In this interview, astronomer Peter Jakobsen discusses his involvement with the Hubble and James Webb Space Telescopes during his life-long career at the European Space Agency (ESA). He recounts his early childhood growing up in Cincinnati and later returning to his hometown in Denmark, where he attended the University of Copenhagen. He reflects on his time at the Laboratoire d’Astronomie Spatiale in Marseille during his Master’s degree and his time at Berkeley working in the Space Astrophysics Group led by Stu Bowyer. Jakobsen discusses his job as Project Scientist for the European involvement in the Hubble Space Telescope, the development of ESA’s Faint Object Camera, and the discovery of the spherical aberration. He details his role in the development of COSTAR and Hubble’s repair missions. Jakobsen recalls being skeptical of the initial talks for the Next Generation Space Telescope, but later taking on a key role for the European side of the project. He also recalls the competition between the contractors working on the initial design phase for NIRSpec. Jakobsen gives an account of his last years at ESA and the conditions that led to his retirement from the agency in 2011. He gives his perspective on Webb’s launch and reflects on the budget and schedule delay concerns. He discusses his post-retirement technical work and the guaranteed observing time program for JWST. Towards the end of the interview, Jakobsen describes his current focus with NIRSpec and his reflections on the future of astronomy.

In this interview, former Niels Bohr Archive Director Finn Aaserud reflects on his career, including his work as a postdoctoral historian at the American Institute of Physics. Aaserud discusses his education in physics at the University of Oslo and his decision to focus his work on the history of Max Planck’s concept of the quantum. He recalls his decision to pursue a degree in the history of science at Johns Hopkins University, with Russell McCormmach as his advisor, and his research on Niels Bohr’s leadership of the Institute for Theoretical Physics at the University of Copenhagen in the 1930s. He reflects that some scholars, particularly those invested in Bohr’s image as an intellectual, objected to the portrait he presented of Bohr as a skilled fundraiser. Aaserud recalls his move to AIP and his experiences working on the history of the JASON science advisory group. The interview concludes with Aaserud’s memories of receiving the offer to direct the Niels Bohr Archive in Copenhagen, his experiences in that role, his editing of Bohr’s collected works, and the history of the strong relationship between the archive and the Center for History of Physics and Niels Bohr Library & Archives at AIP.

This interview was conducted as part of the Archives for the History of Quantum Physics project, which includes tapes and transcripts of oral history interviews conducted with ca. 100 atomic and quantum physicists. Subjects discuss their family backgrounds, how they became interested in physics, their educations, people who influenced them, their careers including social influences on the conditions of research, and the state of atomic, nuclear, and quantum physics during the period in which they worked. Discussions of scientific matters relate to work that was done between approximately 1900 and 1930, with an emphasis on the discovery and interpretations of quantum mechanics in the 1920s. Also prominently mentioned are: Bichowsky, Raymond Thayer Birge, Walker Bleakney, Niels Henrik David Bohr, Ferdinand Graft Brickwedde, Compton, Albert Einstein, Samuel Abraham Goudsmit, Werner Heisenberg, Richard Jesse, Edwin Crawford Kemble, Hendrik Anthony Kramers, Ralph de Laer Kronig, Gilbert Newton Lewis, Hendrik Antoon Lorentz, Robert Sanderson Mulliken, J. Robert Oppenheimer, Linus Pauling, Arthur Edward Ruark, John Clarke Slater, Arnold Sommerfeld, George Eugene Uhlenbeck, Robert Williams Wood; Columbia University, Johns Hopkins University, Kobenhavns Universitet, University of California at Berkeley, and University of Montana.
