From the opening of Cornell in 1868 to 1898
The first American mathematics Ph.D. was awarded at Yale in 1862. Ten years later, Cornell granted its first mathematics Ph.D. (and first Ph.D. in any discipline).
Henry Turner Eddy, 1872
In 1872, Eddy received the first Ph.D. awarded by Cornell in any subject. He had been an Assistant Professor in at Cornell since 1869. He left Cornell in 1873 for an exemplary academic career that took him to the University of Cincinnati, Rose Polytechnic Institute (he served as president at both institutions) and the University of Minnesota where he retired in 1912. He was one of the invited speakers at the 1893 Chicago Congress of Mathematicians at the World's Columbian Exposition where he spoke on "Modern Graphical Methods".
Hiram John Messenger, 1886
Messenger wrote a dissertation titled "Modern Methods in Geometric Conics" under J. Oliver. He received the second Ph.D. awarded at Cornell, 14 years after Eddy, and was Oliver's first graduate student. After serving as Adjunct Professor at NYU (then, University of the City of New York) for several years, he became an actuary and a Cornell Trustee. The Messenger Lectures are named after him.
Rollin Arthur Harris, 1888
Harris' dissertation was on "The Theory of Images in the Representation of Functions". It was, most probably, supervised by James McMahon. After graduating, he was a fellow at the newly created Clark University. Harris had an illustrious career in the Tidal Division of the US Coast and Geodesic Survey, and at the time of his death (1918) he was considered one of the world experts in tidal theory. His work was theoretical, experimental and computational. He was one of the two designers of “Old Brass Brains”, the Tide Predicting Machine No. 2 that was in constant used from 1910 to 1960 by the National Oceanographic and Atmospheric Administration (NOAA). Harris published mathematical articles and his work on tidal theory was featured in J. McMahon's 1902 address to the Association for the Advancement of Science as a significant example of application of mathematics.
Ida Metcalf, 1893
Metclaf received a Ph.B. at Boston University in 1886 with a thesis titled "The Origin and Development of Styles in Architecture". She is only the second American women to obtain a Ph.D. in mathematics (and the first at Cornell). Her dissertation was titled "Geometric Duality in Space" and was supervised by James Oliver. She taught mathematics before and after her Ph.D., including at the newly opened Bryn Mawr School in 1891 after earning a Master at Cornell in 1889. She worked as a teacher and also as a security analyst until 1910 when she entered the civil service in New York City. She worked in the office of the Controller of New York City as a statistician until her retirement in 1921.
Agnes Sime Baxter, 1895
Baxter’s dissertation, "On Abelian integrals, a resume of Neumann’s ‘Abelsche Integrele’ with comments and applications", was the sixth and last supervised by J. Oliver. Following Oliver’s death in 1895, she edited his mathematical notes. Baxter is the second Canadian Women to receive a mathematics Ph.D. and the third women to receive a Ph.D. at Cornell under James Oliver.
From 1898 to 1918
Oliver's death in 1895 was a blow to the Cornell graduate program and led to a six year gap during which no Ph.D.s were awarded. George A. Miller and V. Snyder were the first to advise graduate students after Oliver's death.
William Benjamin Fite, 1901
Fite was an undergraduate at Cornell and stayed as a graduate student. His dissertation, "On Metabelian Groups", was supervised by George Miller. He is the first Cornell Ph.D. of the post Oliver period. He published research papers throughout is successful career. He stayed at Cornell as Assistant Professor before moving to Columbia in 1911. He became Professor and stayed at Columbia until his retirement in 1942 as the Davies Professor of Emeritus. He succeeded Cornell faculty member John Henry Tanner as Treasurer for the American Mathematical Society and served in this role from 1921 to 1929.
Henry Lewis (Louis) Rietz, 1902
Rietz is another one of G. Miller’s graduate students and his dissertation was titled "On primitive groups of odd orders". After several years at the University of Illinois, where he developed an interest for Actuarial Science and Mathematical Statistics, Rietz joined the University of Iowa, where he remained for the rest of his career. There he played an important role in the development of Mathematical Statistics, training several generations of American statisticians. Thanks in part to his student Samuel Wilks, later Professor at Princeton, Rietz is credited by the Genealogy Project with over a thousand academic descendants, a record among Cornell Ph.D.s. He served as president of the Mathematical Association of America and of the Institute for Mathematical Statistics.
Clarence Lemuel Elisha Moore, 1904
Moore’s dissertation was on the "Classification of the Surfaces of Singularities of the Quadratic Spherical Complex". He is the second of the forty-three graduate students advised by V. Snyder at Cornell. Moore became Professor at the Massachusetts Institute of Technology. He was a fellow of the American Academy of Arts and Sciences. His name is attached to one of the most prestigious junior positions that a promising mathematician can hold, the C.L.E. Moore instructorships offered by the Department of at MIT. The position was created in 1948 and the former recipients include Nobel Prize winner John Nash and Fields medalists Daniel Quillen, Paul Cohen and Curt McMullen.
John Wesley Young, 1904
Young's dissertation is titled "On the group of the sign (0, 3, 2, 4, ∞) and the functions belonging to it". His advisor was John I. Hutchinson although he had worked earlier under George Miller (Miller left Cornell in 1901). Young collaborated with O. Veblen on the book "Projective Geometry". He spent most of his career at Dartmouth where he served as Head and, later, Chair. Dartmouth's postdoctoral Instructorships in mathematics are named after him. He served as president of the Mathematical Association of America.
Charles Herschel Sisam, 1906
Sisam's dissertation was on the "Classification of Scrolls of Order Seven Having a Rectilinear Directrix" and was supervised by V. Snyder. Sisam went to postdoctoral studies at Göttingen and Turin and spend most of his career as Chair of at Colorado College. He was an invited speaker at the 1924 and 1928 International Congress of Mathematicians in Toronto and Bologna, becoming - with H. Rietz - the first Cornell Ph.D. to be invited to speak at an ICM.
Francis Robert Sharpe, 1907
Sharpe studied at Cambridge (Christ’s College) before moving to Canada and the United States. At Cambridge, he was Second Wrangler in 1892. He wrote his dissertation under John McMahon on "The General Circulation of The Atmosphere". He stayed at Cornell for his entire career, becoming a close collaborator of V. Snyder. He served as Chair of the department from 1923 to 1926. He is the first of two Cornell Ph.D.s who served as Chair of the department.
Anna Lavinia Van Benschoten, 1908
Van Benschoten received both her B.S. and Ph.D. at Cornell, writing a dissertation on "The Birational Transformation of Algebraic Curves of Genus Four" under V. Snyder. She also studied at Chicago (M.S.) and Göttingen, before working as Professor of at Wells College from 1901 to 1920. She was a charter member of the Mathematical Association of America. She is the first women graduate of the post-Oliver period and the first of the thirteen women who received a Ph.D. under V. Snyder at Cornell.
