Roald Hoffmann (born July 18, 1937) [Hoffmann's birth name was Roald Safran. Hoffmann is the surname adopted by his stepfather in the years after World War II] is an American theoretical chemist who won the 1981 Nobel Prize in Chemistry. He currently teaches at Cornell University in Ithaca, New York.

Early life

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. He and his mother were among the only members of his immediate family to survive the Holocaust, an experience which strongly influenced his beliefs and work. (A grandmother and several aunts, uncles, and cousins also survived.) [ [ The Tense Middle] by Roald Hoffmann, story on NPR. Retrieved 29 September 2006.] They immigrated to the United States in 1949.

Academic credentials

Hoffmann graduated in 1955 from New York City's Stuyvesant High School, [cite web |url= |title=Roald Hoffmann's land between chemistry, poetry and philosophy |accessdate=2007-10-31] 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 and his Doctor of Philosophy degree, both from Harvard University, while working under the subsequent 1976 chemistry Nobel Prize winner William N. Lipscomb, Jr..

Chemistry interests

Hoffmann has investigated both organic and inorganic substances, developing computational tools and methods such as the extended Hückel method, which he proposed in 1963.

He also developed, with Robert Burns Woodward, rules for elucidating reaction mechanisms (the Woodward-Hoffmann rules). He also introduced the isolobal principle.

Artistic interests

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 a play called "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.

Hoffmann stars in the "World of Chemistry" video series with Don Showalter.

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

Hoffmann and Brian Alan are produced the project of English song “Dedication of Love“. That planned to raise funds by this worldwide single release to be contributed to the Sichuan Earthquake to help rebuild the area. The artists are BoA, Wei Wei, Phoebe, Rusiana Gaitana, Sonu, Ruth Sahanaya and the other 3 are from Paris, Brazil and Oman. [ [ BoA sings for SICHUAN’S EARTHQUAKE ! « BoA’s Jewelry Box ] ]
