044 - Catalysts Paul Andersen explains how catalysts can speed up a reaction without being consumed in the reaction. Catalysts can lower the activation energy of reaction be stabilizing the transition state. They can also create new reaction pathways with new reaction intermediates that lower the overall activation energy.

Herbert C. Brown shared the 1979 Nobel Prize in Chemistry with Georg Wittig "for their development of the use of boron- and phosphorus-containing compounds, respectively, into important reagents in organic synthesis." He was born in London to Ukrainian Jewish immigrant parents. The family moved to Chicago when Brown was two years old.

Henry Taube won the 1983 Nobel Prize in Chemistry "for his work on the mechanisms of electron transfer reactions, especially in metal complexes." Born in Saskatchewan, Canada, he came to the United States to earn his Ph.D. at Berkeley. He went on to work at Cornell, the University of Chicago and Stanford.

Charles J. Pedersen shared the 1987 Nobel Prize in Chemistry with Donald Cram and Jean-Marie Lehn "for their development and use of molecules with structure-specific interactions of high selectivity." Pedersen was born in Busan, Korea in 1904 to a Norwegian father and a Japanese mother. In 1922 he came to the United States to study at the University of Dayton, Ohio. He worked as a chemist at Dupont for 42 years.

Venkatraman Ramakrishnan shared the 2009 Nobel Prize in Chemistry "for studies of the structure and function of the ribosome." He was born in Chidambaram, India and obtained his Ph.D. from Ohio University in 1976

Alan MacDiarmid shared the 2000 Nobel Prize in Chemistry "for the discovery and development of conductive polymers." Born in New Zealand, he came to the U.S. on a Fulbright Fellowship in 1951 and spent 45 years on the chemistry faculty of the University of Pennsylvania.

Yuan T. Lee shared the 1986 Nobel Prize in Chemistry with Dudley Herschbach and John Polanyi "for their contributions concerning the dynamics of chemical elementary processes." Born in Taiwan, he earned his Ph.D. at U.C. Berkeley in 1965.

Aziz Sancar shared the 2015 Nobel Prize in Chemistry "for mechanistic studies of DNA repair." He was born in Turkey and received his Ph.D. at the University of Texas at Dallas.

Michael Levitt shared the 2013 Nobel Prize in Chemistry "for the development of multiscale models for complex chemical systems." Born in Pretoria, South Africa, he lived in Israel before moving to the U.S. to teach at Stanford.

Roald Hoffmann shared the 1981 Nobel Prize in Chemistry with Kenichi Fukui "for their theories, developed independently, concerning the course of chemical reactions." Born in an area of Poland that is now part of Ukraine, Hoffman lost most of his family in the Holocaust. He emigrated to the U.S. in 1949.
