Timeline
Roald Hoffmann (born Roald Safran; July 18, 1937) is a Polish-American theoretical chemist who won the 1981 Nobel Prize in Chemistry.
He has also published plays and poetry.
He is the Frank H. T. Rhodes Professor of Humane Letters Emeritus at Cornell University.
Hoffmann was born in Złoczów, Poland (now Zolochiv, Ukraine), to a Polish-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 extermination camps, the family bribed guards to allow an escape.
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.
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 Hoffmann 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.
In 1944 they moved to Kraków where his mother remarried.
They adopted her new husband's surname Hoffmann.
Most of the rest of the family was killed in the Holocaust, though one grandmother and a few others survived.
They migrated to the United States on the troop carrier Ernie Pyle in 1949.
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.
Hoffmann married Eva Börjesson in 1960.
They have two children, Hillel Jan and Ingrid Helena.
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.
They realized that chemical transformations could be approximately predicted from subtle symmetries and asymmetries in the electron orbitals of complex molecules.
Their rules predict differing outcomes, such as the types of products that will be formed when two compounds are activated by heat compared with those produced under activation by light.
He went to Cornell in 1965 and has remained there, becoming professor emeritus.
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 has investigated the structure and reactivity of both organic and inorganic molecules, and examined problems in organo-metallic and solid-state chemistry.
(Woodward was not included in the prize, which is given only to living persons, although he had won the 1965 prize for other work.) In his Nobel Lecture, Hoffmann introduced the isolobal analogy for predicting the bonding properties of organometallic compounds.
Some of Hoffman's most recent work, with Neil Ashcroft and Vanessa Labet, examines bonding in matter under extreme high pressure.
"What gives me the greatest joy in this work? That as we tease apart what goes on in hydrogen under pressures such as those that one finds at the center of the earth, two explanations subtly contend with each other ... [physical and chemical] ... Hydrogen under extreme pressure is doing just what an inorganic molecule at 1 atmosphere does!"
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. Lipscomb, Jr. Hoffman worked on the molecular orbital theory of polyhedral molecules.
Under Lipscomb's direction the Extended Hückel method was developed by Lawrence Lohr and by Roald Hoffmann.
This method was later extended by Hoffmann.
For this work Hoffmann received the 1981 Nobel Prize in chemistry, sharing it with Japanese chemist Kenichi Fukui, who had independently resolved similar issues.
In 1988 Hoffmann became the series host in a 26-program PBS education series by Annenberg/CPB, The World of Chemistry, opposite with series demonstrator Don Showalter.
While Hoffmann introduced a series of concepts and ideas, Showalter provided a series of demonstrations and other visual representations to help students and viewers to better understand the information.
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.
In 2009, a monument to Holocaust victims was built in Zolochiv on Hoffmann's initiative.
