Hardoyo was born in Tulungagung in East Java in 1934, the son of a school teacher who was banished to a swampy malaria infested region of Blitar for opposing the closing of unregistered private schools by the colonial government in 1932. He spent a year in Dutch language primary school until it closed after the arrival of the Japanese. Towards the end of the Occupation he delivered anti-Japanese leaflets for his father. During the revolution he was a member of the struggle organisation Mobilisasi Pelajar (Mobilised Students). In the early 1950s he entered the Faculty of Social and Political Affairs at Gadjah Mada University and began to immerse himself
in radical politics . In 1962 he became national president of CGMI, the communistleaning Indonesian Student Movement Concentration, and from 1964 he was a member of the Indonesian Communist Party (PKI) Politbureau’s foreign affairs and youth departments. After his release from prison in 1979, he rebuilt his life as a translator and editor in the publishing firm Pustaka Sinar Harapan. As an advocatefor the human rights of ex-political prisoners at the Indonesian Council of Churches,he started the e-List Wahana@centrin.net.id.
Bung Har, as he was universally known, made several starts on writing his autobiography before his death in December 2006. However he was too immersed in the present, particularly after the fall of Suharto in 1998, helping fellow ex-political prisoners and writing analyses of Indonesian politics for his e-List, ever to complete the task.
