Sidney H. Liebson facts for kids
Sidney H. Liebson (born July 9, 1920 – died February 7, 2017) was an American scientist and inventor. He earned his Ph.D. (a high-level university degree) from the University of Maryland in 1947. His work helped improve important scientific tools and technologies.

Early Life and Education
Sidney H. Liebson was born on July 9, 1920. He was very interested in science and went on to study at the University of Maryland. In 1947, he completed his Ph.D. His main research for this degree was about how Geiger–Müller counters work. These devices are used to detect radiation.
Improving Radar Technology
After his studies, Liebson received an award from the US Navy. This was for his important work in creating the very first equipment that could identify enemy radar signals. This invention was a big step forward for national security.
Scientific Contributions
Liebson made several key contributions to science and technology throughout his career. His work often involved making very precise measurements and improving existing tools.
Developing Radiation Detectors
Liebson took part in important scientific tests in the Pacific Ocean. During these tests, he developed special radiation detectors. These detectors were used to measure the features of powerful new technologies. His detectors were so good that they helped confirm that it was possible to create the hydrogen bomb.
Super-Fast Measurements
In the past, it was very hard for electronic devices to measure things that happened in tiny fractions of a second, like nanoseconds (a nanosecond is one billionth of a second!). Liebson found new ways to make these super-fast measurements. He used indirect methods to measure how quickly certain organic materials glowed (called fluorescence) and how long their light pulses lasted (called scintillation).
The Halogen Gas Invention
One of Liebson's most famous inventions happened in 1947, while he was still working on his Ph.D. He discovered that using halogen gas inside Geiger–Müller tubes made them much better. This change meant the tubes could work with lower voltage, and they lasted much longer. Today, all modern Geiger–Müller tubes use his halogen-based gas. This shows how important and lasting his invention was.
Later Life
Sidney H. Liebson passed away on February 7, 2017. His inventions and scientific work continue to impact how we understand and measure the world around us.
