Roald Hoffmann (born Roald Safran; July 18, 1937) is an American theoretical chemist who won the 1981 Nobel Prize in Chemistry. He is the Frank H. T. Rhodes Professor of Humane Letters, Emeritus, at Cornell University, in Ithaca, New York.
Escape from the Holocaust
Hoffmann was born in Złoczów, Poland (now Ukraine), to a Jewish family, and was named in honor of the Norwegian explorer Roald Amundsen. His parents were Clara (Rosen), a teacher, and Hillel Safran, a civil engineer. After Germany invaded Poland and occupied the town, his family was placed in a labor camp where his father, who was familiar with much of the local infrastructure, was a valued prisoner. As the situation grew more dangerous, with prisoners being transferred to liquidation camps, the family bribed guards to allow an escape and arranged with a Ukrainian neighbor named Mikola Dyuk for Hoffman, 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 Hoffman 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. When she received the news, his mother attempted to contain her sorrow by writing down her feelings in a notebook her husband had been using to take notes on a relativity textbook he had been reading. While in hiding his mother kept Hoffman entertained by teaching him to read and having him memorize geography from textbooks stored in the attic, then quizzing him on it. He referred to the experience as having been enveloped in a cocoon of love.
Hoffman 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. In 2009, a monument to Holocaust victims was built in Zolochiv on Hoffmann's initiative.
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. He earned his Master of Arts degree in 1960 from Harvard University. He earned his Doctor of Philosophy degree from Harvard University while working under direction of subsequent 1976 Nobel Prize in Chemistry winner William N. Lipscomb, Jr. Under Lipscomb's direction the Extended Hückel method was developed by Lawrence Lohr and by Roald Hoffmann. This method was later extended by Hoffmann. He went to Cornell in 1965 and has remained there, becoming professor emeritus.
"From a chemist's point of view, the surface or interior of a star…is boring—there are no molecules there." – Roald HoffmannSee also: Molecules in stars
The World Of Chemistry with Roald Hoffmann
Hoffmann is also a writer of poetry published in two collections, The Metamict State (1987, ISBN 0-8130-0869-7) and Gaps and Verges (1990, ISBN 0-8130-0943-X), and of books explaining chemistry to the general public. Also, he co-authored with Carl Djerassi the play Oxygen, about the discovery of oxygen, but also about what it means to be a scientist and the importance of process of discovery in science.
