This transcript is based on a tape-recorded interview deposited at the Center for History of Physics of the American Institute of Physics. The AIP's interviews have generally been transcribed from tape, edited by the interviewer for clarity, and then further edited by the interviewee. If this interview is important to you, you should consult earlier versions of the transcript or listen to the original tape. For many interviews, the AIP retains substantial files with further information about the interviewee and the interview itself. Please contact us for information about accessing these materials.

Please bear in mind that: 1) This material is a transcript of the spoken word rather than a literary product; 2) An interview must be read with the awareness that different people's memories about an event will often differ, and that memories can change with time for many reasons including subsequent experiences, interactions with others, and one's feelings about an event. Disclaimer: This transcript was scanned from a typescript, introducing occasional spelling errors. The original typescript is available.

Interview with Peter L. Bender, Senior Research Associate at the University of Colorado and the Joint Institute for Laboratory Astrophysics (JILA) in Boulder. Bender recounts his childhood in New Jersey, he describes his undergraduate focus in math and physics at Rutgers, and he explains his decision to pursue a graduate degree in physics at Princeton to work with Bob Dicke. He discusses his dissertation research on optical pumping of sodium vapor, which was suggested by Dicke as a means of doing precision measurements of atoms. Bender discusses his postdoctoral research at the National Bureau of Standards, where he focused on magnetic fields and he narrates the administrative and national security decisions leading to the creation of JILA in Boulder, where the laboratory would be less vulnerable to nuclear attack. He describes his work on laser distance measurements to the moon and his collaborations with NASA, and he discusses his long-term advisory work for the National Academy of Sciences and the National Research Council. Bender describes the origins of the NASA Astrotech 21 Program and the LISA proposal, he explains his more recent interests in massive black holes, geophysics and earth science, and he explains some of the challenges associated with putting optical clocks in space. At the end of the interview, Bender reflects on the central role of lasers in his research, and he explains the intellectual overlap of his work in astrophysics and earth physics, which literally binds research that is based both in this world and beyond it.
