X-rays

Youth and family life in Turkish Armenia prior to turn of century; time at Yale Sheffield Scientific School and early research interests; World War I work for U.S. Signal Corp; teaching experience and associates at Sheffield School; his book on mechanics; experience at Cavendish Laboratory, 1914; impressions of Joseph J. Thomson, reaction to Niels Bohr's atomic theory. Trinity College in Hartford, state of physics department; his preoccupation with wartime plight of Armenians. Comments on philosophy of science, reaction at Yale University to the theory of relativity, hazards of x-rays, concepts of centrifugal force, indeterminacy and complementarity. Also prominently mentioned is Leigh Page.

Born July 19, 1915 in Cleveland, OH; family background and early childhood growing up in Cleveland; early interest in acoustics, the flute, electronics, and radio; graduated from high school in 1933; attended Case Institute of Technology, graduating with a B.S. in physics in 1937; moved to University of Illinois for graduate school, specialized in nuclear physics research (also maintained abiding interest in acoustics); thesis research on nuclear cross sections classified by wartime Manhattan Project; completed Ph.D. in 1941; awarded Westinghouse Research Fellowship in 1941 to work on wartime microwave electronics at corporate laboratories in Pittsburgh; collaborated with researchers at MIT Radiation Laboratory; concentrated on development of magnetrons and other high-power electron tubes; accepted full time position at Westinghouse in 1944; developed x-ray image amplifier, major innovation for medical fluoroscopy; transitioned into management positions initially overseeing electronics projects (and some nuclear physics work); graduatlly moved into senior management positions focusing on research strategy and policy; retired in 1980; continued work in acoustics field.

In this interview, E. T. Byram and T. A. Chubb discuss the Naval Research Laboratory's role in the history of x-ray astronomy. Topics discussed include: E. O. Hulburt; Ernie Krause; Richard Tousey; Herbert Friedman; Geiger counters; solar x-rays; Sam Lichtman; V-2 rockets; Viking rockets; Aerobee rockets; solar flares; Robert Kreplin; J. E. Kupperian; Julian Holmes; American Science and Engineering; P. C. Fisher.

This telephone interview deals with Bowyer’s research in non-solar x-ray astronomy while he worked at the Naval Research Laboratory in Washington, D.C. He discusses his functions as a member of a group of scientists, directed by Herbert Friedman, who performed numerous observations of cosmic x-ray sources in 1963 and after. Bowyer relates the competitive, spirit that existed between the NRL group and the Massachusetts Institute of Technology-American Science and Engineering, Inc. group that made the first conclusive observation of x-rays originating from outside the solar system.
