In March 1807, Nathaniel Wallich, a young Danish surgeon left his home in Copenhagen towards India. During the troubles of the Napoleonic Wars, it was not possible to foresee, that he was to emerge as one of the most prominent botanists of the globe in nineteenth century. Wallich spent most of his adulthood in India and, as the long-time superintendent of the Calcutta Botanic Garden, gained extensive expertise on Indian flora. A truly global communication network emerged from his desk facing the River Hooghly, reaching out to eminent specialists as well as amateur researchers long forgotten today. He conducted research trips to Nepal, as well as to South East Asia and may be deemed to be one of the founding fathers of tea production in Assam. This book is based on the enormous correspondences of Wallich, preserved in libraries across Calcutta, London, Copenhagen, Hamburg, Munich and many other places. The work also studies Wallich’s professional and private life. It aims to approach a long career marked by biographical ruptures and contradictions, but at the same time by continuity. It furthermore explains the tight links between supposedly neutral botanical studies and the emergence of British colonial power in India.
