Heinrich Dubbel

from Wikipedia, the free encyclopedia

Heinrich Dubbel (born April 8, 1873 in Aachen , † May 24, 1947 in Berlin ) was a German professor of mechanical engineering and the initiator of the standard work paperback for mechanical engineering named after him and still widely regarded today .

life and work

Heinrich Dubbel was born the son of an engineer who owned a factory in Aachen. He studied mechanical engineering at the Technical University in Aachen (today RWTH ) and then gained international experience in Ohio in the USA. He then worked as a designer in his father's company. From 1899 he taught at mechanical engineering schools, from Cologne via Aachen, Essen and then from 1911 at the Berlin Beuth School , where he received the title of professor after another five years. Due to political differences with the National Socialist authorities, he resigned from the public service in 1934 and was then primarily active in advising Springer Verlag in the field of mechanical engineering. He wrote several essays and books, especially on the subject of steam engines and turbines, oil and gas machines, but also on factory operations.

Shortly before his death, he wrote the following foreword for a shortened edition of the paperback as a "makeshift" from Springer-Verlag, Berlin-Charlottenburg, Jebensstrasse 1:

“Since military measures were primarily aimed at industrial plants, a large part of the technical literature has been lost for this reason alone. Quite apart from the destruction of large printing works that are particularly suitable for the production of technical books, it is above all the scarcity of paper that makes it difficult to replace the destroyed literature and in particular prevents new editions of larger works such as the 'paperback for mechanical engineering'. Since for this reason the early production of the long overdue tenth edition was out of the question, the publisher decided to use the makeshift solution proposed by the editor, which contains the formulas, tables of numbers and sentences most important for mechanical engineers Simplifies the engineer's calculations and frees up his memory. For the student, the content should be a guide in important subjects. The solution to the given problem excluded the reproduction of constructions, which would have increased the already existing difficulties of production and the time of the publication of the little work would have been postponed. But the main thing here was that if you help quickly, you help twice. A little book like this one will always have gaps: may one stick to what it contains and be lenient about what is missing. "
