The Wikipedia article of the day for February 20, 2026 is Zhang Jingsheng.
Zhang Jingsheng (20 February 1888 – 18 June 1970) was a Chinese philosopher and sexologist. Born to merchants in rural Guangdong, he was a militant supporter of the Tongmenghui revolutionaries. After being expelled from school, Zhang entered Peking University and became an advocate for European ideas of social Darwinism, scientific racism, and eugenics. He changed his personal name to Jingsheng, meaning 'competition for survival'. After the 1911 Revolution, Zhang went to France to study philosophy, receiving his doctorate in 1919. He soon became a professor at Peking, publishing two books advocating for a utopian society arranged around aesthetics. In 1926, he published the sexology text Sex Histories. Zhang was ridiculed by the Chinese media and academia for this work, and tabloids gave him the mocking nickname Dr. Sex. After an unsuccessful bookstore venture in Shanghai, he returned home and worked in obscurity. Zhang was persecuted during the Cultural Revolution and died in confinement.
