It is motivated by questions such as: when did mathematical theories become applicable to a wide range of fields from medicine to the social science? How did this change occur? I ask after the implications of this transformation for the development of mathematics as an academic discipline and how it affected what it meant to be a mathematician. How did mathematicians understand the relation between abstractions and generalizations on the one hand and their manifestation in concrete problems on the other? Mathematics in Cold War America was caught between the sciences and the humanities. This dissertation tracks the ways this tension between the two shaped the development of professional identities, pedagogical regimes, and the epistemological commitments of the American mathematical community in the postwar period. Focusing on the constructed division between pure and applied mathematics, it therefore investigates the relationship of scientific ideas to academic and governmental institutions, showing how the two are mutually inclusive. Examining the disciplinary formation of postwar mathematics, I show how ideas about what mathematics is and what it should be crystallized in institutional contexts, and how in turn these institutions reshaped those ideas. Tuning in to the ways different groups of mathematicians strove to make sense of the transformations in their fields and the way they struggled to implement their ideological convictions into specific research agendas and training programs sheds light on the co-construction of mathematics, the discipline, and mathematics as a body of knowledge. The relation between pure and applied mathematics and between mathematics and the rest of the sciences were disciplinary concerns as much as they were philosophical musings. As the reconfiguration of the mathematical field during the second half of the twentieth century shows, the dynamic relation between the natural and the human sciences reveals as much about institutions, practices, and nations as it does about epistemological commitments.

This is undoubtedly true when it comes to the incredible support I have received from mentors, colleagues, friends, and family over the past six years. Academic writing, I can now attest with absolute certainty, is not a solitary pursuit. My committee has challenged me to think more critically, creatively, and broadly. This project would not have been possible without my committee's abundant help. First and foremost, I am deeply grateful to my academic advisor, David Kaiser, who made me feel like a colleague and a friend from day one. Dave's diamond-sharp intellect, his bottomless generosity and kindness, and his perpetual good humor have guided me along the way. Writing this dissertation has been a far more rewarding and enjoyable enterprise for having him as my advisor. He is thoughtful in every sense of the term and he has taught me to be a scholar. Joan Richards has shared her vast knowledge of and passion for the history of mathematics with me. She has pushed me to write more clearly and offered much needed moral support. Despite the rickety commuter rail, I cherish my trips to Providence to no end. Christopher Capozzola made me question whether I chose the right specialization - delving with him into the world of American history as he inculcated me into the historian's craft has been a true pleasure. The HASTS graduate program at MIT has been a wonderful environment in which to develop my ideas and I take great pride in counting myself among its members. I greatly benefited from the support, sage advice, and intellectual acumen of a host of faculty. Michael Fischer, Stefan Helmreich, Vincent Lepinay, Heather Paxson, Harriet Ritvo, and Susan Silbey have made my time at MIT both rich and rewarding. I thank them for that. In numerous workshops, practice talks, seminars, and less formal gatherings the graduate student community of HASTS taught me the true meaning of interdisciplinarity and collegiality. That we were always able to come together across our diverse interests is a testimony to the program's success. I extend special thanks to Marie Burks, Tom Schilling, David Singerman, and Benjamin Wilson. The rotating crew of 098 - Michael Rossi, Lisa Messeri, Rebecca Woods, and Emily Wanderer - were not only my invaluable interlocutors but also great friends. I wrote much of this dissertation while in residence at the Max Planck Institute for the History of Science in Berlin, Germany. My gratitude goes to Lorraine Daston for inviting me to take part in the vibrant intellectual community that is Department II. The history of science has never appeared as lively and alluring as it did during my year in Berlin. Etienne Benson organized the predoctoral seminar at the MPIWG where I had the pleasure to present my work. I am indebted to many visitors and permanent members of the department for helpful comments, stimulating conversations, and academic mentorship: Joao Rangel de Almeida, Elena Aronova, Dan Bouk, Jeremiah James, Elaine Leong, Christine von Oertzen, Dominique Pestre, David Sepkoski, Elena Serrano, Skiili Sigurdsson, Dora Vargha, and Annette Vogt. I especially thank Yulia Frumer, Courtney Fullilove, Megan McNamee, Kathleen Vongsathorn, and Oriana Walker for their infallible encouragement through the final stages of writing this dissertation. Somehow they made sure I never felt alone. 9 Stephanie Dick, Moon Duchin, and Christopher Phillips shared with me their interest in mathematics, its history and historiography. I attended and presented my work in the annual Physics Phunday on several occasions. I thank Michael Gordin, Peter Galison, and participating graduate students for generously reading my work, offering feedback, and sharing their research with me. I presented a chapter of this dissertation before members of Cornell University's STS Department. Stephen Hilgartner, Ronald Kline, Michael Lynch,

At this point, with almost no mathematical training and never having done any bio­ graphical writing, I became determined to write the life of David Hilbert, whom many considered the profoundest mathematician of the early part of the 20th century. Now, thirty years later, rereading Hilbert, certain questions come to my mind.

  • Constance Reid
    Constance Reid John Ewing, former director of the American Mathematical Society, says this of Constance Reid: “ She has a special talent for understanding mathematicians and their culture. She understands us. She is the Boswell for mathematics – a biographer who has made the mathematical life understandable to the general public and to mathematicians themselves. Her work has enriched our profession.” The “autobiography” of her sister Julia Robinson has been a source of inspiration for many young women contemplating careers in mathematics, and her biography of David Hilbert stands as one of the best mathematical biographies ever written. It is no exaggeration to say that publication of Hilbert made her a star among mathematical biographers. Her five lively and penetrating biographies of mathematicians have been highly praised and constitute a great contribution to the world of mathematics. She has set a high standard for future biographers. We are proud that she was a member of our section. Although the formal mathematical education of Constance Reid concluded with high school algebra and geometry, she was able to understand mathematical ideas well enough to write three best - selling popularizations of mathematics: From Zero to Infinity (1955), Introduction to Higher Mathematics (1959), and A Long Way From Euclid (1963). Several mathematicians have commented on the influence of From Zero to Infinity on their development. Her writing ability was early demonstrated in her book Slacks and Calluses(1944), an account of her working for a summer on a bomber factory assembly line in World War II. At the time she was a high school English teacher in San Diego and only twenty - six.

This recording was made in March 1977 by Evar Nering at his apartment in Scottsdale, Arizona. Tucker: I have recently received the tapes that Speed made and find that these tapes carried my history up to approximately 1938. So the plan is to continue the history. In the late '30s I was working in combinatorial topology with not a great deal of results to show. I guess I was really more interested in my teaching. I had an opportunity to teach an undergraduate course in topology, combinatorial topology that is, classification of 2-dimensional surfaces and that sort of thing.

Memorial Tributes: Volume 19 BERNARD BUDIANSKY 1925–1999 Elected in 1976 “Contributions to the understanding of buckling phenomena, materials behavior, and new mathematical analyses of structural response.” BY JOHN HUTCHINSON BERNARD BUDIANSKY, an engineering scientist whose re- search and teaching shaped the fields of structures and the me- chanics of materials, died at the age of 73 on January 23, 1999, in Lexington, Massachusetts. No one who interacted with Bernie would fail to remember the delightfully opinionated, thought- fully probing, 6′4″ man with a large personality to match. Bernie’s career coincided with the US space effort and the expansion of engineering research in American universi- ties. His first technical job after college was at the National Advisory Committee for Aeronautics (NACA). From 1955 until his retirement in 1995, he was on the faculty in the Division of Engineering and Applied Sciences at Harvard University, as the Gordon McKay Professor of Structural Mechanics from 1961 and then as the Abbott and James Lawrence Professor of Engineering from 1983. His early research and consulting were heavily influ- enced by his exposure to developments in space structures at NACA (predecessor of the National Aeronautics and Space Administration, NASA). Many of his early contributions focused on plate and shell structures in studies of buckling, vibrations, and flutter. His research interests were as dynamic as his persona. Over his career, he made fundamental contri- butions to plasticity theory, composite materials, and many 39 Copyright National Academy of Sciences. All rights reserved.

FLEMING URING HIS LONG CAREER Edward James McShane made D significant contributions to the calculus of variations, integration theory, stochastic calculus, and exterior ballistics. In addition, he served as a national leader in mathematical and science policy matters and in efforts to improve the undergraduate mathematical curriculum. McShane was born in New Orleans on May 10, 1904, and grew up there. His father, Augustus, was a medical doctor and his mother, Harriet, a former schoolteacher. He gradu- ated from Tulane University in 1925, receiving simultaneously bachelor of engineering and bachelor of science degrees, as well as election to Phi Beta Kappa. He turned down an offer from General Electric and instead continued as a student instructor of mathematics at Tulane, receiving a master’s degree in 1927. In the summer of 1927 McShane entered graduate school at the University of Chicago, from which he received his Ph.D. in 1930 under the supervision of Gilbert Ames Bliss. He interrupted his studies during 1928-29 for financial reasons to teach at the University of Wichita. It was at Chicago that McShane’s long-standing interest in the calculus of variations began.

    20032003 TimoshenkoTimoshenko MedalMedal Presented to Professor L.B. Freund In recognition of Seminal contributions to the mechanics of dynamic fracture, seismology, and the mechanical behavior of thin films. Presented at The Applied Mechanics Division Banquet The 2003 International Mechanical Engineering Congress in Washington, DC November 18, 2003 Presiding: Pol D. Spanos ASME/AMD Chair 2003-2004 L. B. FREUND, Ph.D. Brown University Providence, RI r. Freund began his career at Brown University (Providence, R.I.) in 1967 as a postdoctoral research associate in the Ddivision of engineering. He joined the teaching faculty as assistant professor in 1969, and was promoted to associate professor in 1973 and professor in 1975. He served as chair of the Engineering Executive Committee (1979-83) and, in 1987, he was appointed as the Henry Ledyard Goddard University professor. He has held visiting appointments at Stanford University, California; Harvard University (Cambridge, Mass.); the California Institute of Technology, Pasadena; the University of California at Berkeley; and Jet Propulsion Laboratory (Pasadena, Calif). Freund’s early research focused on the dynamic response of materials to applied loading, an interest that evolved into a long-term study of dynamic fracture phenomena, including work on seismic source modeling, rupture of natural gas transmission lines, crack arrest in ship hulls and reactor pressure vessels, computational methods for dynamic fracture, the influence of crack tip plasticity on rapid crack growth and other materials issues. This effort culminated in the publication of a monograph, Dynamic Fracture Mechanics (Cambridge University Press, 1990). Freund continues to pursue several issues in this general area, including plastic bifurcation and ductile fragmentation of materials at high rates of deformation.
