## Cornell Mathematics Doctorates, 1940-1959.

The first Cornell campus elm trees where a gift of the Class of 1872 (they offered 72 elm trees). The John Ostrander's elm trees (pictured here in 1953, between Stimson and Goldwin Smith Halls) where planted in 1877. Ostrander was a local farmer and he was not rich. He offered the best elm trees from his farm.

Before 1940, one hundred and one Ph.D.s were awarded in mathematics at Cornell including twenty two to women. The first, in 1872, went to Henry Turner Eddy who was Assistant Professor in Mathematics at the time.

The Cornell mathematics graduate program owes its early success to the leadership of James Oliver, Chair from 1874 to his death in 1895. The most prolific graduate advisor before 1940 was the algebraic geometer Virgil Snyder who supervised 43 Cornell Ph.D.s.

This page gives the complete chronological list of the people who earned a doctorate in mathematics at Cornell between 1940 and 1959 included. The list is organized by periods of 5 years. Sixty Ph.D.s were awarded during this period at a very steady average of about 3 per year (only 5 went to women).

This is a very successful time for the Cornell Mathematics Graduate Program which corresponds to the renaissance of the department during and after WWII. Mary Dolciani, Irving Reiner, Murray Rosenblatt, Joanne Elliott, Steven Orey, Daniel Ray, Jean-Pierre Meyer, Louis De Branges and Harry Kesten graduated during this period and the most active advisors were Mark Kac (16), John Barkley Rosser (8), Ralph Agnew, Burton W. Jones and Harry Pollard (6) and William Feller (5).

## Cornell Mathematics Doctorates, 1960-1969

The sixties are a period of extraordinary growth at Cornell and in US higher education in general. It is also the period of the Vietnam War protests on Campuses and of the racial tensions that led to the occupation of Willard Straight in 1969.

Before 1960, 161 Ph.D.s were awarded in mathematics at Cornell. Between 1940 and 1959, the average number of doctorates was a very steady 3 per year.

Seventy three Mathematics Ph.D.s were awarded at Cornell in the sixties, twenty one during the first half of the decade and fifty two during the second half. Eight Ph.D.s were earned by women. The year 1965 is the first in which more than 10 doctorates wee awarded. Twenty two faculty supervised at least one Ph.D. during this period. The most active were Anil Nerode (11), Peter Hilton and Alex F.T.W. Rosenberg (6), Jack Kiefer (5) Israel Berstein, Wolfgang Fuchs and Gerald Sacks (4). Remarkably, Sacks is also one of the students who received their Ph.D. during this period.

## Cornell Mathematics Doctorates, 1970-1979

From Cornell: A History 1940-2015 by Glenn C. Altschuler and Isaac Kramnick: *In 1974, Corson and the Board of Trustees announced the first balanced endowed budget in eight years. But good time were fleeting, as rampant inflation and a dramatic decline in the stock market hit Cornell in 1974 and 1975. Cornell's endowment dropped from $318 million to $271 million. The State of New York cut back $3.3 million in payments to Cornell in 1974, resulting in the loss of ninety jobs. Corson returned to gloom and doom. "Since 1965 I have not seen a situation so uncertain and so potentially serious as the one we face right now" he noted, even though he understood that "the whole Campus is tired of hearing about troubles".*

The Johnson Museum of Arts was built in 1973 near White Hall.

The Mathematics Department was hit hard during the budget cuts of seventies but the graduate program produced one hundred seventeen Ph.D.s during that decade, a record. Only eleven of the recipients were women. Thirty nine different faculty supervised these doctorates. The most active faculty during this decade were Anil Nerode (13), Leonard Gross (12), Alex F.T.W. Rosenberg (8), Frank Spitzer (7), and Clifford Earle and Harry Kesten (6).

## Cornell Mathematics Doctorates, 1980-1989

Following the record 117 mathematics doctorates awarded at Cornell during the previous decade, only sixty one were awarded from 1980 to 1989. Thirteen went to women.

Thirty three faculty supervised at least one Ph.D.s during this decade. Anil Nerode (6) and John Hubbard (5) were the most active, followed by Louis Billera, Kenneth Brown, Marshall Cohen, Leonard Gross, Stephen Lichtenbaum, Lawrence Payne, Alex F.T.W. Rosenberg and Richard Shore (3).

In 1986, the Mathematical Science Institute was created under the leadership of Geoffrey Ludford, Professor of Theoretical and Applied Mathematics, and with the help of Charlie Van Loan (Computer Science), Lars Wahlbin (Mathematics), and Narahari Prabhu (OR-IE). It was supported for ten years by a grant from Army Research Office.

## Cornell Mathematics Doctorates, 1990-1999

The Mathematical Science Institute (1986-1997) was supported for ten years by a grant from the Army Research Office. The four designated areas of research in the Institute were applied analysis, physical mathematics, numerical analysis and statistics and applied probability. For most of the institute existence (1987-1997), Anil Nerode served as Director.

On October eight 1998, to everyone surprise, a large Pumpkin was discovered at the top of McGraw tower. It remained there until the next spring.

Ninety three doctorates were awarded during this decade including sixteen to women. After the swings of the previous two decades, the annual rate of 9 to 10 per year became the norm. Thirty nine faculty supervised Ph.D.s during the period. The most active advisors were Richard Durrett (12 students) followed by Leonard Gross (9), Anil Nerode (6), Allen Hatcher (5), and Kenneth Brown, John Hubbard, Richard Shore, Roberts Strichartz and Karen Vogtmann (4).

## Cornell Mathematics Doctorates, 2000-2009

In 1999, after having occupied White Hall for most of its existence, the department move to Malott Hall, the former home of the Johnson School named after Deane Waldo Malott, the sixth president of Cornell University (1951-1963). Malott Hall's north wing was build in 1963 (Architects: Warner, Burns, Toan & Lunde). The south wing (annex) was added in 1977 (Architects: Levatich, Miller & Hoffman). The architectural drawing pictured here (1975) is from John Clair Miller and Alex Krueger, for the addition project. John Clair Miller is Professor Emeritus in the College of Architecture, Arts and Planning.

Ninety nine doctorates were awarded during the first decade of the twenty-first century. From 2000 to 2006, the graduate program was supported in part by a Vertical Integration of Research and Education in the Mathematical Sciences (VIGRE) grant from the Division of Mathematical Sciences at the National Science Foundation. The goal of this program was "to increase the number of well-prepared U.S. citizens, nationals, and permanent residents who pursue careers in the mathematical sciences". The NSF phased-out the VIGRE program by the end of the decade. Thirty five faculty supervised graduate students during this decade. The most active were Anil Nerode and Laurent Saloff-Coste (7), Louis Billera, Kenneth Brown and Mike Stillman (6), Leonard Gross, John Hubbard and Lars Wahclbin (5), and Jose Escobar, Richard Shore and Karen Vogtmann (4).

## Cornell Mathematics Professors and their graduate students before 1940

The Mathematics graduate program at Cornell owes much to the vision and leadership of James Edward Oliver. His teacher, Benjamin Peirce, always said that "Jimmy Oliver was the best mathematician who had ever come under his notice."

This page provides, for each mathematics faculty who did advised graduate students, the complete list of the Cornell mathematics Ph.D.s they supervised. Only those faculty all of whose Cornell students obtained their Ph.D. before 1940 are included here. Except for James Oliver who come first, the faculty are listed in decreasing order of the number of Ph.D.s earned under their supervision. Two faculty, Ralph Agnew and Burton Wadsworth Jones, advised graduate students at Cornell both before and after 1940 and are not listed here. The years given for each faculty are the years of appointment at Cornell (not including emeritus appointment).
