Institute for Advanced Study, a center for scholars at Princeton, New Jersey. It conducts no regular courses and awards no degrees. Its members, selected from throughout the world, attend the institute usually for one or two years. In informal association with its faculty, they engage in original research in one of the institute's four schools—mathematics, natural sciences, social sciences, and historical studies. Faculty members do no formal classroom teaching and are free to work on their own research. Distinguished professors have included Albert Einstein, Niels Bohr, and J. Robert Oppenheimer. The institute, founded with funds provided by Louis Bamberger and his sister, Mrs. Felix Fuld, was opened in 1933. Abraham Flexner was its first director.
