The Weizmann Institute of Science (מכון ויצמן למדע) is an institute of higher learning and research in Rehovot, Israel. It differs from other Israeli universities in that only a graduate program is offered, and only in natural sciences.
Originally founded in 1934 by Chaim Weizmann as the Daniel Sieff Research Institute, it was expanded and formally rededicated as the Weizmann Institute of Science (מכון ויצמן למדע) on November 2, 1949. Following further expansion and the accreditation of a graduate school, it is now best described as a research university. It presently has about 2,500 students, staff, and faculty, and offers M.Sc. and Ph.D. degrees in Mathematics, Computer Science, Physics, Chemistry, and Biology, as well as several interdisciplinary programs.
Weizmann's scientific assistance to the Allied forces in World War I brought him into close contact with British leaders, enabling him to play a key role in the issuing of the Balfour Declaration on November 2, 1917 in which Britain committed itself to the establishment of a Jewish home in Palestine.
That same year Weizmann met in Aqaba with Emir Feisal, son of Sherif Hussein of Mecca, the leader of the Arab movement, to discuss prospects of reaching an understanding on the establishment of independent Arab and Jewish states.
Chaim Azriel Weizmann (חיים ויצמן) (also: Chaijim W., Haim W.) (November 27, 1874 – November 9, 1952) chemist, statesman, President of the World Zionist Organization, first President of Israel (elected May 16, 1948, served 1949 - 1952) and founder of a research institute in Israel which eventually became the WeizmannInstitute of Science.
Weizmann was born in a small village Motol (Motyli) near Pinsk (Russian Empire, now in Belarus) and graduated in chemistry from the University of Fribourg in Switzerland in 1899.
In 1921 Weizmann went along with the known Jewish physicist Albert Einstein for a fund-raiser to establish a Hebrew University in Jerusalem.
