Established by an act of the
Yale Corporation in August 1847, the Graduate School of Arts and Sciences was originally called the "Department of Philosophy and the Arts" and enrolled eleven students who had completed four-year undergraduate degrees. The Department was also the precursor of the
Sheffield Scientific School, which was cleaved from the department in 1854. The program offered seminars in chemistry and metallurgy, agricultural science, Greek and Latin literature, mathematics, philology, and Arabic. The faculty consisted of two full-time science professors, chemists
Benjamin Silliman, Jr. and
John P. Norton, and five
Yale College faculty members who offered advanced courses in their subject areas. Following the model of German research universities, the Scientific School faculty established a
Doctor of Philosophy degree in 1860.
NYU's School of Practical and Analytical Chemistry, the
University of Pennsylvania,
Harvard University, and
Princeton University established similar programs over the next two decades. In 1892, seven years after Yale organized as a university, the Graduate School of Arts and Sciences was officially formed, and
Arthur Twining Hadley was appointed dean. Hadley became Yale's
13th president in 1899. In 1920, the Graduate School was assigned its own governing board, and under Dean
Wilbur Lucius Cross (1916-1930), it attracted a large and distinguished scholarly faculty. Beginning in the late nineteenth century, race and gender restrictions on graduate admissions were gradually relaxed. In 1876
Edward Alexander Bouchet (Yale B.A. 1874) received a doctorate in Physics, becoming the first African American to earn a Ph.D. in the United States and the sixth recipient of a doctorate in the field. Women were admitted into the Graduate School in 1892. In 1894, seven women received Ph.D.s from Yale, including
Mary Augusta Scott (English), Laura Johnson Wylie (English), Elizabeth Deering Hanscom (English),
Margaretta Palmer (Mathematics),
Charlotte Fitch Roberts (Chemistry), and sisters Cornelia H. B. Rogers (Romance Languages and Literatures) and Sara Bulkley Rogers (History). ==Organization==
