*This page celebrates mathematics at Cornell by highlighting some of the notable past faculty*

At the opening in 1868, the mathematics faculty was composed of one Professor (E.W. Evans) and one Assistant Professor (Z.H. Potter). Over 400 student enrolled at Cornell that year.

Forty years later, in 1908, the department consisted of 4 Professors, 3 Assistant Professors and 4 Instructors. About 4,800 students were enrolled at Cornell. Of these, about 350 were women and about 300 were graduate students.

In 1938, there was 5 Professors, 6 Assistant Professors and 8 Instructors. The student enrollment at Cornell was about 7,000 including 1,400 women and 1,000 graduate students. About 160 women were enrolled as graduate students.

In 1968, the department had grown to include 20 Professors, 7 Associate Professors, 19 Assistant Professors and 3 Instructors. The undergraduate enrollment had reached 10,000. The current undergraduate enrollment is around 14,000.

**From the opening of the university in 1868 to 1898**

### Evan William Evans

The first Chair of the department was educated at Yale and came from Marietta College, Ohio. He was among one of the first professors elected by the board of trustees. His interest in the language of his native country, Wales, led him to pursue studies the Cymric literature and philology, for which he is said to have had no superior in the United States. His teaching of analytic geometry is said to have influenced William Byerly.

### William Byerly

In 1873, Byerly received the first mathematics Ph.D. awarded at Harvard and joined the Cornell faculty. He was a student of Benjamin Peirce. At Cornell, he advocated the development of athletic facilities and his departure for Harvard in 1876 was lamented by students. He taught at Harvard for the rest of his career and had a lasting impact on the Harvard curriculum. He was a fellow of the American Academy of Arts and Sciences.

### James Edward Oliver

A graduate from Harvard and student of B. Peirce, Oliver had been recommended to A.D. White for the first appointment in mathematics. He was hired 3 years later, in 1871, and became Professor and Chair in 1873-74. He shaped the future of the department by reforming the undergraduate curriculum and promoting research and graduate education. He supervised 5 of the first 6 graduate students who earned a mathematics Ph.D. at Cornell. Three of those were women. He was a fellow of the American Academy of Arts and Sciences and a member of the National Academy of Sciences. He published one of the earliest articles by a Cornell faculty member: "A projective relation among infinitesimal elements", Ann. of Math. 1 (1884).

### James McMahon

James McMahon arrived in Ithaca in January 1883. He had been a brilliant student at Trinity College in Dublin and had received a much more sophisticated mathematics education than his Cornell colleagues (he received an MA from Dublin in 1890 and an honorary D.Sc in 1918). He and Oliver were the only faculty performing research during the early years. His first published work was "On a property of an imaginary line passing through one of the circular points at infinity", Ann. of Math. 4 (1888). Later, he wrote on Bessel functions and his last work, Hyperspherical Geometry and its Application to Correlation Theory for N Variables,15 Biometrika, 173–208 (1923), was published posthumously. He served as the American Association for the Advancement of Science’s Secretary (1897), Section A ( and Astronomy); General Secretary (1898), and Vice-President (1901). It is very likely that Arthur Rollin Harris, who received his Cornell Ph.D. in 1888 and became a world expert in tidal theory, was McMahon's student. Harris' work figured preeminently in McMahon's 1902 AAAS address entitled “Some Recent Applications of the Function Theory to Physical Problems”. After Oliver's death in 1895, McMahon played an important role in maintaining research activities in the department.

### Ernst Ritter

Ernst Ritter obtained his Ph.D. summa cum laude from Göttingen in 1891 under Felix Klein. He became Klein's assistant and one of his closest collaborators on the subject of function theory (automorphic functions). His work and ideas appear in the book "Vorlesungen über die Theorie der automorphen Functionen" written by R. Fricke and F. Klein (1897) whose 1903 review in the Bulletin of the American Mathematical Society was written by J.I. Hutchinson. In Hermann Weyl's book "Die Idee der Riemanschen Fläche", Ritter is cited for his seminal work on an extended form of the Riemann-Roch theorem. Ritter's acceptance of a position of Assistant Professor at Cornell was announced in a New York Times article published May 20, 1895. Sadly, Ritter never reached Ithaca. He fell ill during his crossing of the Atlantic and died at Ellis Island from a typhus attack on September 23, 1995 at the age of 28. Read more about Ernst Ritter.

### From 1898 to 1938

### John Irwin Hutchinson

In 1896, Hutchinson received the first Ph.D. awarded at Chicago (an honor he shares with L.E. Dickson) where he had followed his mentor, Oskar Bolza, after starting his graduate studies at the newly founded Clark University. He was a specialist of automorphic functions. His paper On the Roots of the Riemann Zeta Function, Transactions AMS, Vol. 27, 1925, was the object of his talk at the 1924 International Congress of Mathematicians in Toronto. In his work, he found all zeros of the Riemann Zeta function with |Im(z)| ≤ 300, the record at the time (see H.M. Edwards, "Riemann's Zeta Function", pg 126-132). Through her will, Mrs. Hutchinson established the Hutchinson Graduate Fellowship in in 1947. It is awarded annually by the Department of to graduate students who have demonstrated outstanding work as teaching assistants or as students in the graduate program.

### Virgil Snyder

Snyder studied algebraic geometry under F. Klein and obtained his Ph.D. at Göttingen in 1895 supported by a Cornell Erastus Brooks fellowship. He returned to Cornell and served the department for 43 years until his retirement in 1938. At Cornell, Snyder supervised over 40 graduate students including a large number of women. He spoke at The International Congress of Mathematicians in 1928, '32 and '36. Three of his students also spoke at the International Congress of Mathematicians between 1924 and 1936. He served as President of the AMS (1928) and was a fellow of the American Academy of Arts and Sciences.

### George Abraham Miller

After travelling in Europe and attending the lectures of Sophus Lie in Leipzig and Camille Jordan in Paris, Miller taught at Cornell between 1897 and 1901. He then moved to Stanford and, later to the University of Illinois. In 1900, he received a prize from the Cracow Academy for the determination of all 994 intransitive groups of degree ten. After Professor Oliver’s death in 1895, Miller was the next to advise Ph.D. students and his four Cornell students had very successful academic careers. Miller spoke at the 1924 International Congress of Mathematicians in Toronto. He served as President of the Mathematical Association of America, was a fellow of the American Academy of Arts and Sciences and a member of the National Academy of Sciences.
