Herbert Allen Giles (Chinese: 翟理斯, romanized: Zhái Lǐsī; 8 December 1845 – 13 February 1935) was a British diplomat and sinologist who held the Professorship of Chinese at the University of Cambridge for 35 years. Giles was educated at Charterhouse School before becoming a British diplomat in China. He modified a Mandarin Chinese romanization system established by Thomas Wade, resulting in the widely known Wade–Giles Chinese romanization 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.
