Bramwell Seaton Bonsall (M.A., B.D., D.Litt. (Lond.)) was a Wesleyan Methodist missionary to China from 1911 to 1926. He later became a translator.
In the late 1920s he obtained his doctorate, which involved translating the complete Records of the Warring States. In his retirement in the 1950s he completed a translation of all 120 chapters of Dream of the Red Chamber. The manuscript is now held by the British Library in London. It was accepted for publication by the Asia Society of New York, but the project was abandoned when publishing company Penguin announced its proposed translation by David Hawkes, with John Minford.
