Herbert Max Finlay Freundlich was a famous German chemist. He was born on January 28, 1880, in Charlottenburg, Germany. He passed away on March 30, 1941, in Minneapolis, USA. Freundlich was known for his important work in chemistry, especially with colloids. He was also a Foreign Member of the Royal Society.
Herbert Freundlich's father was of German Jewish background. His mother, whose maiden name was Finlay, came from Scotland. He had a younger brother named Erwin Finlay Freundlich, who also became a scientist.

A Career in Chemistry
Herbert Freundlich led a department at the Kaiser Wilhelm Institute for Physical Chemistry and Electrochemistry. This institute is now called the Fritz Haber Institute. He worked there from 1919 until 1933.
Facing Challenges
In 1933, the Nazi party came to power in Germany. Their rules meant that people who were not considered "Aryan" could not hold senior jobs. Because of this, Freundlich, who was Jewish, had to leave his position.
Moving to New Countries
After leaving Germany, Freundlich moved to England. He became a guest professor at University College London. Five years later, he moved again, this time to the United States. He accepted a professorship at the University of Minnesota. He lived in Minneapolis for two more years before he passed away.
Important Discoveries
Freundlich's main work focused on colloidal solutions. These are mixtures where tiny particles are spread throughout another substance. Think of milk, which is a colloid of fat particles in water. He studied how these particles clump together, a process called coagulation. He also researched how stable these solutions were.
Adsorption Studies
One of his most important papers was published in 1907. It was titled "Über die Adsorption in Lösungen," which means "On adsorption in solutions." Adsorption is when molecules stick to the surface of a solid or liquid. This is different from absorption, where molecules are soaked up. Freundlich's early work on adsorption is still very important today. Scientists continue to refer to his findings.
Notable Students
One of Freundlich's most famous students was Robert Havemann. Havemann later became a well-known colloid chemist in East Germany.
