Life

Ettingshausen was the son of Major General Constantin von Ettingshausen (1760-1826); his younger brother Sigmund von Ettingshausen (1805–1855) also became major general. His son Constantin von Ettingshausen also became a scientist, as did his son Albert von Ettingshausen .

Ettingshausen studied philosophy and law in Vienna , also attended the bombing school, since he was destined for a military career, but turned to the subject after the general peace came. In 1817 he became an adjunct in mathematics and physics at the University of Vienna, in 1819 professor of physics in Innsbruck and in 1821 professor of higher mathematics in Vienna. The lectures he gave at that time mark a new era for the University of Vienna; they appeared in 2 volumes in 1827.

In 1834 Ettingshausen took over the chair of physics, from 1839–1842 he promoted the first attempts at photography in Vienna as a member of the "Fürstenhof Round" , in 1848 he transferred to the engineering academy and taught there for four years until it was converted into a purely military genius school. In 1852 he held a course in higher engineering at the polytechnic institute, and in the same year he took over the direction of the physical institute at the university, from which a large number of studies emerged under his direction.

Ettingshausen was one of the first to construct an electromagnetic machine that used electrical induction to generate electricity , also promoted optics and wrote a textbook on physics (Vienna 1844, 4th edition 1860), which had a major influence on the method of teaching physics Has.

He also wrote: Die combinatorial analysis (Vienna 1826); The principles of today's physics (Vienna 1857); he also worked with Andreas von Baumgartner on his theory of nature (7th edition, Vienna 1842) and with the same published the magazine for physics and mathematics from 1826–32 .

He had been a member of the Leopoldina since 1862 and a corresponding member of the Göttingen Academy of Sciences since 1864 . In 1866 Andreas von Ettingshausen retired and was raised to the baron status. He was a founding member and for several years also the first general secretary of the Vienna Academy of Sciences . He was a member of the Society of German Natural Scientists and Doctors .

In 1913 the Ettingshausengasse in Vienna- Döbling (19th district) was named after him.

The notations for binomial coefficients commonly used today go back to Ettinghaus.
