Tom W. Bonner
Tom Wilkerson Bonner (19 October 1910, Greenville, Texas – 6 December 1961 Houston, Texas) was an American experimental physicist who developed important instruments and techniques for neutron physics and nuclear physics (Bonner sphere).
==Biography==
Bonner earned his bachelor's degree in physics from SMU in 1931 and his PhD from Rice University in 1934. In 1934–1936 he was a National Research Council fellow at Cal Tech. At Rice University he became an instructor in 1936, a professor in 1945, and chair of the physics department in 1947. In the academic year 1938–1939 he was a Guggenheim fellow. From 1941 to 1946 he did radar research at the MIT Radiation Lab. Bonner was an associate editor of the ''Review of Scientific Instruments'' in 1946–1949 and in 1952–1955. He was an associate editor of ''Physical Review'' from 1951 until his death. In 1959 he was elected a member of the National Academy of Sciences. In 1964 the Tom W. Bonner Prize in Nuclear Physics was established in his memory.
He did important work in the development of high-pressure cloud chambers for the study of neutrons produced by accelerators. He invented a neutron-counter-ratio technique for the determination of neutron emission thresholds. He also invented a sphere-moderated neutron spectrometer.〔〔〔Bramblett, Richard L., Ewing, Ronald I., & Bonner, T. W. (1960). A new type of neutron spectrometer.

In 1937 he married Jara Prasilova; they had three children.〔 On 6 December 1961, at the age of 51 Bonner died in Houston, Texas of acute myocardial infarction.
