There are more than 250 decorative stained glass windows in the Hall of Graduate Studies crafted by G. Owen Bonawit and his New York firm. Many windows represent various disciplines in the Graduate School curriculum. The McDougal Common Room windows feature the Natural Sciences and Engineering, while the HGS Dining hall depicts the Arts and Humanities. Some are versions of historic woodcut prints housed at Yale, while others are more fanciful modern designs by the artists. They blend the ancient and the modern as a model for graduate education.
