Nathaniel Wallich
By 1813 he took great interest in the flora and natural vegetation of India. He also went on expeditions to Nepal, West Hindustan, and lower Burma. Wallich travelled to Nepal in 1821, one of the very first Englishmen to go there, and returned with many new plants. During 1837 and 1838, Nathaniel Wallich served as Professor of Botany in Calcutta Medical College.
