In this Oral History, Prof. Roger Tanner (University of Sydney) discusses his life and career in rheology with Gareth McKinley. Starting with discussion of his time growing up in England and working at the Bristol Aeroplane Company, attending Bristol University and then going to UC Berkeley on a King George VI Memorial Fellowship for a Master’s degree in control engineering. He describes the development of his interest in lubrication flows in bearings and first exposure to rheology through Frank Leslie and Arthur Lodge during his doctoral studies in Manchester, UK. He discusses in depth his work in Manchester, University of Sydney and Brown University as well as sabbaticals at the Rheology Research Center in Wisconsin and at the University of Delaware and time in academic administration as Pro-Vice Chancellor of Research.

He also discusses his time as president of the British Society of Rheology (1974-75) and also as inaugural president of the European Society of Rheology (1997), starting the Journal of Non-Newtonian Fluid Mechanics (1976), and the organization of the very successful Dynamics of Complex Fluids meeting (1996) at the Isaac Newton Institute at the University of Cambridge.
Interview with Willy Haeberli, Professor of Physics Emeritus at the University of Wisconsin in Madison, Wisconsin. Haeberli recounts his childhood in Basel, Switzerland, and he describes his experiences as a student during World War II. He discusses his early interest in physics and his decision to pursue nuclear physics at the University of Basel under the direction of Paul Huber. Haeberli describes his graduate research on the ionization of gasses by alpha particles, and he describes the circumstances leading to his subsequent postdoctoral job at the University of Wisconsin, where he was attracted to work with Raymond Herb in accelerator physics. He explains some of the scientific and cultural adjustments in order to settle in at Madison, and he describes the central questions of the structure of atomic nuclei that propelled nuclear physics at that time. He describes his subsequent research at Duke University before returning to Madison to join the faculty, he describes his many research visits to ETH Zurich, the Max Planck Institute, Fermilab, Saclay, and at DESY in Hamburg, and he offers insight on some of the differences in approach between American and European accelerator labs.

He discusses his work developing gas targets of pure spin polarized hydrogen and deuteron atoms, and he describes the critical support of the DOE and the NSF for this research. Haeberli shares his feelings on being elected to the National Academy of Sciences, and he explains his preference teaching undergraduates to graduate students. At the end of the interview, Haeberli describes how the department of physics at Wisconsin has changes over his decades of service, and he explains how only with the benefit of historical hindsight can one distinguish the truly important advances in the field.
Interview with Robert Jennings, retired since 2018 from the FDA’s Center for Devices and Radiological Health, where he was a research physicist.

At the end of the interview, Jennings surveys the fundamental developments that have advanced over the course of his forty-plus year career at FDA, his major contributions in tissue simulation science, and why he believes AI will become increasingly central to advances in medical imaging.
In this interview, David Zierler, Oral Historian for AIP, interviews Daniel Z. Freedman, Professor Emeritus of Applied Mathematics and Physics at MIT and long-term visiting professor at Stanford. Freedman explains his understanding of the term’s mathematical physics and physical mathematics, and he bemoans the broad decoupling of experiment and theory in physics. He recounts his upbringing in West Hartford, Connecticut, and he describes his undergraduate education at Wesleyan. Freedman describes his early attachment to theory and his graduate work at the University of Wisconsin, where he worked under the direction of Ray Sawyer on Regge poles.

He reflects on his interactions with Yang and he narrates the origins of supersymmetry, and shortly after, the origins of supergravity. Freedman explains what is “super” in supergravity, supersymmetry, and super-space, and he describes why the reality of supersymmetry must be true even if we lack the tools to see it. He explains his decision to move to MIT, and he connects the arc from the 1984 string revolution to the discovery of AdS/CFT in 1997. Freedman describes winning the Dirac medal and subsequently the Breakthrough Prize, which he understood as confirmation in the community about the importance of supergravity. At the end of the interview, Freedman connects his work to larger questions in cosmology and astrophysics, he expresses surprise by the increasing centrality of mathematics to physics, he explains his early work on neutrino scattering and why after 40 years, his original intuition has been vindicated.
