Near East (628–639 CE): Plague and Aftermath…

Woodrow Wilson, who has become a popular lecturer at Princeton, had published his third book, entitled Division and Reunion, in 1893.

It will become a standard university textbook for teaching mid- and late- nineteenth century U.S. history.

In 1897, Houghton Mifflin publishes Wilson's biography on George Washington.

In February 1890, with the help of friends, Wilson had been elected by the Princeton University Board of Trustees to the Chair of Jurisprudence and Political Economy, at an annual salary of three thousand dollars (equivalent to $83,656 in 2018).

He quickly gained a reputation as a compelling speaker.

During his time as a professor at Princeton, he also delivered a series of lectures at Johns Hopkins, New York Law School, and Colorado College.

In 1896, Francis Landey Patton announced that Princeton would henceforth officially be known as Princeton University instead of the College of New Jersey, and he unveiled an ambitious program of expansion that included the establishment of a graduate school.

In the 1896 presidential election, Wilson rejected Democratic nominee William Jennings Bryan and supported the conservative "Gold Democrat" nominee, John M. Palmer.

Wilson's academic reputation continues to grow throughout the 1890s, and he turns down positions at Johns Hopkins, the University of Virginia, and other schools because he wants to remain at Princeton.

Woodrow Wilson, now the author of a several articles and (ultimately) nine books, publishes his five-volume History of the American People in 1902, the year in which Princeton’s trustees unanimously choose him, in June, as president of the university.

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.

In 1972, Douglas D. Osheroff, David M. Lee, and Robert C. Richardson of the United States first observe superfluidity in helium-3.
