The details (from wikipedia)


Roald Hoffmann (born Roald Safran; July 18, 1937) is an 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, in Ithaca, New York.

Early life

Escape from the Holocaust

Roald Hoffmann (2015)

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 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.

Most of the rest of the family perished 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 married Eva Börjesson in 1960. They have two children, Hillel Jan and Ingrid Helena. 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. 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. 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 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. 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 has investigated the structure and reactivity of both organic and inorganic molecules, and examined problems in organo-metallic and solid-state chemistry. Hoffman has developed semiempirical and nonempirical computational tools and methods such as the extended Hückel method for determining molecular orbitals, which he proposed in 1963.

With Robert Burns Woodward he developed rules for elucidating reaction mechanisms (the Woodward–Hoffmann rules). 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. For this work Hoffmann received the 1981 Nobel Prize in chemistry, sharing it with Japanese chemist Kenichi Fukui, who had independently resolved similar issues. (Woodward was not included in the prize, which is given only to living persons.) 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!"

Artistic interests

The World Of Chemistry with Roald Hoffmann

In 1988 Hoffmann became the host of the 26-program series by Annenberg/CPB, The World of Chemistry, opposite series demonstrator Don Showalter. While Hoffman introduced ideas and concepts, Showalter provided a series of demonstrations and other visual representations to help students and viewers to understand the information.

Entertaining Science

Since the spring of 2001, Hoffmann has been the host of the monthly series Entertaining Science at New York City's Cornelia Street Cafe, which explores the juncture between the arts and science.


He has published books on the connections between art and science: Roald Hoffmann on the Philosophy, Art, and Science of Chemistry and Beyond the Finite: The Sublime in Art and Science.


Hoffmann is also a writer of poetry. His collections include The Metamict State (1987, ISBN 0-8130-0869-7), Gaps and Verges (1990, ISBN 0-8130-0943-X), and Chemistry Imagined, co-produced with artist Vivian Torrence.


He co-authored with Carl Djerassi the play Oxygen, about the discovery of oxygen and the experience of being a scientist. Hoffman's play, "Should’ve" (2006) about ethics in science in art, has been produced in workshops; as has a play based on his experiences in the holocaust, "We Have Something That Belongs to You" (2009).

Nobel Prize in Chemistry

In 1981, Hoffmann received the Nobel Prize in Chemistry, which he shared with Kenichi Fukui "for their theories, developed independently, concerning the course of chemical reactions".
