Tshao Tzu-khai [Cao Cikai 曹慈凱] built the Sino-British Science Cooperation Office in Chongquing. H.T.Huang's account in 'Explorations in the history of S+T in China' (Shanghai 1980, p.71), notes that the building was nearly ready in late Jul. 1944. Joseph Needham’s South West diary records arrival at the 'new house' on their return on 31 Oct. The first entry on 1 Aug. records 'fiddling with it [truck] below our new house', so they moved to the new office at the end of Jul. 1944.
The file includes:
- Photocopies of correspondence between Joseph Needham and Tshao Tzu-khai, some found in Joseph Needham's China 1964 travel file
- Material from Cao’s son, Cao Yinlong, sent in 2006.
