Leroy Chang

Leroy L. Chang (Chinese: 張立綱; pinyin: Zhāng Lìgāng; 20 January 1936 – 10 August 2008) was an experimental physicist and solid state electronics researcher and engineer. Born in China, he studied in Taiwan and then the United States, obtaining his doctorate from Stanford University in 1963. As a research physicist he studied semiconductors for nearly 30 years at IBM's Thomas J. Watson Research Center, New York. This period included pioneering work on superlattice heterostructures with Nobel Prize-winning physicist Leo Esaki.

In 1993, Chang moved from New York to Hong Kong, switching from industrial research into academia in anticipation of the 1997 transfer of the British colony to China. He was among the first wave of recruits to the Hong Kong University of Science and Technology. Over the following 14 years he helped build the university's reputation in his roles as Dean of Science, Professor of Physics, Vice-President for Academic Affairs, and Emeritus Professor. He retired in 2001.

Honours bestowed on Chang included membership of the US National Academy of Sciences, the Chinese Academy of Sciences, and Academia Sinica, the national academy of Taiwan. Awards received included the International Prize for New Materials (1985), the David Sarnoff Award (1990) and the Stuart Ballantine Medal (1993). Chang's death in 2008 was marked with memorial services, and a symposium in his memory was held the following year.
