Hans Georg Dehmelt (born September 9, 1922 – died March 7, 2017) was a brilliant German-born American physicist. He won the Nobel Prize in Physics in 1989. He shared this important award for helping to create a special technique called the "ion trap" with Wolfgang Paul. This method allows scientists to study tiny particles like electrons with incredible accuracy.
Dehmelt passed away on March 7, 2017, in Seattle, Washington, at the age of 94.

Who Was Hans Georg Dehmelt?
Hans Georg Dehmelt was a very important scientist who made big discoveries in the world of physics. He was born in Görlitz, Germany, in 1922. Later, he moved to the United States and became an American citizen. He worked at famous universities like the University of Washington and Duke University.
His Amazing Discoveries
Dehmelt is best known for his work on something called the ion trap. Imagine trying to catch and hold something incredibly small, like a single electron, to study it. That's what an ion trap helps do!
He shared the Nobel Prize in Physics in 1989 with another scientist, Wolfgang Paul. They were honored for developing this amazing ion trap technique. Another scientist, Norman Foster Ramsey, also received part of the prize that year for different but related work.
What is an Ion Trap?
An ion trap is a special device that uses electric and magnetic fields to hold tiny charged particles, called ions, in one place. Think of it like an invisible cage made of energy. This allows scientists to study these particles for a long time without them touching anything. When particles touch other things, they can change, making them harder to study accurately.
Measuring the Electron's G-Factor
One of the most important things Dehmelt used the ion trap for was to measure the "g-factor" of an electron with extreme precision. The g-factor is a special number that tells scientists about how an electron behaves, especially how it spins and interacts with magnetic fields. Measuring this number very accurately helps us understand the fundamental rules of the universe. It's like getting a super-precise measurement of a tiny, tiny spinning top!
His work helped prove some of the most important theories in physics, like quantum electrodynamics, which explains how light and matter interact.
