From 1914, Einstein has served as a professor at the Humboldt University of Berlin, although with a special clause freeing him from most teaching obligations.

From 1914 to 1932 he has also directed the Kaiser Wilhelm Institute for Physics.

Einstein is a socialist Zionist who supports the creation of a Jewish national homeland in the British mandate of Palestine.

In 1931, The Macmillan Company publishes About Zionism: Speeches and Lectures by Professor Albert Einstein.

Querido, an Amsterdam publishing house, had collected eleven of Einstein's essays into a 1933 book entitled Mein Weltbild, translated to English as The World as I See It; Einstein's foreword dedicates the collection "to the Jews of Germany".

One of the first actions of Hitler's administration is the Law for the Restoration of the Professional Civil Service, which removes Jews and politically suspect government employees (including university professors) from their jobs, unless they have demonstrated their loyalty to Germany by serving in the Great War.

In response to this growing threat Einstein had prudently traveled to the U.S. in December 1932.

For several years he had been wintering at the California Institute of Technology in Pasadena, California, and has also been a guest lecturer at Abraham Flexner's newly founded Institute for Advanced Study in Princeton, New Jersey, where, in 1933, the Einsteins purchase a house; he is to remain an integral contributor to the Institute for Advanced Study until his death in 1955.

Einstein has begun to write affidavits recommending United States visas for a huge number of European Jews who are trying to flee growing persecution.

He raises money for Zionist organizations and is, in part, responsible for the formation, in 1933, of the International Rescue Committee.
