In this interview, David Zierler, Oral Historian for AIP, interviews Robert Cava, Russell Wellman Moore Professor of Chemistry at Princeton. He describes his dual appointment in the Princeton Materials Institute and he reflects on the distinctions between being a solid state and not a condensed matter chemist. Cava recounts his childhood in Brooklyn and the opportunities that led to his undergraduate admission to MIT. He discusses his studies in materials science, and his decision to stay on for a PhD to study crystallography and the properties of sulfide materials under the direction of Bernie Wuensch. Cava describes some of the advances in ceramics that was important to him, and he discusses his work on sodium electrolytes at MIT’s Lincoln Laboratory. He explains his decision to join the Sold State Chemistry Research Department Bell Labs, and he describes some of the exciting developments in ceramic superconductors and why superconductivity is a window onto the complexity of solids. Cava discusses the significance of the YCBO collaboration, he describes the impact of the breakup of Bell Labs and his subsequent decision to transfer to Princeton. He explains some of the cultural shifts that allowed Princeton to become more involved in applied science, and he discusses what he learned about academic politics during his time as chair of the Department of Chemistry. Cava discusses his career-long search for new compounds and studying transition metal oxides, and he describes the many advances in thermoelectronics. At the end of the interview, Cava reflects on his scientific contributions, and he emphasizes the value in science of being a good listener.
