Fang Lizhi
Fang Lizhi (also Li-Zhi; February 12, 1936 – April 6, 2012) was a Chinese astrophysicist, vice-president of the University of Science and Technology of China, and activist whose liberal ideas inspired the pro-democracy student movement of 1986–87 and, finally, the Tiananmen Square protests of 1989. Because of his activism, he was expelled from the Chinese Communist Party in January 1987. For his work, Fang was a recipient of the Robert F Kennedy Human Rights Award in 1989, given each year to an individual whose courageous activism is at the heart of the human rights movement and in the spirit of Robert F. Kennedy's vision and legacy. He was elected an academician of the Chinese Academy of Sciences in 1980, but his position was revoked after 1989.
