In this interview, AIP Oral Historian David Zierler interviews Zachary Fisk, Professor Emeritus in the Department of Physics and Astronomy, University of California, Irvine. Fisk recounts his early exposure to physics from his father, who worked as physicist at Bell Labs. Fisk discusses his interest in chemical bonding as an undergraduate at Harvard, and his admiration for professors Purcell and Ramsey. He describes his decision to leave Harvard and take a job at Los Alamos, where he attended colloquia from visitors including Rabi and Bethe. Fisk discusses his reapplication and graduation from Harvard, and his decision to begin graduate work at UC San Diego where he studied the Kondo effect and rare earth impurities. Following graduate school, Fisk describes his experiences as a postdoc at Imperial College in London, his assistant professorship at the University of Chicago, and his long-term joint appointments at UC San Diego and Los Alamos, where he worked on heavy-fermion superconductors and growing crystals from molten metal fluxes. Fisk describes his motivations for joining the Magnet Lab group at Florida State University, and then his later work back in California at UC Davis and then UC Irvine. At the end of the interview, Fisk describes his ongoing fascination with superconductivity and why his early interests in chemical compounds has remained a constant throughout his career.
