Johan Rudolf Bonnet (30 March 1895, Amsterdam - 18 April 1978, Laren) was a Dutch artist who lived much of his life in the town of Ubud on Bali, Indonesia.
In 1920, he journeyed to Italy with his parents, during which trip he produced an enormous number of drawings of people, village scenes and landscapes.
He spent the remainder of World War II in internment camps in Pare-Pare, Bolong and Makassar.
He was expelled from Indonesia in 1957 after he refused to finish a portrait of President Sukarno;[6] he was able to return 15 years later.
Bonnet, together with Walter Spies, I Gusti Nyoman Lempad and Cokorde Gde Agung Sukawati formed the Pita Maha (Great Spirit, Guiding inspiration) in 1936 to select the artists whose works were found to be good enough to be sold in a number of galleries and to be included in exhibitions elsewhere in the Indies, The Netherlands and the United States.
