Geertruida Luberta de Haas-Lorentz (born November 20, 1885 – died 1973) was a smart Dutch physicist. She was the first person to study how tiny particles like electrons move randomly. This work is called "fluctuational analysis." Because of her research, she is known as the first woman to work on the theory of "electrical noise." This is about the small, unwanted changes in electric signals.

About Geertruida de Haas-Lorentz

Early Life and Family

Geertruida, also known as Berta Lorentz, was born in Leiden, Netherlands. Her father was Hendrik Lorentz, a famous physicist who won the Nobel Prize in 1902. Her mother was Aletta Catharina Kaiser. At the time Berta was born, her father was a professor of physics at the University of Leiden.

On December 22, 1910, Berta married Wander Johannes de Haas. He also became a professor of experimental physics in Leiden. They had two sons and two daughters together.

Education and Scientific Work

Berta studied physics at the University of Leiden. Her father was her teacher and helped her with her studies. In 1912, she earned her doctor's degree. Her main research was about "Brownian motion." This is the random movement of tiny particles in a liquid or gas. Imagine dust motes dancing in a sunbeam; that's a bit like Brownian motion.

After finishing her studies, Dr. de Haas-Lorentz taught physics. She worked at the Technical University of Delft. She also helped translate some of her father's important scientific writings into German.

Her most important work was studying how electrons move randomly, just like particles in Brownian motion. This research helped us understand "electrical noise." Her ideas are still used and talked about by scientists today.

Geertruida de Haas-Lorentz passed away in 1973 in Leiden, the same city where she was born.
