Ubud is a town in central Bali, Indonesia, considered the arts and culture center of the island. Ubud has a population of about 8,000 people, but it is becoming difficult to distinguish the town itself from the villages that once surrounded it. Ubud gets it name from the balinese word ubad (medicine).[citation needed] Tourism on the island developed when Walter Spies came to Ubud, an ethnic German born in Russia who taught painting and music, and dabbled in dance. Spies and foreign painters Willem Hofker and Rudolf Bonnet entertained celibrities including Charlie Chaplin, Noel Coward, Barbara Hutton, H.G. Wells and Vicki Baum. They brought in some of the greatest artists from all over Bali to teach and train the Balinese in arts, helping Ubud become the cultural centre of Bali. A new burst of creative energy came in the 1960's in the form of Dutch painter Arie Smit (1916-), developing The Young Artists Movement. There are many museums spread all over Ubud, including Museum Rudana.
