Sun ZHONGSHAN (aka Sun Yat-sen; Sun Wen) [1866-1925]
Dr Sun Zhongshan (Yat-sen) is generally considered to be the founder of the Chinese Republic (1911) and one of the most important figures in modern Chinese history.
He graduated from the Hong Kong College of Medicine for Chinese in 1892 and at one point thought about opening a pharmacy in the Colony.
Note: Dr Sun was known by a number of different names during his life. I have used his most popular Chinese name and added his birth name (Sun Wen) and the most common transliteration in English sources (Sun Yat-sen).
