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 William Marciano, Senior Physicist at Brookhaven National Laboratory. Marciano recounts his upbringing in Brooklyn and his early interests in science, and he describes his undergraduate work at RPI and then NYU. He explains his decision to remain at NYU for his graduate research to study under the direction of Alberto Sirlin, and his thesis research on dimensional regularization. Marciano discusses his postdoctoral appointment at Rockefeller University where he worked on the SU(5) model of Grand Unification, and the opportunities that led to his promotion there to a faculty position. He explains his short tenure at Northwestern before joining Brookhaven, where kaon physics was taking center stage, and where ISABELLE was being built. Marciano discusses the origins of the Lab's g-2 experiment, and he compares the demise of ISABELLE to that of the SSC, for which he served on the program advisory committee. He describes the success of RHIC, and he discusses his research focus on muon and neutrino physics for the Lab's AGS program. Marciano explains his proposal that led to DUNE at Fermilab and he surveys his long record of advisory work for the HEPAP community and how the United States has contributed to the LHC. He reflects on winning the Sakurai prize and his contributions in establishing the validity of the Standard Model at the level of its quantum corrections. Marciano describes his recent work in dark physics, and he surveys the current state of play in muon physics and the Intensity Frontier. At the end of the interview, Marciano compares the diffuse network of the U.S. National Lab system to the centrality of CERN in Europe, and he explains why his work on DUNE and CP violation has been so personally meaningful.
