Emil Josse (born January 7, 1866 in Darmstadt ; † March 31, 1940 in Berlin ) was a mechanical engineer and rector of the Royal Technical University of Berlin -Charlottenburg (today TU Berlin ). As a Prussian civil servant, he held the title of a secret councilor.
Scientific career
Emil Josse worked as a private lecturer from 1894 and in 1896 became head of the newly established machine laboratory, which was located at the university's heating and power station. From October 1, 1896, he taught steam engine construction as a full professor and the examination of machine systems in the department of mechanical engineering. His chair at the Königlich Technische Hochschule zu Berlin (from 1919 Technische Hochschule zu Berlin) was located in Department III (from 1922 Faculty III for Mechanical Engineering, from 1928 renamed Faculty III for Mechanical Engineering). His initially broader teaching assignment was later specified more precisely for power generation (heat and power management). In the academic years 1898/1899, 1910/1911 and 1911/1912 and finally in 1931/32 Josse worked as dean of the Faculty of Mechanical Engineering (mechanical engineering, electrical engineering, shipbuilding, aircraft construction). Before the First World War , Josse was also rector of the Royal Technical University of Berlin in 1912/1913. Josse retired in 1934 at the age of 68.
Inventions
Josse developed together with his construction engineer Wilhelm Gensecke (born January 19, 1880) a. a. an evaporative cooling machine (principle according to Josse-Gensecke). The inventors have been granted numerous other patents both at home and abroad, both individually and collectively.
