He is best known for his work on the structure of [[cyclohexane]] and its derivatives, which earned him the [[Nobel Prize in Chemistry]] in 1969, shared with [[Derek Barton]].<br />
<br />
== Early Life and Education ==<br />
Odd Hassel was born in [[Kristiania]], now known as [[Oslo]], [[Norway]]. He was the son of Ernst Hassel, a gynecologist, and Mathilde Klaveness. Hassel attended the [[University of Oslo]], where he studied chemistry and graduated in 1920. He then pursued further studies in [[Germany]], working under the guidance of [[Peter Debye]] at the [[University of Munich]].<br />
<br />
== Academic Career ==<br />
Upon returning to Norway, Hassel joined the [[University of Oslo]] as a lecturer in 1925. He became a professor of physical chemistry in 1934, a position he held until his retirement in 1964. During his tenure, Hassel focused on the study of molecular structures using [[X-ray crystallography]] and other techniques.<br />
<br />
== Research and Contributions ==<br />
Hassel's most significant contribution to chemistry was his research on the [[conformation]] of [[cyclohexane]] and its derivatives. He demonstrated that cyclohexane can exist in different conformations, such as the chair and boat forms, which have different energy levels and stability. This work was crucial in understanding the three-dimensional structure of organic molecules and their chemical behavior.<br />
<br />
Hassel's research laid the foundation for the field of [[stereochemistry]] and had a profound impact on the development of [[organic chemistry]]. His findings were instrumental in the study of [[reaction mechanisms]] and the design of [[pharmaceuticals]].<br />
<br />
== Nobel Prize ==<br />
In 1969, Odd Hassel was awarded the [[Nobel Prize in Chemistry]] along with [[Derek Barton]] for their contributions to the development of the concept of conformation and its application in chemistry. The Nobel Committee recognized their work as a major advancement in the understanding of molecular structures.<br />
<br />
== Personal Life ==<br />
Odd Hassel was known for his modesty and dedication to science. He remained active in research and academia throughout his life. Hassel passed away on 11 May 1981 in [[Oslo]], leaving behind a legacy of significant scientific contributions.<br />
<br />
== Legacy ==<br />
Odd Hassel's work continues to influence the field of chemistry, particularly in the areas of [[stereochemistry]] and [[organic chemistry]]. His research on molecular conformations remains a fundamental concept in the study of chemical structures and reactions.<br />
