The Hebrew University of Jerusalem (HUJI; הַאוּנִיבֶרְסִיטָה הַעִבְרִית בִּירוּשָׁלַיִם) is a public research university based in Jerusalem, Israel. Co-founded by Albert Einstein and Chaim Weizmann in July 1918, the public university officially opened in April 1925. It is the second-oldest Israeli university, having been founded 30 years before the establishment of the State of Israel but six years after the older Technion university. The HUJI has three campuses in Jerusalem and one in Rehovot. The world's largest library for Jewish studies—the National Library of Israel—is located on its Edmond J. Safra campus in the Givat Ram neighbourhood of Jerusalem.
The university has five affiliated teaching hospitals (including the Hadassah Medical Center), seven faculties, more than 100 research centers, and 315 academic departments. , one-third of all the doctoral candidates in Israel were studying at the HUJI.
Among its first few board of governors were Albert Einstein, Sigmund Freud, Martin Buber, and Chaim Weizmann. Four of Israel's prime ministers are alumni of the university. , 15 Nobel Prize winners (8 alumni and teachers), two Fields Medalists (one alumnus), and three Turing Award winners have been affiliated with the HUJI.
One of the visions of the Zionist movement was the establishment of a Jewish university in the Land of Israel. Founding a university was proposed as far back as 1884 in the Kattowitz (Katowice) conference of the Hovevei Zion society, and by Hermann Schapira at the First Zionist Congress of 1897.
The cornerstone for the university was laid on 24 July 1918. Seven years later, on 1 April 1925, the Hebrew University campus on Mount Scopus was opened at a gala ceremony attended by the leaders of the Jewish world, distinguished scholars and public figures, and British dignitaries, including the Earl of Balfour, Viscount Allenby, Winston Churchill and Sir Herbert Samuel. The university's first chancellor was Judah Magnes, who led the school as chancellor from 1924 to 1935. In 1935 to 1948 he led the school as president.
