In this interview, David Zierler, Oral Historian for AIP, interviews Charles Bennett, Bloomberg Distinguished Professor in the Department of Physics and Astronomy and in the Applied Physics Laboratory at the Johns Hopkins University. He recounts his childhood in suburban Washington, D.C., and he describes the influence of his father, who was a physicist with the National Bureau of Standards. He describes his early interests in radio waves and telescopes. He describes his decision to attend the University of Maryland on the basis of its excellent reputation in radio astronomy, and he discusses his interests in instrumentation and his work at the Clark Lake Radio Observatory. Bennett describes the circumstances regarding his decision to attend MIT for graduate school, where he worked with Bernie Burke on analyzing radio observatory data. He discusses his career at Goddard at NASA and his involvement in some of the major missions of the time, including COBE and WMAP. Bennett describes his decision to join the faculty at Hopkins, and the ways in which his research changed in an academic setting. He discusses his current interest in the Hubble constant measurement and the importance in conveying scientific concepts to the broader public. At the end of the interview, Bennett shares his thoughts on how the scientific community can continue to progress in areas relating to diversity and inclusivity in the field, and he relates that his sense of wonder at what can be learned by looking at the universe remains much the same as when he was a boy.
