Interview with Jay Pasachoff, Field Memorial Professor of Astronomy at Williams College. Pasachoff discusses his childhood in New York City and his early interests in astronomy, telescopes and math. He recalls participating in a summer math program at Berkeley after his high school graduation, before he enrolled at Harvard as an undergrad. He recounts being invited to partake in observational research at Sacramento Peak Observatory, where he worked with Jacques Beckers and Bob Noyes. Pasachoff then explains his decision to continue at Harvard for his graduate studies, where Bob Noyes became his thesis advisor. He remembers finishing his PhD while also working at the Air Force Cambridge Research Laboratory, doing radio astronomy work. Pasachoff discusses the events that led to his postdoc at Caltech, and his subsequent move to Williams College. Throughout the interview, Pasachoff remembers many of the solar eclipses he has observed and his research surrounding them. He also discusses the many textbooks he has written over the years.

Covers her career in astronomy. Focuses on college education at Goucher, 1945-1948, and Harvard Graduate School from 1955; influence of Bart Bok and Cecilia Payne Gaposchkin. Positions at Naval Research Laboratory, Air Force Cambridge Research Laboratory; funding, satellite tracking, telescope for Cerro Tololo, Berkeley, 1965; Hat Creek. Discussions on radio astronomy in 1950s and 1970s; very large array telescopes; women in astronomy and search for alternatives. Also prominently mentioned are: William W. Campbell, Harold Ewen, Thomas Gold, Helen Dodson Prince; Harvard Radio Observatory, United States Air Force, Cambridge Research Laboratory of United States Air Force, and University of California at Berkeley.
Reviews Aarons' (b. October 3, 1921) career at AFCRL as a research physicist (1946-55), Chief of Radio Astronomy Branch (1955-72), and at AFGL as Chief of the Trans-ionospheric Propagation Branch and Senior Scientist at the Space Physics Lab (1972-81). Topics discussed include significant aspects of his role in the use of V-2s by Marcus O'Day for upper atmosphere research; his contact with O'Day and Menzel and the establishment of Sac Peak; the research mission of AFCRL; AFCRL's early interest in solar studies; and a comparison of present day research activities at AFGL and NRL.
