Sidney H. Liebson (July 9, 1920[1] – February 7, 2017) received his Ph.D. from the University of Maryland in 1947.
Liebson received a US Navy award for developing the first equipment used to identify enemy radar.
In a significant test, his detectors validated the feasibility of making the hydrogen bomb.
At a time when electronics had not been able to make measurements with nanosecond accuracy, he developed several techniques to accomplish this accuracy for measuring organic fluorescence decay times and organic scintillation pulse widths by indirect means.
All modern GM tubes use his halogen-based quench gas.
