Roald Hoffmann (born Roald Safran; July 18, 1937) is a Polish-American theoretical chemist who won the 1981 Nobel Prize in Chemistry.
They arranged with a Ukrainian neighbor named Mykola Dyuk for Hoffmann, his mother, two uncles and an aunt to hide in the attic and a storeroom of the local schoolhouse, where they remained for eighteen months, from January 1943 to June 1944, while Hoffmann was aged 5 to 7. His father remained at the labor camp, but was able to occasionally visit, until he was tortured and killed by the Germans for his involvement in a plot to arm the camp prisoners.

They migrated to the United States on the troop carrier Ernie Pyle in 1949. Hoffmann visited Zolochiv with his adult son (by then a parent of a five-year-old) in 2006 and found that the attic where he had hidden was still intact, but the storeroom had been incorporated, ironically enough, into a chemistry classroom.
They have two children, Hillel Jan and Ingrid Helena. He is an atheist. ===Education and academic credentials=== Hoffmann graduated in 1955 from New York City's Stuyvesant High School, where he won a Westinghouse science scholarship.
He received his bachelor of arts degree at Columbia University (Columbia College) in 1958.
In 2009, a monument to Holocaust victims was built in Zolochiv on Hoffmann's initiative. ==Personal life== Hoffmann married Eva Börjesson in 1960.
He earned his master of arts degree in 1960 from Harvard University.
Hoffman has developed semiempirical and nonempirical computational tools and methods such as the extended Hückel method which he proposed in 1963 for determining molecular orbitals. With Robert Burns Woodward he developed the Woodward–Hoffmann rules for elucidating reaction mechanisms and their stereochemistry.
He went to Cornell in 1965 and has remained there, becoming professor emeritus. ==Scientific research== Hoffmann's research and interests have been in the electronic structure of stable and unstable molecules, and in the study of transition states in reactions.

He earned his doctor of philosophy degree from Harvard University while working under joint supervision of Martin Gouterman and subsequent 1976 Nobel Prize in Chemistry winner William N.
Roald Hoffmann (born Roald Safran; July 18, 1937) is a Polish-American theoretical chemist who won the 1981 Nobel Prize in Chemistry.
For this work Hoffmann received the 1981 Nobel Prize in chemistry, sharing it with Japanese chemist Kenichi Fukui, who had independently resolved similar issues.
