Interview with George Withbroe, retired science program director at NASA. Withbroe provides an overview of his childhood in Wisconsin where he enjoyed hunting and archery with his family. He discusses his undergraduate studies at MIT, which he remembers as being a highly competitive environment. Withbroe explains the impact of Sputnik on his interest in space science, leading him to pursue graduate studies in astronomy at the University of Michigan. He recalls discovering the joy of teaching during this time, as well as a memorable summer job at the NASA Lewis Research Center (now Glenn Research Center). Withbroe then describes his postdoctoral position at Harvard, working on the satellite program and the Orbiting Solar Observatories. He recounts his transition to the Smithsonian Astrophysical Observatory and his involvement in Skylab. Withbroe discusses going back to Harvard where he served as director of the Solar and Stellar Physics Division, before moving to NASA as the Director of the Space Physics Division. Withbroe covers topics such as securing funding for research, collaborations with the international scientific community, and the importance of diversity in science. He discusses his retirement from NASA and continuing his research at George Mason University. The interview concludes with Withbroe’s reflections on the many advisory committees he has served on, as well as his thoughts on the relationship between religion and science. 

Dr. George Doschek, retired scientist at the Naval Research Laboratory (NRL), is interviewed at the American Center for Physics in College Park, Maryland, by Ryan Hearty, oral history fellow at the American Institute of Physics. Doschek describes his early life in Pittsburgh and later career, spanning five decades, at the NRL in Washington, DC. Subjects include: Doschek’s childhood in Pittsburgh, growing up in a household supportive of music and science; undergraduate and doctoral studies at the University of Pittsburgh; coming to NRL and early activities in solar physics; work on spectroscopy at NRL, including on the missions OSO-1 to OSO-8, the 11 SOLRAD satellites, Skylab and the Apollo Telescope Mount (ATM), the P78-1 spacecraft, Yohkoh, and Hinode; and managing the Solar-Terrestrial Relationships Branch.

Interview with Loren Acton, American physicist and astronaut. Acton recounts his childhood in rural Montana and his decision to study engineering physics at Montana State University. He describes becoming interested in geophysics, leading him to pursue graduate school at the University of Colorado. Acton recalls his graduate work at the Lockheed Pao Alto Research Laboratory, working on his first solar x-ray experiment. He discusses his involvement in the astrogeophysics department at Colorado and his work on solar radiation satellites at the Naval Research Laboratory. Acton stayed at Lockheed upon completing his doctorate, and he describes his work on projects that employed instruments carried on rockets and satellites. He reflects on his exciting appointment as a payload specialist on the space shuttle, flying in 1985. Acton then turns to his time at Goddard Space Flight Center working on the Solar Max Mission, and he also discusses his collaboration with Japanese scientists on the Spacelab 2 mission. He discusses his return to Montana State University to help form the solar physics program. The interview concludes with Acton’s reflections on running for elected office and the role of scientists in politics. 

In this interview, Jon Phillips, Assistant Oral Historian for AIP, interviews Peter Gilman, Senior Scientist Emeritus in the High Altitude Observatory at the National Center for Atmospheric Research. Gilman recounts his early interest and education in meteorology and introduction to solar physics as an undergraduate, and his graduate research on solar dynamics with Victor Starr at MIT. He describes his early work at the University of Colorado and his move to, and rapid ascent at the National Center for Atmospheric Research. Gilman discusses his leadership role as Director of NCAR’s Advanced Study Program, and his own ongoing research in magnetohydrodynamics and helioseismology, followed by an overview of the history of NCAR, the High Altitude Observatory, and the relocation of the National Solar Observatory to Boulder. Gilman goes on to discuss the state of solar dynamo theory and solar-cycle activity predictions, in particular the predictions for solar cycles 24 and 25. The last portion of the interview focuses on the many “firsts” Gilman contributed to the field, particularly in magnetohydrodynamic modeling of the sun.
