Spectrum analysis

This interview traces Brunk's career in engineering with the National Advisory Committee for Aeronautics (NACA), Lewis Research Center (formerly Lewis Flight Propulsion Laboratory), NASA and NASA Headquarters.  The discussion begins with an overview of his family background and his education at Case Institute of Technology, followed by his work in supersonic aerodynamics for NACA.  The interview primarily examines Brunk's role in and perceptions of the development of planetary ground-based astronomy during his tenure at NASA Headquarters, as Program Chief of Planetary Astronomy.  Topics discussed include: telescope innovations at different observatories; problems and techniques in ground-based observation; exploration of Mars; the Planetary Patrol program at Lowell Observatory; his membership to the American Astronomical Society; and general perceptions of NASA's role in ground-based astronomy.  Other affiliations and contacts discussed include: Jason Nassau, Nancy Roman, Urner Liddel, and Gerard Kuiper.

This interview surveys Baum's career as a physicist at the Naval Research Laboratory (NRL) and astronomer at Mt. Wilson and Palomar Observatories.  After sketching Baum's early life, the discussion concentrates on Baum's role in the development of spectroscopy research at NRL, specifically his work on the UV spectrum of the sun - including the first successful UV spectra of the sun. Aspects of his experience in experimentation with V-2s and Aerobees, and his thesis research on rockets at CALTECH (PhD, 1950, physics) are also explored.  Additional topics discussed include: Optics Division, NRL; White Sands Proving Ground (NM); relationships with, and costs and descriptions of Baird Atomic; V-2 missile experiments, development and launch; meetings with Werner Von Braun; and contacts with R.W. Wood, J. Strong, Lyman, Stockbarger, and Tousey.
