Johanna Masdani

Johanna was among those who attended the Second Youth Congress in October 1928 and took part in pledging the Youth Pledge.^[1] In addition, Johanna also witnessed the Proclamation of Indonesian Independence that was announced by Sukarno and Mohammad Hatta on 17 August 1945.^[2] A year later, Masdani organized the building of a monument to commemorate the proclamation event. The monument was built in front of Sukarno's house where the proclamation took place on 56 Pegangsaan Timur Street (now Proklamasi Street) in Jakarta, which is now Proclamation Park (or Taman Proklamasi). This is a different monument from the monument featuring Sukarno and Hatta in the same park.^[3]

In 1961, Masdani completed her studies in the Faculty of Psychology at the University of Indonesia. She became a psychiatrist and also taught at her almamater. She continued her studies in the United States and Britain after her husband, Masdani, died in October 1967.^[1]
