From Wikipedia, the free encyclopedia

Yuan Tseh Lee (Chinese: 李遠哲; pinyin: Lǐ Yuǎnzhé; Wade–Giles: Li³ Yüan³-che²; Pe̍h-ōe-jī: Lí Oán-tiat; born 19 November 1936) is a Taiwanese chemist and a Professor Emeritus at the University of California, Berkeley.[1][2][3][4] He was the first Taiwanese Nobel Prize laureate who, along with the Hungarian-Canadian John C. Polanyi and American Dudley R. Herschbach, won the Nobel Prize in Chemistry in 1986 "for their contributions to the dynamics of chemical elementary processes".[3][5]

Lee's particular physical chemistry work was related to the use of advanced chemical kinetics techniques to investigate and manipulate the behavior of chemical reactions using crossed molecular beams.[3][5] From 15 January 1994 to 19 October 2006, Lee served as the President of the Academia Sinica of Taiwan.[4] In 2011, he was elected head of the International Council for Science.[4]

Lee was born to a Hokkien family in Shinchiku City (modern-day Hsinchu city) in northern Taiwan, which was then under Japanese rule, to Lee Tze-fan, an artist, and Ts'ai P'ei (蔡配; Cài Péi), an elementary school teacher from Goseikō Town (梧棲港街), Taichū Prefecture (Wuqi, Taichung).[1][3][4] Lee is a Hokkien with ancestry from Nan'an City, China.[6] Lee played on the baseball and ping-pong teams of Hsinchu Elementary School, and later studied at the Hsinchu Senior High School, where he played tennis and trombone.

Due to his achievements in high school, he was exempted from the entrance examination and directly admitted to National Taiwan University. He earned a BSc in 1959.[1][3] He earned his MS from National Tsing Hua University in 1961 and his PhD from the University of California, Berkeley in 1965 under the supervision of Bruce H. Mahan.[1][3] He was a member of the Chemistry International Board from 1977 to 1984.[4]


Contributions to chemistry

In February 1967, he started working with Dudley Herschbach at Harvard University on reactions between hydrogen atoms and diatomic alkali molecules and the construction of a universal crossed molecular beams apparatus. After the postdoctoral year with Herschbach he joined the University of Chicago faculty in 1968. In 1974, he returned to Berkeley as professor of chemistry and principal investigator at the Lawrence Berkeley National Laboratory, becoming a U.S. citizen the same year. Lee is a University Professor Emeritus of the University of California system.[7]

Road to Nobel prize

One of the major goals of chemistry is the study of material transformations where chemical kinetics plays an important role. Scientists during the 19th century stated macroscopic chemical processes consist of many elementary chemical reactions that are themselves simply a series of encounters between atomic or molecular species. In order to understand the time dependence of chemical reactions, chemical kineticists have traditionally focused on sorting out all of the elementary chemical reactions involved in a macroscopic chemical process and determining their respective rates.

Swedish chemist Svante Arrhenius studied this phenomenon during the late 1880s, and stated the relations between reactive molecular encounters and rates of reactions (formulated in terms of activation energies).

Other scientists at the time also stated a chemical reaction is fundamentally a mechanical event, involving the rearrangement of atoms and molecules during a collision. Although these initial theoretical studies were only qualitative, they heralded a new era in the field of chemical kinetics; allowing the prediction of the dynamical course of a chemical reaction.

In the 1950s, 1960s and 1970s, with the development of many sophisticated experimental techniques, it became possible to study the dynamics of elementary chemical reactions in the laboratory. Such as the analysis of the threshold operating conditions of a chemical laser or the spectra obtained using various linear or non-linear laser spectroscopic techniques.

Professor's Lee's research focused on the possibility to control the energies of the reagents, and to understand the dependence of chemical reactivity on molecular orientation, among other studies related to the nature of reaction intermediates, decay dynamics, and identifying complex reaction mechanisms. To do so, Professor Lee used a breakthrough laboratory technique at the time, called the "crossed molecular beams technique", where the information derived from the measurements of angular and velocity distributions allowed him and his team to understand the dynamics of elementary chemical reactions.[8]

During his tenure, Lee has worked to create new research institutes, advance scientific research within Taiwan, and to recruit and cultivate top scholars for the Academic Sinica.

In 2010, Lee said that global warming would be much more serious than scientists previously thought, and that Taiwanese people needed to cut their per-capita carbon emissions from the current 12 tons per year to just three. This would take more than a few slogans, turning off the lights for one hour, or cutting meat consumption, noting: "We will have to learn to live the simple lives of our ancestors." Without such efforts, he said, "Taiwanese will be unable to survive long into the future".[9]

He has been involved with the Malta Conferences, an initiative designed to bring together Middle Eastern scientists. As part of the initiative, he offered six fellowships to work on the synchrotron in Taiwan.[10]

Personal life

Lee's father was a well-known painter in Taiwan. His mother was an elementary school teacher, and his elder brother, Yuan-Chuan Lee, has been a professor in at Johns Hopkins University for 40 years, awarded the honor Special Chair Lectureship in Academia Sinica in Taiwan. Besides, his younger brother, Yuan-Pern Lee, also awarded this honor. Lee's sister, Chi-Mei Lee has served as a professor in National Chung Hsing University.[11]

In 2003, he was one of 22 Nobel Laureates who signed the Humanist Manifesto.[12]

Political role

Lee played an important role during the 2000 Presidential Election and since then has been a supporter of the Pan-green coalition which advocates Taiwan independence. In the last week of the election he announced his support for the candidacy of Chen Shui-bian who subsequently won a narrow victory over James Soong. Chen intended to nominate Lee to become Premier, but Lee declined after a few days of deliberation. Lee has been the President of the Academia Sinica since 1994 and renounced his U.S. citizenship to take the post.[13]

At the request of Chen, Lee was the Republic of China's representative in the 2002 APEC leaders' summit in Mexico. (Presidents of the Republic of China have been barred from joining the APEC summits because of objections from the People's Republic of China.) Lee represented Chen again in the 2003 and 2004 APEC summits in Thailand and Chile, respectively.[14]

In January 2004, he and industrial tycoon Wang Yung-ching and theatre director Lin Hwai-min issued a joint statement asking both Chen Shui-bian and Lien Chan to "drop hatred and extreme behavior and resort to honesty." This, and other critical statements of the President, led to speculation that he would not back Chen again in the 2004 elections until he issued a statement of support for the DPP on 17 March, three days before polls opened. He was elected President of the International Council for Science in 2008, to start his term in 2011.[15]

During the 2012 Republic of China presidential elections, Lee expressed his support for DPP candidate Tsai Ing-wen. In early 2016, he appeared and addressed a rally by New Power Party-a party formed by student activists involved in the Sunflower Movement.[16]

Climate change

Yuan Lee has signed the 2015 Mainau Declaration expressing concern about anthropogenic climate change.

Wu Chien-Shiung Foundation

Lee was one of the four Nobelists who established the Wu Chien-Shiung Foundation.
