Friedrich Sauthoff

Friedrich Sauthoff (born May 28, 1905 in Osnabrück ; † December 23, 1994 in Düsseldorf ) was a German mechanical engineer .

Live and act

Sauthoff, grandson of Moringer city chamberlain Heinrich Sauthoff , studied from 1923 to 1928 at the Technical University in Berlin-Charlottenburg and completed from 1929 to 1932 trained as State Railroad builder. In doing so, he examined the driving resistance of railroad cars and trains at Hans Nordmann's . With the resulting dissertation The Resistance to Movement of Railway Cars with special consideration of the more recent tests of the Deutsche Reichsbahn , Sauthoff was awarded a Dr.-Ing. In 1932 at the Technical University Berlin-Charlottenburg. PhD . The main result of these investigations was Sauthoff's resistance formula , which was used until the 1980s.

After completing his doctorate, Sauthoff entered the service of the Deutsche Reichsbahn and from 1934 worked in the braking test department at the Reichsbahn repair shop in Berlin-Grunewald, which later became the test office for brakes of the Reichsbahn-Zentralamt Berlin, of which he became head in 1941. Due to the war, the Brake Testing Office was evacuated to Glogau / Silesia in January 1944 and to Göttingen / Lower Saxony in February 1945. After the Second World War it was assigned to the new Federal Railroad Central Office in Göttingen, with which it was relocated to Minden / Westphalia in 1951. The office continued to be headed by Sauthoff, who, as an expert for railway brake technology and in particular railway air brakes, participated in international technical committees and contributed to Lueger's lexicon of all technology . The Sauthoff formula and the Minden braking distance equation (1961) also go back to him. His publications were primarily devoted to railroad training.

From 1963 until his retirement in 1970, Sauthoff headed the department responsible for braking technology at the Minden Federal Railway Central Office . His services were recognized in 1972 by the award of the Federal Cross of Merit 1st Class and in 1987 by the Beuth Medal of Honor of the German Machine Technology Society DMG "in appreciation and grateful recognition of his great services in researching the aerodynamics and driving resistance of rail vehicles".
