Donald J. Cram

Donald J. Cram was born on April 22, 1919, in Chester, Vermont, USA. He grew up in the small town of Brattleboro, Vermont. Cram would go on to become a notable chemist and a specialist in stereochemistry and the study of large molecules. His academic career and research were deeply influential in the field of organic chemistry. Cram's work laid the foundation for many developments in molecular chemistry, notably in the area of host-guest chemistry.

In 1947, Donald J. Cram joined the faculty of the University of California, Los Angeles (UCLA) as an assistant professor. Over the years, he worked his way through the academic ranks, eventually becoming a full professor. During his time at UCLA, Cram conducted significant research into organic chemistry and taught many students. He was known for his dedication to his subject and his dynamic teaching style, influencing generations of chemists.

In 1957, Donald J. Cram published his work on what is now known as Cram's Rule, a significant advancement in the field of stereochemistry. Cram's Rule addresses how nucleophiles add to carbonyl groups and predicts the preferred stereochemistry of products resulting from such reactions. This work was critical in understanding how to control and predict chemical reactions, paving the way for advancements in the synthesis of complex molecules.

On October 14, 1987, Donald J. Cram was awarded the Nobel Prize in Chemistry along with Jean-Marie Lehn and Charles Pedersen. The prize was given for their development and use of molecules with highly selective structure-specific interactions, which was a major milestone in the field of supramolecular chemistry. Cram's work in creating host-guest chemistry scenarios was pivotal in this achievement, contributing to the understanding of molecular interactions.

Donald J. Cram passed away on June 17, 2001, in Palm Desert, California, USA. He left behind a rich legacy in the field of chemistry, particularly through his groundbreaking work in stereochemistry and supramolecular chemistry. His contributions were recognized internationally, and his influence continues to be felt in research and academic circles. Cram's impact on the field of chemistry endures through the numerous scientists he mentored and inspired.
