Donald J. Cram

Donald J. Cram was a renowned American chemist who made significant contributions to the field of chemistry, particularly in developing techniques to understand and manipulate molecules. He is best known for inventing the concept of "host-guest chemistry," where larger molecules (hosts) can trap and hold smaller ones (guests), leading to new ways to analyze and design chemicals. His pioneering work earned him the Nobel Prize in Chemistry in 1987. Cram's research has advanced the understanding of molecular interactions, impacting areas like materials science, pharmaceuticals, and chemical synthesis.
