The Weizmann Institute of Science (Hebrew: מכון ויצמן למדע‎ Machon Weizmann LeMada), known as Machon Weizmann is a university and research institute in Rehovot, Israel. It differs from other Israeli universities in that it offers only graduate and post-graduate studies in the sciences. It is one of the world’s leading multidisciplinary research centers, with around 2,500 scientists, postdoctoral fellows, Ph.D. and M.Sc. students, and scientific, technical, and administrative staff working at the Institute. In 2011, the magazine The Scientist rated the Weizmann Institute as the best place in the world to work in academia among non-US institutions. Founded in 1934 by Chaim Weizmann and Benjamin M. Bloch as the Daniel Sieff Research Institute, it was renamed the Weizmann Institute of Science in his honor on November 2, 1949. Before he became President of the State of Israel, Weizmann pursued his research in organic chemistry at its laboratories. The Weizmann Institute presently has about 2,500 students, staff, and faculty, and awards M.Sc. and Ph.D.
