The Center for Advanced Studies (CAS) was founded at Wesleyan University in 1959 and existed until 1969. The CAS invited fellows to reside at Wesleyan and participate in the intellectual life of the campus. Each year, the fellows were a diverse group of academics, scientists, social scientists, writers, artists, and other intellectuals. Sigmund Neumann served as director of CAS from 1959-1962, Paul Horgan from 1962 until 1967, and Phillip Hallie as acting director from 1967-1969. Victor Butterfield, president of Wesleyan University until 1967, was actively involved in the Center.
