H. J. de Graaf
Hermanus Johannes de Graaf (2 December 1899 – 24 August 1984) was a Dutch historian specialising in the history of Java, Indonesia, the world's most populous island. Trained as historian at Leiden University, he moved to Batavia (today's Jakarta) to take a government job, and later became a teacher for various schools in Indonesia. At the same time, he pursued his interest in the history of Indonesia and published books and articles on the topic. After a brief assignment at the University of Indonesia, he returned to the Netherlands. He taught at various institutions, including Leiden, until 1967 and continued to publish scholarly works, even after his retirement. He suffered a serious stroke in 1982 and died two years later.His works covered the history of Indonesia in general, with emphasis on sixteenth- and seventeenth-century Java. His works extensively consulted both European and Indonesian sources, one of the first trained historians to do so. Historian M. C. Ricklefs called him the "father of the study of Javanese history", while Javanist Theodoor Gautier Thomas Pigeaud said his works formed "a substantial contribution to the study of the national history of Indonesia."
