Wen Ho Lee (born December 21, 1939, in Taiwan) is a Taiwanese-American nuclear scientist and mechanical engineer who immigrated to the United States in 1965. He earned a B.S. from National Cheng Kung University in Taiwan and a Ph.D. in mechanical engineering from Texas A&M University in 1969. Lee worked for decades at Los Alamos National Laboratory in New Mexico, where he made significant contributions to national security research through computerized simulations of nuclear explosions, aimed at advancing scientific inquiry and enhancing the safety and reliability of the U.S. nuclear arsenal. In 1999, he became the center of a high-profile controversy when U.S. authorities accused him of mishandling classified nuclear weapons data, with allegations implying espionage for China. The case involved concerns over the theft of W-88 nuclear warhead designs and Lee's contacts with Chinese scientists. Arrested and held in solitary confinement for nine months without bail, he faced 59 felony counts, but in 2000 the charges were reduced to a single misdemeanor for improper handling of restricted data. He received a presidential pardon from Bill Clinton in 2001. Lee co-authored the memoir 'My Country versus Me' with Helen Zia, detailing the ordeal and criticizing the government's handling of the case, which many viewed as racially motivated profiling against Asian Americans. Post-incident, he has been recognized as a victim of injustice, sparking debates on civil liberties, ethnic bias in security clearances, and espionage accusation politics. He has largely stayed out of the public eye since, though his story continues to influence discussions on U.S. national security practices and the treatment of immigrant scientists.
