Emanuel Rosenberg (born November 28, 1872 in Vienna , † March 30, 1962 in Bogotá ) was an Austrian electrical engineer and inventor .

Life

After graduating from high school, the Jewish merchant's son Emanuel Rosenberg devoted himself to studying electrical engineering at the Vienna University of Technology , which he completed in 1895 with the academic degree of Dr. techn. completed. Rosenberg began his professional career as an engineer at the company Kremenezky, Mayer & Co., which later became the Austrian Schuckert Works in Vienna. In 1900 Rosenberg moved to Hanover as chief engineer , and from 1907 to 1914 he worked for Westinghouse in Manchester .

In 1916 Rosenberg returned to Austria after working in the Netherlands , where he was head of Elin AG for electrical industry in Vienna-Weiz from 1917 to 1938 . After the invasion of the National Socialists , Rosenberg fled to Great Britain and moved to Colombia in 1940 , where he died in 1962 at the age of 89.

Rosenberg - a pioneer of electrical engineering - developed the cross -field machine named after him "Rosenberg machine" in 1904 , a direct current generator which was used in particular in electric welding (including the construction of the first fully welded European railway bridge in 1928) and also after named him "Rosenberg Dynamo" for electric train lighting and cinema lamps.

In 1954, Emanuel Rosenberg was awarded an honorary doctorate from the Technical University of Vienna in recognition of his services in the field of electrical engineering .
