William Nunn Lipscomb Jr. (December 9, 1919 – April 14, 2011) was an American chemist and Nobel Laureate renowned for his work on the structure and bonding of boranes, which are compounds of boron and hydrogen. His research significantly advanced the understanding of chemical bonds and the electronic structure of molecules. Lipscomb's contributions to chemistry were recognized with the Nobel Prize in Chemistry in 1976 "for his studies on the structure of boranes illuminating problems of chemical bonding."

Early Life and Education

William Nunn Lipscomb Jr. was born in Cleveland, Ohio, but spent most of his early life in Lexington, Kentucky. He developed an interest in chemistry and music at a young age, playing the clarinet and conducting chemical experiments in a home laboratory. Lipscomb attended the University of Kentucky, where he received his Bachelor of Science degree in Chemistry in 1941. He then went on to earn his Ph.D. in Chemistry from the California Institute of Technology (Caltech) in 1946, where he studied under Linus Pauling, another Nobel Laureate.

Career and Research

After completing his Ph.D., Lipscomb held positions at the University of Minnesota before moving to Harvard University in 1959, where he spent the majority of his academic career. At Harvard, he established a research group that made significant contributions to the field of inorganic chemistry, particularly in the study of boranes. Lipscomb's work elucidated the three-dimensional structures of boranes using X-ray crystallography, revealing insights into their bonding that were contrary to the then-prevailing theories. His research helped to lay the groundwork for the development of molecular orbital theory, which has become a fundamental concept in chemistry.

Lipscomb was also interested in the enzyme ribonuclease A and conducted pioneering studies on its structure and mechanism of action. His work in this area contributed to the broader understanding of the relationship between the structure and function of enzymes.

Awards and Honors

In addition to the Nobel Prize, Lipscomb received numerous other awards and honors throughout his career, including the National Medal of Science in 1971, the Priestley Medal in 1990, and election to the National Academy of Sciences. He was also a member of the American Academy of Arts and Sciences and the American Philosophical Society.

Legacy

William N. Lipscomb Jr.'s legacy in the field of chemistry is marked by his groundbreaking work on the structures and bonding mechanisms of boranes, as well as his contributions to the understanding of enzyme action. His research has had a lasting impact on the field, influencing subsequent generations of chemists and advancing the development of new materials and drugs. Lipscomb was not only a distinguished scientist but also a beloved teacher and mentor, remembered for his wit, kindness, and dedication to his students.

Personal Life

Lipscomb was known for his sense of humor and love of music, often playing the clarinet at scientific gatherings. He was married to Mary Adele Sargent until her death in 1989 and had three children. Lipscomb passed away on April 14, 2011, in Cambridge, Massachusetts.
