. He is also well known for an insight into the nature of supercooled liquids which is now known as Kauzmann's paradox. At Princeton, Kauzmann was the David B. Jones Professor Emeritus of Chemistry. He chaired the Department of Chemistry (1964 to 1968) and the Department of Biochemical Sciences (1980 to 1981).

. Following his Ph.D., Kauzmann had a two-year postdoctoral appointment in Pittsburgh as a Westinghouse Research Fellow, in the laboratory led by Edward U. Condon. It was during this period that Kauzmann wrote his now classic paper on supercooled liquids and glasses that contained the Kauzmann paradox. At the end of this fellowship, with the U.S. fighting WWII, Kauzmann joined the U.S. government's National Defense Research Council laboratory in Bruceton, Pennsylvania

) plutonium bomb that was dropped on Nagasaki, Japan. Kauzmann witnessed the Trinity test on July 16, 1945, and his memories were recorded in a newspaper article. Fifty years later, Kauzmann discussed why he worked on the atomic bomb:

"But there was another, even stronger reason that many of us felt justified our working as hard as we could on the bomb. It was felt that if it were possible to make atomic bombs, somewhere, someday, someone would figure out how to do it and some country would proceed to make them. If this were done after World War II was over, the bomb would very likely be made as a secret weapon. This would inevitably lead to World War III. Therefore, there were strong reasons for trying to make the bomb - and use it - before the end of World War II. The people of the world would then know the terrible thing that could be unleashed if there were a World War III. And the politicians could then be encouraged to try to do something about preventing World War III."

In 1946, Kauzmann returned to Princeton as an Assistant Professor of Chemistry and remained on the Princeton Faculty throughout his long academic career. His work was centered in the area of biophysical chemistry
