Zhou Youguang, also known as Chou Yu-kuang or Chou Yao-ping, was a Chinese economist, linguist, sinologist, and supercentenarian. He has been credited as the father of pinyin, the most popular romanization system for Chinese, which was adopted by the People's Republic of China (PRC) in 1958, the International Organization for Standardization (ISO) in 1982, and the United Nations in 1986.
