:Roald Hoffmann

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.{{cite web |url=http://science.howstuffworks.com/dictionary/famous-scientists/chemists/roald-hoffmann-info.htm |title=Roald Hoffmann |publisher=HowStuffWorks |access-date=October 4, 2013 |url-status=live |archive-url=https://web.archive.org/web/20131005015520/http://science.howstuffworks.com/dictionary/famous-scientists/chemists/roald-hoffmann-info.htm |archive-date=October 5, 2013 |df=mdy-all |date=July 2010}} 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.The rescue of [http://db.yadvashem.org/righteous/family.html?language=en&itemId=6601540 Roald Hoffmann] {{webarchive|url=https://web.archive.org/web/20161013065343/http://db.yadvashem.org/righteous/family.html?language=en&itemId=6601540 |date=October 13, 2016 }} at Yad Vashem website{{cite book|title= Roald Hoffmann, interviewed by David J.

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.{{cite web |url=https://www.youtube.com/watch?v=DsSxheYLtxU |title=The Moth: The Long Ukrainian Winters - Roald Hoffmann |website=YouTube |date=January 15, 2012 }} featuring Roald Hoffman, lecture at the World Science Festival. {{Cite web |url=http://worldsciencefestival.com/videos/moth_the_long_ukrainian_winters |title=World Science Festival Video : Moth: The Long Ukrainian Winters |access-date=January 13, 2012 |archive-date=January 15, 2012 |archive-url=https://web.archive.org/web/20120115223218/http://worldsciencefestival.com/videos/moth_the_long_ukrainian_winters |url-status=bot: unknown }} 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.[https://www.npr.org/templates/story/story.php?storyId=5519776 The Tense Middle] {{webarchive|url=https://web.archive.org/web/20180223051250/https://www.npr.org/templates/story/story.php?storyId=5519776 |date=February 23, 2018}} by Roald Hoffmann, story on NPR.

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.[http://jta.org/news/article/2009/07/20/1006633/holocaust-monument-dedicated-in-western-ukraine Holocaust monument dedicated in western Ukraine] {{webarchive|url=https://web.archive.org/web/20120516012511/http://www.jta.org/news/article/2009/07/20/1006633/holocaust-monument-dedicated-in-western-ukraine |date=May 16, 2012}}.

Hoffmann married Eva Börjesson in 1960. They have two children, Hillel Jan and Ingrid Helena.

He describes himself as "an atheist who is moved by religion."Liberato Cardellini: "A final and more personal question: You defined yourself as 'an atheist who is moved by religion'. Looking at the tenor of your life and the many goals you have achieved, one wonders where your inner force comes from." Roald Hoffmann: "The atheism and the respect for religion {{sic|come fo|rm}} the same source. I observe that in every culture on Earth, absolutely every one, human beings have constructed religious systems. There is a need in us to try to understand, to see that there is something that unites us spiritually. So scientists who do not respect religion fail in their most basic task—observation. Human beings need the spiritual. The same observation reveals to me a multitude of religious constructions—gods of nature, spirits, the great monotheistic religions. It seems to me there can't be a God or gods; there are just manifestations of a human-constructed spirituality."

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. In 1965, he went to Cornell University and has remained there, where he is a professor emeritus.

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.{{cite web|title=Robert Burns Woodward|website=Science History Institute|url=https://www.sciencehistory.org/historical-profile/robert-burns-woodward|access-date=20 March 2018|url-status=live|archive-url=https://web.archive.org/web/20180321132304/https://www.sciencehistory.org/historical-profile/robert-burns-woodward|archive-date=March 21, 2018|df=mdy-all|date=June 2016}} For this work Hoffmann received the 1981 Nobel Prize in chemistry, sharing it with Japanese chemist Kenichi Fukui,{{Cite journal | last1 = Buckingham | first1 = A.

In his Nobel Lecture, Hoffmann introduced the isolobal analogy for predicting the bonding properties of organometallic compounds.{{cite web|last1=Hoffmann|first1=Roald|title=Building bridges between inorganic and organic chemistry - Nobel lecture, 8 December 1981|url=https://www.nobelprize.org/nobel_prizes/chemistry/laureates/1981/hoffman-lecture.pdf|website=Nobel Prize|access-date=20 March 2015|url-status=live|archive-url=https://web.archive.org/web/20141008042914/http://www.nobelprize.org/nobel_prizes/chemistry/laureates/1981/hoffman-lecture.pdf|archive-date=October 8, 2014|df=mdy-all}}

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.

Since the spring of 2001, Hoffmann has been the host of the monthly series Entertaining Science at New York City's Cornelia Street Cafe,{{cite web|title=A Brief History|url=http://www.corneliastreetcafe.com/about.html|work=The Cornelia Street Café|access-date=March 22, 2013|url-status=dead|archive-url=https://web.archive.org/web/20130708121800/http://corneliastreetcafe.com/about.html|archive-date=July 8, 2013|df=mdy-all}} which explores the juncture between the arts and science.
