In which universities did Einstein serve as a professor till the 1930s?

Despite publishing four ground-breaking scientific papers in 1905 and earning his doctorate, Einstein still had difficulty finding a teaching job. He finally became a lecturer at the University of Berne in 1908. He received more opportunities in academia as his reputation as a theoretical physicist grew.

A year after joining the University of Berne he became an associate professor of physics at the University of Zurich. In 1911, he became a full professor at the University of Prague but returned after a year as a full professor to Zurich. The highlight of his academic career was when he became a professor at the University of Berlin and a member of the Prussian Academy of Sciences.

He had also been the Director of the Kaiser Wilhelm Institute for Physics. Einstein earned the salary of a professor without any teaching duties at the University of Berlin. As a result, he could pursue his research full time. He remained in the University of Berlin until the early 1930s.
