Soong Ch'ing-ling; Shanghai; 1920 (pinyin: Song Qingling; 27 January 1893 - 29 May 1981); also known as Madame Sun Yat-sen; was one of the three Soong sisters who; along with their husbands; were amongst China's most significant political figures of the early 20th century. She was the Vice Chairman of the People's Republic of China. She was the first non-royal woman to officially become head of state of China; acting as Co-Chairman of the Republic from 1968 until 1972. She again became head of state in 1981; briefly before her death; as President of China. Soong is sometimes regarded as Asia's first female non-monarchial head of state; although her title of Honorary President of the People's Republic of China was purely ceremonial.

As Dr Sun Yat-sen's secretary and assistant; Madam Soong Ching Ling took painstaking care of his correspondence; newspaper clippings; translation and typing. This photograph taken in Shanghai in 1920 shows Madam Soong at work in the study room.
