Biography

Roald Hoffmann (born Roald Safran; July 18, 1937) is a Polish-American theoretical chemist who won the 1981 Nobel Prize in Chemistry along with Kenichi Fukui for their work on understanding chemical reactions. Born in Zolochiv, Hoffmann survived the Holocaust as a child before moving to the United States. He went to Stuyvesant High School in New York City, then attended Columbia University and Harvard University, where he focused on theoretical chemistry.

Hoffmann's research involves using quantum mechanics to explore chemical bonding and molecular structure. He is best known for developing the Woodward-Hoffmann rules with Robert Burns Woodward. These rules predict the outcomes of electrocyclic reactions, cycloadditions, and sigmatropic rearrangements. They changed the field of organic chemistry by providing a way to understand reaction mechanisms based on orbital symmetry.

In addition to his scientific work, Hoffmann is also recognized as a writer and educator. He is the Frank H. T. Rhodes Professor of Humane Letters Emeritus at Cornell University, showcasing his interests that connect science and the humanities. He has written several books that mix chemistry with philosophy, as well as poetry and plays that explore the human side of scientific discovery. His TV series "The World of Chemistry" helped make science more accessible to the public.

Over his career, Hoffmann has received many awards for his work in chemistry and education, including the National Medal of Science (1983), the Priestley Medal (1990), and the Lomonosov Gold Medal (2011), among others from chemical societies worldwide. His contributions continue to be important in theoretical chemistry, especially in computational methods and understanding chemical bonding.

Before Fame

Born during a turbulent time in Eastern Europe, Hoffmann went through the chaos of World War II as a young child. His family was persecuted during the Holocaust, and he spent part of his early childhood in hiding. After the war, his family moved to the United States, where he started his formal education in New York City.

Hoffmann did very well at Stuyvesant High School, known for its strong science and math programs. He continued his studies at Columbia University, then went on to graduate work at Harvard University. There, he worked with leading chemists who greatly influenced his approach to theoretical chemistry and the use of quantum mechanics in chemical systems.
