Early life and education
Chan was born on October 5, 1936, in San Francisco to immigrant parents originally from Southern China.[1][2] He received his secondary education in Hong Kong, then returned to the United States to attend the University of San Francisco.[1][3] Shortly afterwards, he transferred to the University of California, Berkeley, where he earned a bachelor's degree in chemistry and his doctorate in chemistry.[1][3] He completed his doctoral work under the supervision of physical chemist William Dulaney Gwinn and was awarded his PhD in 1961.[4]
Career
After receiving his doctorate, Chan completed a one-year post-doctoral fellowship in the laboratory of the Nobel laureate physicist Norman Ramsey at Harvard University and later returned to California to join the chemistry faculty at University of California, Riverside.[1] He began teaching at the California Institute of Technology in 1963.[5] Five years later, he was awarded a Guggenheim fellowship.[6] Chan received several honors throughout his career at Caltech, among them fellowship into the American Physical Society (1987) and American Association for the Advancement of Science (1992), as well as membership of Academia Sinica (1988).[7] He was appointed Caltech's first George Grant Hoag Professor of Biophysical Chemistry in 1992.[8] Chan retired from Caltech in 1997, for a position as distinguished research fellow at Academia Sinica.[5] Subsequently, Chan was named vice president of Academia Sinica under Yuan T. Lee.[5][9] Caltech granted emeritus status to Chan in 2002.[10] Upon Chan's retirement as vice president of Academia Sinica in July 2003,[11] Lee inaugurated the Sunney Chan Lecture in Chan's honor.[9] He remained affiliated with Academia Sinica as a research and visiting fellow until 2015.[5] In his later career, Chan held distinguished chair and research professorships at National Taiwan University and National Chung Hsing University.[5]
Death
Chan died May 5, 2025, at the age of 88.[12][13] He was buried two weeks later at the Holy Cross Catholic Cemetery in Colma, California.[14]
Legacy
Academia Sinica has an annual lecture series named in Chan's honor since 2003.[15]
