On this day in 2017, Liu Xiaobo died of liver cancer a few weeks after being granted medical parole from prison. He was a writer, literary critic, human rights activist, and Nobel Peace Prize laureate. In the 1980s, he was a visiting scholar at international universities. He returned to China in 1989 to support the Tiananmen Square protests and was arrested for the first time then. In the following years, he was imprisoned several times for calling for political reform in China. During his fourth prison term, he was awarded the 2010 Nobel Peace Prize for “his long and non-violent struggle for fundamental human rights in China.” Photo: Nobel Peace Prize website.
