Born in Switzerland and raised in Germany, Christian went to school in Germany and Chile (Instituto Aleman and Universidad Austral). Having travelled extensively in Chile in 1972, he was finally able to see Easter Island in 1975. His first visit lead to a study visa, giving him the ability to return in 1976 to do a comparative study of Easter Island’s petroglyphs and the possible relationship between the island’s unique writing system, Rongo Rongo. While doing his research he was approached to lead tour groups on the island. His expertise in the fields of anthropology, archaeology, history and art eventually led him to lecture aboard expedition cruise ships. Christian’s main fields of interest are the History of Exploration and the Art of the Pacific Islands. When not at home or aboard ship, he can likely be found browsing in bookstores.
