Tsung-Dao Lee (

New York City, where he taught from 1953 until his retirement in 2012.[1]

In 1957, at the age of 30, Lee won the

Chen Ning Yang[2] for their work on the violation of the parity law in weak interactions, which Chien-Shiung Wu experimentally proved from 1956 to 1957, with her well known Wu experiment
.

Lee remains the youngest Nobel laureate in the science fields after

William L. Bragg (who won the prize at 25 with his father William H. Bragg in 1915) and Werner Heisenberg (who won in 1932 also at 30). Lee and Yang were the first Chinese laureates. Since he became a naturalized American citizen in 1962, Lee is also the youngest American ever to have won a Nobel Prize.[3]

Biography

Family

Lee was born in

ancestral home in nearby Suzhou. His father Chun-kang Lee (李駿康; Lǐ Jùn-kāng), one of the first graduates of the University of Nanking, was a chemical industrialist and merchant who was involved in China's early development of modern synthesized fertilizer. Lee's grandfather Chong-tan Lee (李仲覃; Lǐ Zhòng-tán) was the first Chinese Methodist Episcopal senior pastor of St. John's Church in Suzhou (蘇州聖約翰堂).[4][5][additional citation(s) needed

Lee has four brothers and one sister. Educator Robert C. T. Lee was one of T. D.'s brothers.[6] Lee's mother Chang and brother Robert C. T. moved to Taiwan in the 1950s.[citation needed]

Early life

Lee received his secondary education in Shanghai (High School Affiliated to Soochow University, 東吳大學附屬中學) and

National Che Kiang University, where he studied in 1943–1944.[5][additional citation(s) needed
]

However, again disrupted by a further Japanese invasion, Lee continued at the National Southwestern Associated University in Kunming the next year in 1945, where he studied with Professor Wu Ta-You.[5]

Life and research in the U.S.

Chien-Shiung Wu, designer of the Wu experiment that violated parity

Professor Wu nominated Lee for a Chinese government fellowship for graduate study in the United States. In 1946, Lee went to the

University of California at Berkeley from 1950 to 1951.[7][5]

In 1953, Lee joined

parity violation. Encouraged by this feasibility study, Lee made a systematic study of possible Time reversal (T), Parity (P), Charge Conjugation (C), and CP violations in weak interactions with collaborators, including C. N. Yang. After the definitive experimental confirmation by Chien-Shiung Wu and her assistants that showed that parity was not conserved, Lee and Yang were awarded the 1957 Nobel Prize in Physics. Wu was not awarded the Nobel prize, which is considered one of the largest controversies in Nobel committee history.[8]

In the early 1960s, Lee and collaborators initiated the important field of high-energy

KLN theorem for dealing with these divergences, which still plays an important role in contemporary work in QCD, with its massless, self-interacting gluons. In 1974–75, Lee published several papers on "A New Form of Matter in High Density", which led to the modern field of RHIC physics, now dominating the entire high-energy nuclear physics field.[citation needed
]

Besides

black holes throughout the 1980s and 1990s.[citation needed
]

From 1997 to 2003, Lee was director of the RIKEN-BNL Research Center (now director emeritus), which together with other researchers from Columbia, completed a 1 teraflops supercomputer QCDSP for lattice QCD in 1998 and a 10 teraflops QCDOC machine in 2001.[citation needed] Leading up to 2005,[9] Lee and Richard M. Friedberg developed a new method to solve the Schrödinger equation, leading to convergent iterative solutions for the long-standing quantum degenerate double-wall potential and other instanton problems. They also did work on the neutrino mapping matrix.[10]

Lee was one of the 20 American recipients of the Nobel Prize in Physics to sign a letter addressed to President George W. Bush in May 2008, urging him to "reverse the damage done to basic science research in the Fiscal Year 2008 Omnibus Appropriations Bill" by requesting additional emergency funding for the Department of Energy's Office of Science, the National Science Foundation, and the National Institute of Standards and Technology.[11]

Educational activities

Soon after the re-establishment of China-American

relations with the PRC, Lee and his wife, Jeannette Hui-Chun Chin (秦惠䇹; Qín Huìjūn), were able to go to the PRC, where Lee gave a series of lectures and seminars, and organized the CUSPEA
(China-U.S. Physics Examination and Application).

In 1998, Lee established the Chun-Tsung Endowment (秦惠䇹—李政道中国大学生见习基金) in memory of his wife, who had died three years earlier. The Chun-Tsung scholarships, supervised by the United Board for Christian Higher Education in Asia (New York), are awarded to undergraduates, usually in their 2nd or 3rd year, at six universities, which are

. Students selected for such scholarships are named "Chun-Tsung Scholars" (䇹政学者).

Personal life and death

Lee and Jeannette Hui-Chun Chin married in 1950 and had two sons: James Lee (Chinese: 李中清; pinyin: Lǐ Zhōngqīng) and Stephen Lee (Chinese: 李中汉; pinyin: Lǐ Zhōnghàn). His wife died in 1996.[5]

Tsung-Dao Lee died in San Francisco on August 4, 2024, at the age of 97.[5][12][13]
