About Herbert Giles (from Wikipedia):
Herbert Allen Giles (8 December 1845 – 13 February 1935) was a British diplomat and sinologist who was the professor of Chinese at Cambridge University for 35 years. Giles was educated at Charterhouse School before becoming a British diplomat in China. He modified a Mandarin Chinese romanisation system established by Thomas Wade, resulting in the widely known Wade–Giles Chinese romanisation system. Among his many works were translations of the Analects of Confucius, the Lao Tzu (Tao Te Ching), the Chuang Tzu, and, in 1892, the widely published A Chinese-English Dictionary.
