Mildred Allen was born in Massachusetts in 1894, the elder of two daughters of an MIT professor of civil engineering who had met her mother while working in New Mexico. She graduated from Vassar College in 1916 with training in mathematics and physics. Her Ph.D. in physics (1922) was granted by Clark University where she studied with A. G. Webster, but her thesis research was one at MIT. She taught at Mt. Holyoke, Wellesley and Oberlin Colleges during the 1920s and early 30s, as well as studying further at the University of Chicago and Yale. She did research at the Bartol Foundation, 1927-30, and at Harvard University, 1931-33. She then taught at Mt. Holyoke from 1933 until her retirement in 1959. Since then she has done additional research, most recently (paper published 1971) on the behavior of torsion pendulums especially during solar eclipses.
In this interview Pierre Demarque discusses topics such as: his early interest in astronomy; listening to radio lectures by Fred Hoyle; study at the University of Toronto; interest in cosmology; work with Leonard Searle; master's thesis on stellar structure; influence of Searle and J. Beverly Oke; move to the United States and Louisiana State University; University of Illinois and the influence of Ivan King; Ludwig Biermann; George McVittie; going to the University of Chicago and contact with Chandrasekhar; stellar evolution; Yerkes Observatory; leaving Chicago for Yale University; Walter Baade philosophy of studying cosmology; globular clusters; John Eddy's work on solar variability; stellar populations and galaxy evolution.
This interview is concerned primarily with two periods in the life of Libby (1927-1940 and 1945-1954). After briefly discussing his early life and education, considerable attention is focused upon Libby's undergraduate, graduate, and post-graduate years (1927-1940) at the University of California, Berkeley. Major topics included are: growth of Berkeley science; Gilbert Lewis, Wendell Latimer and Ernest Lawrence; Libby's development of low-level counters; radiochemistry and discovery of isotopes; cross-disciplinary collaboration; Libby's interest in carbon-14; association with Samuel Ruben and Martin Kamen; hot atom chemistry and nuclear isomerism; Libby's experiences at Princeton during 1940-1941 (hot atom chemistry, development of heterogeneous catalysis and research on tritium) and his work on the chemistry of the diffusion process during WWII at Columbia University (Manhattan Project) are mentioned; the other major portion of the interview concentrates on Libby's development of the radiocarbon dating technique at the University of Chicago (1945-1954); special attention is devoted to: measurement of half-life of carbon-14; importance to Libby of Harold Urey; secrecy policy; collaboration with Aristid von Grosse, James Arnold and Ernest Anderson; improved counting technologies; first contacts with archaeologists; Viking Fund and cross-disciplinary collaboration; communicating ideas; Sunshine Project and fallout; AEC appointment; concluding remarks.
