British diplomatist and Sinologist who developed the famous Wade-Giles (Wade-Giles romanization) system of romanizing the Chinese language.

The elder son of an English army officer, Wade graduated from Trinity College, Cambridge (1837), and entered the army. Sent to China in 1842, he began an earnest study of Chinese and eventually became an official interpreter, being one of the few officers who knew the Chinese language. After a visit to England in 1845, he became part of the diplomatic corps in China, serving in various posts over the years in Nanjing, Hong Kong, Beijing, and elsewhere and engaging in such important negotiations as those for the Treaty of Tianjin (1857), ending the second Opium War, and those for the Chefoo (Yantai) Convention (1876), opening new treaty ports. He was knighted in 1875.

After retiring in 1883, Wade returned to Cambridge and in 1888 was elected the university's first professor of Chinese. He had already written extensively on Chinese studies, his Peking Syllabary (1859) providing the basis of the Wade-Giles system of Chinese romanization, which was long the most popular form of romanization in the West as well as in China (even after the official introduction of Pinyin (Pinyin romanization) in 1958 and its adoption in 1979). On his death Wade left a large library of Chinese books to the university.
