In 1914 Schrödinger achieved [[habilitation]] (''venia legendi''). Between 1914 and 1918 he participated in war work as a commissioned officer in the Austrian fortress artillery ([[Gorizia]], [[Duino]], [[Sistiana]], Prosecco, Vienna). In 1920 he became the assistant to [[Max Wien]], in [[Jena]], and in September 1920 he attained the position of ao. Prof. (''[[ausserordentlicher Professor]]''), roughly equivalent to Reader (UK) or associate professor (US), in [[Stuttgart]]. In 1921, he became o. Prof. (''[[ordentlicher Professor]]'', i.e. full professor), in [[Breslau University|Breslau]] (now Wrocław, Poland).<ref name="The Nobel Prize in Physics 1933"/>

In 1921, he moved to the [[University of Zurich|University of Zürich]]. In 1927, he succeeded [[Max Planck]] at the [[Humboldt University of Berlin|Friedrich Wilhelm University]] in Berlin. In 1933, Schrödinger decided to leave Germany because he strongly disapproved of the Nazis' antisemitism. He became a Fellow of [[Magdalen College]] at the [[University of Oxford]]. Soon after he arrived, he received the Nobel Prize in Physics together with [[Paul Dirac]]. His position at Oxford did not work out well; his unconventional domestic arrangements, sharing living quarters with two women,{{sfn|Moore|1992|pp=278 ff.}} were not met with acceptance. In 1934, Schrödinger lectured at [[Princeton University]]; he was offered a permanent position there, but did not accept it. Again, his wish to set up house with his wife and his mistress may have created a problem.<ref>[https://www.deutsche-biographie.de/sfz106819.html "Schrödinger, Erwin Rudolf Josef Alexander"] {{Webarchive|url=https://web.archive.org/web/20110427042804/https://www.deutsche-biographie.de/sfz106819.html |date=27 April 2011 }} in ''Deutsche Biographie''</ref> He had the prospect of a position at the [[University of Edinburgh]] but visa delays occurred, and in the end he took up a position at the [[University of Graz]] in Austria in 1936. He had also accepted the offer of chair position at Department of Physics, [[Allahabad University]] in India.<ref>{{cite web |url=https://www.jta.org/1940/05/20/archive/bombay-university-names-refugee-scientist-to-faculty |title=Bombay University Names Refugee Scientist to Faculty |publisher=Jewish Telegraphic Agency |date=20 May 1940 |access-date=14 August 2016 |archive-date=27 October 2016 |archive-url=https://web.archive.org/web/20161027074754/http://www.jta.org/1940/05/20/archive/bombay-university-names-refugee-scientist-to-faculty |url-status=live }}</ref>

In the midst of these tenure issues in 1935, after extensive correspondence with [[Albert Einstein]], he proposed what is now called the "[[Schrödinger's cat]]" [[thought experiment]].<ref>{{cite journal |last1=Bhaumik |first1=Mani L. |title=Is Schrödinger's Cat Alive? |journal=Quanta |date=2017 |volume=6 |issue=1 |page=75 |doi=10.12743/quanta.v6i1.68 |doi-access=free|arxiv=2211.17086 }}</ref>
