 A large number of Tibetans fled to India, and many found refuge in Kalimpong, enabling Peter to study the people and Tibetan culture.To speak to Tibetans directly, he started learning their language.Peter gathered anthropometric data on 3,284 persons, analysed 198 blood samples, bought clothes, jewellery, books (such as the Tengyur and Kangyur), and various other objects now found at the National Museum of Denmark and the Royal Library.
