The Institute for Advanced Study, established in 1930, began with twenty-three Members in the School of Mathematics with Albert Einstein as one of its first Professors. Since then, the Institute’s community of scholars has grown to include more than seven thousand historians, mathematicians, natural scientists, and social scientists. A Faculty of some thirty permanent Professors selects and mentors the roughly two hundred Members who arrive each year from around the world, about 60 percent from outside the United States, typically from more than thirty different countries.f
