Maharani Wisma Susana Siregar

Siregar was born on 5 June 1925 in Liverpool, England, the daughter of Nuriah Sabiah Nasution and Hasan Basari Siregar, a civil servant. She took ballet and voice, and studied in Soviet Union.

Siregar was introduced to President Sukarno, a friend of her father's as a child Her parents rejected his marriage proposal because they did not want her to be in a polygamous marriage. Siregar later married Firdaus Harahap, an East Nusa Tenggara police chief, and they had had three daughters: Roswita, Linda, and Mona. Sukarno later moved his family to Jakarta and sent Hoegeng Iman Santoso, Sutan Sjahrir, and Hamengkubuwono IX to persuade Harahap to divorce Siregar. Sukarno was 23 years her senior, and already had a daughter, Siti Aisyah Margaret Rose, who became a banker. They spent their time jogging at Bogor Palace and ate sunny side eggs cooked by her. When Sukarno married Naoko Nemoto in 1962, Siregar divorced him. She later remarried Harahap and gave birth to another daughter, Meli.

In opposition to Dutch colonialism, she tore up the Dutch flag and replaced it with an Indonesian flag, which earned her an award. After that she maintained a low profile life.

In an interview in 2010, Siregar stated that she felt sad seeing the poor condition of the Indonesian people, which motivated her to adopt a simple life. She gave Sukarno's inheritance to her children and orphan kids, and wished to be buried next to him when she died.
