Sir Hans Heysen, 1877-1968, German-born Australian painter, especially of landscapes and of the lives of the German farmers of Hahndorf in South Australia. He was a conservationist ahead of his time, buying neighbouring properties to prevent felling of stands of beautiful eucalypts, and he propagated old roses from the local cemetery. His house and garden at 'The Cedars', preserved by his descendants, are well worth visiting.
