Siti Sukaptinah Sunaryo Mangunpuspito

Siti Sukaptinah Sunaryo Mangunpuspito, also spelled Siti Soekaptinah Soenarjo Mangoenpoespito (28 December 1907 - 31 August 1991)[1] was an Indonesian women's rights activist and politician who was one of only two female members of the Investigating Committee for Preparatory Work for Independence and later became a member of the Indonesian parliament.

From a young age, Siti disagreed with arranged marriage, and believed that a woman had the right to choose her own match.

In 1932, a number of organizations combined to form Indonesian Wives (Isteri Indonesia), and Siti was appointed chair.

At the third Indonesian Women's Congress, which took place in Bandung in July 1938, she put forward the idea of a Mother's Day.

[3][4] During the Japanese occupation of the Dutch East Indies, Siti joined a number of organizations established in Java by the occupation government, including the Center of People's Power (Putera), in which she became head of the women's section from 1943 to 1944, and the Java Service Association (Jawa Hokokai) from 1944 to 1945, again serving as head of women's affairs.

Siti sat on the BPUPK committee discussing nation building, and expressed the view that an independent Indonesia should have the same form of government as that under the Japanese, but with the supreme military commander replaced by a head of state.

[3][5][8] In December 1978, to mark the fiftieth anniversary of the Indonesian Women's Congress, Siti was presented with a gold chain.
