on diesel engine and automobile subjects. He died in London on November 10th.
Dr. Hausfelder belonged to that generation which was predestined to experience the direct, and indirect, impact of two world wars. His professional career as an engineer was thrice interrupted by the First World War, in which he participated, by emigration to England in 1933 and then by internment during the second war. He bore these blows of fate with a remarkable equanimity, and without bitterness or resentment, establishing himself again, with unbroken spirit, after each interruption under progressively increasing difficulties.
Born 1890 in Breslau he was educated at a neo-humanistic school, and after one year's apprenticeship, studied mechanical engineering at the Technical Universities of Danzig and Breslau. He graduated in 1913 as a Dipl.-Ing. His first appointment was with the N.A.G. in Berlin.
In 1914 he volunteered for the German Air Force, became a pilot and was commissioned. In 1919 he resumed work with the N.A.G., and then joined an Italian firm, Brevetti-Baguto in Turin, as development engineer. In 1924 he returned to Berlin and became consultant for diesel engines with Deutsche Werke, Kiel, later with Motorenwerke Deutz, Motoren Werke Mannheim (formerly Benz) and, finally, Daimler-Benz, Gaggenau. During this period he published articles in Z. V.D.l. and A.T.Z. and other motor-technical periodicals. Probably his most valuable technical publication was a book published in 1929 by M. Krayn-Kompressorlose Diesel Maschinen (Diesel Engines without Compressors), a comprehensive survey of patented developments in the field of airless fuel injection which is a very valuable, critical and historical review, not only of constructions which had already proved their practical feasibility, but also of projects and ideas which have decisively influenced and shaped the art.
In 1929 he gained the degree of Doctor of Engineering (Dr.-Ing.), with a dissertation dealing with the reserve current supply of electrical power plants, especially those equipped with diesel engines. This dissertation was published in 1930 in Technik und Wirtschaft. His contractual engagement with Daimler-Benz lasted until 1937, although he emigrated to England in 1933. In 1937 he joined Sir Dennis Burney as a designer of ship's engines and, from 1944 to 1947, he was engaged by Broom and Wade Ltd., High Wycombe, on the development of compressors. As a consultant and technical writer with an unflagging devotion for, and interest in, internal combustion engines and motor cars, he remained contemporary to the end. His friends will cherish his memory as that of a man of great professional and personal integrity, and of an engineer who combined a sound basis of theoretical knowledge with a vast amount of practical experience.
