I mentioned Saint-John University in earlier posts. Another famous alumni of the main University of Old Shanghai is Zhou Youguang, the man who invented Pinyin. Born in 1906, he went to the US to work as a Wall Street Banker after graduation. Returning to China after 1949, he lead the committee that created Pinyin, introduced to school in China 1958. The most incredible is that is still alive and writing is own blog on Weibo (in Chinese only).
